Giant Chalk Dudleya or Giant Live Forever, this is in our estimation the largest and showiest of this genus native to the West Coast of North America from Oregon to Mexico. This spectacular succulent is native to the northern coast of Baja where it attaches to volcanic cliffs above the ocean. To 12″-18″ wide in a year or two the softly spiked rosette is covered in fine white powder (bloom) that can be rubbed off- that can result in a less pristine white form. Avoid pawing or poking the foliage. In spring to summer 18″ stems support clusters of orange/pink/yellow downward pointing flowers. Very pretty and it draws hummingbirds and butterflies. A fantastic container plant that can live for years happily in succulent cactus mix. Protect from severe cold (below 26ºF) and put containers in a cool unheated greenhouse in autumn. Or move to a dry under eave position. Water deeply and infrequently and able to tolerate summer water much better than others. Our Oregon native Dudleya farinosa can be kind fussy about that. Very easy to grow. Part shade to full sun. Shockingly beautiful plant. This and many Dudleyas have been vastly and illegally over collected in the wild. Ours are raised from seed which is not difficult and is even more of a pity that they are stolen in the wild.
Foliage Season: Evergreen
We have been so impressed with the performance of this small evergreen tree species that when we saw this charming narrow leaved form we snagged it. An upright growing but not wide tree to 18′ tall. The thin leaves are 4mm wide but up to 6cm long and are thinly produced so that the tree has a fine texture and is even better to view the late winter and early spring red brushy, flowers. Moderately fast growing it is also very drought tolerant. Water to establish and in summer or to speed growth otherwise it can get by on natural rainfall. Very neat and tidy and cold hardy to -5ºF. This tree is a good candidate for areas affected by subfreezing east wind- its exceptionally tolerant of that for a broad leaved evergreen. Full sun to high overhead shade ( with less of the red flowers). In time the cut branches can be brought inside and forced into bloom for arrangements. Not deer food, but i’m not as familiar with this form. Unusual, tough and beautiful. Narrow leaved Sycopsis. Tolerates many soil types including heavy soils in upland situations. SW China
Siskiyou Iris is native to the southwestern part of Oregon. Though its named after the mountain range it is more often a valley species. You see it sparsely under Oaks, Madrones, and especially Ponderosa and Jeffrey Pine woods. Never at high elevations it grows in a host of soil types but the common component is that they all dry thoroughly in summer. Do not irrigate past the Fourth of July when established OR water only to establish the first year and then set it free. Forms almost caulescent evergreen fans that are red at the base. These rise to about 14″ and are not profuse. The plants which we raise from seed are a range of pale ivory to yellow all with conspicuous darker markings on the falls. Blooms April to May. Full sun to part shade and best with some protection from afternoon sun. In habitat it is found with Sidalcea malvifora var. Asprella , Erythronium hendersonii, and Vancouveria chrysantha with interspersed clumping Fescues. Long lived. This Iris among other Pacifica species do not compete well with invasive weeds and grasses. They are native to a fairly invasive free and less competitive balanced biome. Protect them by not allowing weeds grasses from getting a foothold around this Iris. Mulch with gravel to assist. Not bothered by deer or rabbits. Not as floriferous as other species but the flowers which are larger are much showier as well. Drought adapted. Oregon native plant.
Spring bouquet viburnum or Laurusitinus is a common shrub in our climate. This form lightens up what can be a very pedestrian plant. The edges of the evergreen leaves are margined in cream with an interior of soft green. This makes a shrub that glows year round and can be used to lighten up dark corners. In autumn clusters of pink buds form and hold until mid winter. Then as the days begin to lengthen it opens these clusters which are lightly fragrant and white. Strong growing shrub that requires very little water once established. To 8′ tall and 5′ wide in 6 years. Full sun to part shade to high overhead shade. Nice looking, tough shrub native to the Mediterranean very easy to grow and long lived. If a green sport appears simply prune it off to the base to retain the variegated form. Water to establish. Not deer resistant. Excellent backdrop to a mixed border or trimmed into a contained hedge. Nice fast growing screen. Blue berries sometimes follow the flowers. Buds and flowers put on a show for months. Blooms on wood from the previous season prune after flowering if needed. Naturally dense and rounded.
This is a remarkable oak whose geographic center is in high elevation Mexico. There are several forms of this evergreen tree with remarkable qualities. Its range extends from the SW U.S. south throughout Mexico into northern Guatemala. This southwest form has shown great cold hardiness and adaptability. These are started from acorns in a garden in Medford. The parent tree was pole straight with a boisterous green rounded crown. It is remarkably tolerant of drought and is cold hardy reliably to 0ºF. Full sun in average soil for a moderately fast growing tree. The outline of its crown is oblong at first and if you remove the lower limbs it will send the crown skyward. As I said the trunk was pole straight on a tree that was 35′ tall (18′ wide) and very pretty. Doing research on this tree it was found in California that this tree literally collects pollutants from the sky with its rough leaves. Its proposed to be planted along intersections and freeways and could be a boon to lower the particulate count. Dark green foliage looks good year round. Water to establish and then none in subsequent years. Grows fast for an oak and it really adores our climate. The bark is rough with gray striations. It makes many acorns and this should be taken into account in siting. Good candidate for a street tree or a garden shade tree. Average soil, including clay soils. Full sun from every direction for the straightest tree. Syn. Quercus reticulata. This would also be a good candidate for a formal large screen. Sometimes called net leaf oak or southwestern net leaf oak. Casts moderately dense shade with time.
Compact hybrid Corokia that has larger leaves that turn from gray to bronze in cold weather. To 4′ x 3′ in 6 years. The upper parts of the stems are more like soft gray rushes before the foliage elongates. In late spring starry bright yellow flowers spangle the older growth. Occasionally its followed by orange berries. Very forgiving shrub that we have actually grown for years. It has good cold hardiness for a Corokia x virgata hybrid and its compact, dense and good looking year round. Avoid the coldest sites, gains cold hardiness with age, protect the smallest plants from temperatures below 20ºF, after several years it will be hardy to the upper single digits. Makes a great sheared hedge and its used for that purpose in its home New Zealand. Great performance at the Oregon coast. Very good in containers. especially winter containers. This shrub has a much more burgundy hue in winter as opposed to the all gray look of Corokia cotoneaster. Easy to grow. This shrub would be good to try where deer are profuse. Its excels in containers in the urban scape of down town.
This is a different form of our locally native Buckbrush. We found this at approximately 2200′ on Mary’s Peak in the Coast Range in a forest that was comprised primarily of Douglas Fir and Golden Chinquapin. This shorter shrub with smaller deep green leaves is most conspicuous in its slick gray stems. To 3′ tall by 4′ wide in 5 years. Full sun and average to poor soil. Blooms April to May with ivory colored panicles that cover the whole plant on old wood. The sweetly fragrant flowers are always buzzing with pollinators. A true low water shrub that can easily get by on only what falls from the sky, once established. This is a cold hardy and locally native evergreen shrub. Often it grows in an arching and then angular kind of way. This form is less upright. Red seedheads follow the flowers. This is a very well known and stable population in the wild that is regenerating nicely. Extraordinarily tolerant of heat and drought. Traditionally this shrub follows disturbance and was widespread in the Willamette Valley often as a meadow component with Rosa nutkana and Amelanchier, Excellent with native clumping grasses, perennials, and annuals. Oregon native plant.
Xera Plants Introduction
Oregon cut leaf gold thread is a widespread but not common evergreen perennial that is found in dry shade on the west side of the Cascades. Native primarily to Oregon it extends north into Washington and is rare south into California. A colony creating perennial that has handsome, intricate deep green foliage. The arrow shaped leaves are arranged in rosettes along the expanding yellow stolons. The effect is a dense cover that expands at a slow rate. In spring sparse thread like flowers are curious followed by swollen seed pods arranged in a circle. Rich to average soil in shade to dappled shade, though if pushed it can tolerate a little sun. Good year round appearance. It may be cut back at the end of winter, but I haven’t really found this to be necessary. Use its best attributes, adaptation to dry shade and evergreen good looks as a limited groundcover beneath woodland perennials or at its best on the forest floor. Not a wide scale groundcover and clumps expand at a slow/moderate pace. Not adapted to compacted or clay soils. Best in heavy duff on the forest floor. Great in shade containers at the foot of Aspidistra . Not bothered by deer. Limited quantities. It derives its common name from the bright yellow roots and stolons. Water until you see good new growth then set it free. Oregon native plant.
Wonderful dense, arching and low growing conifer for full sun and only occasional water when established. This cold hardy conifer is native to the highest elevations of Tasmania up into eastern Australia. In the summer the fine but substantial needles turn to dusty blue. The arrival of colder weather brings a distinct and beautiful soft purple cast. To 2′ tall and arching to 5′ tall in 7 years. Long lived and carefree conifer for full sun to very light shade. Dense and blocks weeds. Excellent large scale, weed supressing low water shrub. This cultivar originated in New Zealand and was released as a cultivar in 1994. Very good deer and rabbit resistance. Excellent appearance year round. It has been hardy slightly below 0ºF. Easy to grow.
Mudgee Wattle or simply showy wattle this is an extremely pretty small tree that requires a very protected location to thrive. Blue/green bipinnate leaves are intricate and pretty. In very late winter to early spring a stunning show of electric yellow puff ball flowers. It covers the whole tree weighing down the limbs in full bloom. To 12′-15′ tall in rich to average soil and it absolutely requires full sun. Excellent against a south facing wall. The flowers truly are showy and glow from quite a distance. Native to New South Wales and southern Queensland on table lands. Cold hardy to at least 18ºF- it should take colder temperatures if sited correctly. As with all Acacias it is extremely fast growing when young. Consistent summer water. Loved by hummingbirds and insects in general. This special small tree can begin its life in a spindly way. Full sun and regular water strengthens this growth. Excellent, and best adapted for the Oregon coast. It adapts to life on sand (with supplemental water) as well as well developed soils. Not bothered by deer. The large delicate leaves are blue/gray and are pretty year round. This Acacia is not as cold hardy as Acacia covenyi and is hardier than Acacia pravissima. Following bloom long dusty purple seed pods contrast against the blue/gray foliate. Bark is black to dark brown. Inland it is considered experimental. Eastern Australia.
Passaflora x ‘Betty Myles Young’
Stellar passion vine with distinctly purple tepals and deep black to blue on the interior of the flower. Vigorous vine for a protected location in full sun. To 12′ in a season and blooming continuously from June to October. Attaches itself by winding tendrils. The flowers appear on new wood, as the vine grows it produces new flowers. Average to rich soil with REGULAR irrigation during the first season and then occasionally. Passafloras must be well established going into their first winter. In half of the winters (below 20ºF) it can freeze to the ground. It will then rapidly break from the base when truly warm weather arrives. Mulch heavily the first winter, Place on a trellis against warm, sunny wall for the best performance. The intricate and beautiful flowers are about 4″ across. Sometimes sets inedible fruit. Passion vines are loved by everybody but especially children. The toy-like flowers enchant. Sweetly fragrant flowers up close. Loved by hummingbirds. One of the best hybrid Pnassafloras for our gardens. Moderate deer resistance
A very mysterious Gardenia that I got from the east coast and whose flowers are ENORMOUS and powerfully fragrant. Everything about this hardy Gardenia is big. The leaves are 5″x 3″ and are forest green and delightfully glossy. A moderately fast growing evergreen shrub to 6′ x 6′. Full sun but best in dappled shade in a protected location. Regular, consistent water is crucial. Gardenias like heat and water. Poorly irrigated plants will show yellow leaves on the interior of the plant before wilting. This is especially important since we’ve had consecutive dry springs and most likely you will need to water this plant beginning in April. Rich soil with regular water. Protect from subfreezing wind, and plant in rich soil with ample compost. Apply a handful of all organic fertilizer in early summer. The enormous flowers begin i July and continue to October. The only information I can find on this cold hardy cultivar is that it is particularly resistant to pests. Since Gardenias in our climate aren’t really pest magnets this is moot, but good to know. Spectacular flowers are 5″ across and semi-double. Excellent for corsages and even for floating in a bowl, one flower will perfume a wide area. It is crucially important that this shrub be well established going into winter otherwise its hardiness to cold will be compromised. Limited quantities.
Obscure but exceedingly handsome and reliable shrub for hedges, specimens, eventually a small tree. Rounded leaves are good looking year round and especially when they first emerge brilliant salmon red before settling to dark green. This is the most showy display on this plant and it lasts for weeks. In mid-late summer small pendant white/cream flowers are nestled among the leaves, you really have to look to see them. Clean evergreen whose foliage is never marred by fungus or cold. Full sun to high overhead shade. To 8′-10′ tall and about half as wide. With great age and no pruning it can achieve small tree status and it forms attractive cloud like crowns of foliage. As a hedge it excels. Plant 2 gallon plants on 3′ centers and mulch. Irrigate about once a week until you see good new growth. Established plants are very tolerant of dry conditions. Theaceae- Camellia family. Excellent cold hardiness to 0ºF, tolerates some subfreezing wind. Excellent companion plant for Rhododendrons, Pieris, Illicium. Full sun to quite a bit of shade. Native to Japan. Good looking tough plant. Light deer resistance.
Excellent, dwarf/very small Mountain Yew Pine hybrid. To just 2′ tall forming a very dense plant to 3′ wide in 10 years. Late in the summer and autumn it pushes beautiful red stained growth that persists through winter. This small formal looking plant has deep green fine, yew like foliage the remainder of the year. Adaptable conifer that takes clay soils as well as sand. Occasional deep watering not only improves appearance it guarantees that the late summer and autumn color change to red is more dramatic. Full sun to very light shade (with a slightly more open habit). Tiny green pillar shaped flowers can turn into red berries. Very easy to grow for a formal, clean or modern aesthetic. The dense growth is a great fine texture that mixes brilliantly with smaller ornamental grasses and other small conifers. Hybrid between two southern hemisphere Podocarpus. Does not require pruning or maintenance of any kind. Tiny needles are but 4mm long. CUTE. Long lived. Light deer resistance.
Frangula (Rhamnus) californica ‘Josephine County’
(California) Coffee Berry. Greg collected the berries/seed from this evergreen shrubby species in southwestern Oregon. In Josephine county it is a common dry shade understory component of both the forest and in open stands in chaparral. A light and gaunt evergreen with slightly glossy convex leaves that hang on the tips of the gray branches. In spring/ summer tiny green flowers morph into the familiar berries. They start green move to red and arrive at black/brown. To 6′ tall x 6′ wide on average. Growth in rich soil is much more verdant and dense. In dry shade, its natural haunt, it assumes its most common form. Birds will spread this tough shrub that is ideal for wild scaping, xeric landscaping, rural areas. Perhaps its most wonderful characteristic is that it is deer resistant- they will munch but it will cause the plant to return twice as dense and verdant. Leaves are glossy on top and blue/gray on the reverse and persist for 3-5 years. Full sun to quite a bit of shade in average to slightly enriched soil. Water to establish, or ideally plant in fall then natural rainfall alone. It will tolerate quite a bit of shade as well as root competition but not low shade, high overstay shade is better. . Informal shrub- good year round appearance. Extreme drought adaptation when established. In habitat this shrub is found with Arctostaphylos canescens, viscida, and Rhododendron occidentale and macrophyllum. Overstory is Chamaecyparis lawsoniana, Pseudotsuga, Pinus attentuata, Umbellularia californica. Quercus sp. Cold hardy. Great for wildlife. Seed grown., Oregon native plant
Xera Plants Introduction
We selected this seedling long ago for its vigor, it was culled from a batch of 50 as one of the best and it is. ‘Foxy Red’ is a mounding, low growing shrub that spreads. To 3′ tall x 8′ wide it produces a nearly year round parade of tomato red flowers. The elongated superior foliage is olive green on the upper surface and gray below and comes to sharp point. Fast growing in full sun to light shade. Average unimproved soils are ideal, dig a large hole and soften the soil on the outer edges. Water faithfully, once a week until good new growth commences then water less- once every two weeks/month depending on aridity. Nice looking winter blooming shrub that is ideal planted above rock walls where it can cascade down. Loved by hummingbirds, especially wintering Anna’s who see an out of season nectar source as gold. Mulch after planting- coarse bark, chips, gravel…. Established plants take summer drought without supplemental irrigation. Should be deer resistant. At some point we’ll test it for their consumption. Really nice looking shrub both in foliage and bright flower. May be pruned at any time of the year. Avoid strong subfreezing east wind. Protected site- south or west facing.
Xera Plants Introduction
Grevilleas are interesting in that almost all species will cross and you can end up with some really weird shit. In this instance I selected this mounding evergreen shrub for the vividness of its orange flowers and superior cold hardiness from about 50 others. This cross between G. victorae and G. juniperina has thicker leaves than most cultivars (and seedlings) and that translates directly to improved cold hardiness and they end in a sharp tip. This variety has weathered 10ºF so far and could be hardier. Larger, vivid orange flowers with a style stained melon red that quickly matches the orange of the perianth. (Pouch like petals that reflex when open). To 3′ tall x 8′ wide in 5 years. Full sun to very light shade in average to poor soil. Water weekly after planting and then as growth increases limit it to once a month- a deep soak. Blooms almost continually with a crescendo in late winter/early spring. Loved by hummingbirds, European honeybees, and native hover flies. Easy to grow. Mulch after planting. Its important that Grevilleas become well established by their first winter- this immediately increases cold hardiness. Once established its fairly care free except for occasional pruning. Established shrubs can go through summer without any supplemental water. Fun to grow shrub. Excellent at the Oregon coast, tolerates sandy substrates with additional water. Not bothered by deer. Elk? I have no idea- they will at least step on it so protect. Grevilleas all require good air circulation. Avoid plants that flop or lay on them- not only will it block the sun it can even encourage rot. Site your Grevilleas where they are open and the wind can blow them dry.
Xera Plants Introduction
Abutilon (Callianthe) ‘Nectarine’
One of our very finest Flowering Maple selections. Relatively large pendulous flowers are soft citrus yellow/orange with darker red veining. As this variety blooms out the flowers expand and the petals reflex upward, a very charming look. Vigorous and surprisingly cold hardy Abutilon. To 4′ x 4′ in a season. Rich soil that drains with REGULAR H20. During the growing season Flowering maples very much appreciate at least one application of all purpose organic fertilizer to enhance vigor and blooming. Easy to grow in containers where it will likely perform as a tender annual. In the ground it is different. By the end of winter the plant will look absolutely horrible sticks and maybe a few pieces of tattered dead leaves. The secret to the spring resurrection is to water heavily and consistently until you see new growth. Then you can let the soil dry between irrigation. Loved by Hummingbirds and birds in general. Grows very fast in the correct conditions. Blooms June to October.
Xera Plants Introduction
Low ground cover Germander that is at home in hot sunny aspects in well drained conditions. The fine gray foliage rises to 5″ tall and forms a spreading plant. Beginning in early summer and extending to fall soft purple to lavender clusters of flowers cover the surface of the plant. Though small this plant is a huge hit with pollinators. Full, hot sun and light summer water to establish. Not a fan of heavy soils and sodden conditions In the wild this plant is primarily a resident of rocky sites and hillsides of the Mediterranean. This ever gray perennial is good looking in winter. Foliage is aromatic and has fruity tints to the fragrance. Mix with other smaller rock garden plants or develop a small area that acts as a groundcover. Loathes shade. Good container or trough plant. Grows up to 18″ wide in several years. Pollinator masterpiece. Moderate deer resistance.
One of the boldest species of lily turf that is as tough and adaptable as the rest of the genus. Wide leaves (for this genus) measure about 1″ wide and form rosettes that are staunchly evergreen. The initial rosette measures about 1′ across, in time it increases by stolons as well as enlarging clumps. This species is native to SW Asia and is surprisingly cold hardy. Great year round appearance of foliage. In late summer 2′ thin spikes rise above the leaves and displays soft mauve flowers for several weeks. An added vertical element that is subtle but very pretty. Part shade to shade, avoid hot dry sites. Rich soil and regular irrigation speeds growth and establishment. Adaptable to dry shade when established. Great in year round containers- I have yet to see it blemished by winter weather. Easy to grow, long lived perennial that is pretty and useful. Not bothered by deer- unsure about rabbits but I suspect they would love it. This Liriope has the widest leaves. Clumping. Consistent summer irrigation for the best appearance. Pronounced Leer-EYE- oh-pee.
Erigeron glaucus ‘Bright Lights’
Beach fleabane or beach daisy normally runs in a mauve, to periwinkle vein. This lovely selection turns it up with crystal white daisies and a bold yellow center. Long lived perennial that is very adaptable. To 6″ tall a happy clump will spread to 2′ wide or more. Low and spreading it displays the flowers upright in a mass. This beckons pollinates and they always find this easy going daisy. Full sun, rich to average soil with regular irrigation through the bloom period. This not only keeps the plant verdant it encourage re-bloom which can occur until September. The initial huge show of flowers begins in late May into July. Excellent perennial for the top of a wall where it will happily creep over the edge and follow the contours on the way down. It may be cut back hard after the initial large flush of flowers, this tidies the plant and sets the stage for another big show. Not bothered by deer and often left alone by rabbits. This daisy is most conspicuous in habitat on the cliffs adjacent to the beach. It also perches on sea stacks. Beach fleabane ranges from the Northern Oregon coast south all along the California coast. Mix with other Erigeron glaucus cultivars for depth of contrast- this is when all the flower colors look the most distinct. Very easy to grow and it also absorbs the heat of parking strips with no issues. Cold hardy. Oregon native plant
Eccremocarpus scaber ‘Orange’
Chilean glory vine comes in a host of flower colors. We’ve endeavored to sell them by that category. This orange variety is both a vivid color and the most common for this short lived vine. To 8′ in a season- or taller this light textured vine attaches itself by tendrils. Provide fine support such as a mesh or small diameter trellis. Bloom is on new growth and continues all season. After flowering chain of swollen seed pods appear- leave some on the plant to ripen as this plant will also self sow and the main plant will live for only 3-5 years so you want a replacement. Loved by pollinators but naturally adapted to hummingbirds. Full sun and rich, well drained soil in a protected location. This is a great vine textured, light vine for fence, even chicken coops. Dies back to the ground in normal to colder than normal winters, returns from the base in spring. Lovely vine. Mulch in autumn to protect the base. Chile
Dianthus ‘Georgia Peach Pie’
Wonderful new Dianthus that enchants us with large single flowers of intricate coloring. One inch wide flowers have a pinked edge and the interior of the fragrant flower is a ring of darker pink. On either side of the ring a zone of coral on the center with a ring of very light pink on the exterior- see complex. The clove scented flowers appear from April-July and are showy for weeks. Excellent cut flower that produces long stems and is ideal for bouquets. To 1′ x 1′ forming a slowly spreading evergreen clump. Not bothered by pests or disease. If Dianthus are shy to bloom in our climate a handful of lime in winter is all thats needed. Regular water though bloom time then less required. Excellent combined with other smaller perennials. Enchanting with the chalk pink simultaneous flowers of Aethionema Shrubby rock cress. Evergreen. Flowers are edible and are sweet with a hint of the fragrance. Beautiful Dianthus. Long lived perennial.
Abutilon (Callianthe) ‘Nabob’
Odd name for a wonderful flowering maple. This Abutilon has earned its fame with large deep red/black red pendant flowers for months on end. In one season it will form a substantial sub-shrub and bloom continuously as it grows. Rounded habit to 4’x 3′. Its best home is in containers where you can inspect the intensity of the flower color up close. Each globe shaped flower is 1 1/2″ wide and they occur in a huge display for months. Loved by hummingbirds and pollinators as well. Rich soil with regular irrigation. In spring if the winter has been normal to mild it will often resprout from the base when warm weather returns. Mulch in autumn to protect the base. The early spring appearance is pretty awful the solution is to water, water, water, and add a 1/2 cup of all purpose organic fertilizer. Recovery is rapid as the weather warms. If in a mobile container it may be moved into an unheated garage and watered once a month through winter. Bring out, fertilize and water when all threat of frost has passed. Classic flowering maple.
Cold hardy and very showy Hebe that is an excellent small scale ground cover. To just inches high it expands over time to up to 4′ wide. The gray evergreen foliage is handsome year round. In early summer the tips of the plant are ensconced in violet- blue colored flowers. This showy display draws pollinators and butterflies. One of the showiest of the very cold hardy varieties. Takes temperatures below 10ºF with no damage. Excellent on slopes. Expanding branches can root where they touch the ground, making this spreader excellent for erosion control. It also grows with such density to block weeds. Very easy to grow. Mix with perennials and in-between shrubs in full sun to very light shade. Light CONSISTENT summer irrigation. The small gray leaves line the black stems for more exquisite detail. Excellent at the top of a wall where it will trail and follow the contours exactly. Moderate deer resistance.
Abutilon (Callianthe) megapotamicum (a) ‘Red’
Everything about this form of hardy flowering maple is identical to the species except the molten red flowers with deeper veins shot through. The 2″ pendant flowers appear from May to October on a large growing sub-shrub. To 6′ in a single season It makes rapid growth as temperature rise above 70ºF. Full sun, in a protected location in rich soil with regular summer irrigation. Abutilons look absolutely horrific in spring even after a normal winter. Expect this. The solution is to water, water, water especially as the temperatures rise. It blooms on new wood and flowers are continuous as the shrub grows. Mostly deciduous but it can be evergreen at the coast or in protected places in mild winters. Loved by hummingbirds who are lured by the lurid red flowers filled with nectar. Cut back by 1/2 after all danger of frost has passed. Supply a handful of all organic fertilizer and water faithfully. Excellent performance at the Oregon coast. Inland it is best with the protection of a shrub covering its roots so that the soil does not freeze. In this situations it can live even thrive for many many years. Mulch with compost. Native to the mountains of Brazil. Root hardy to about 10ºF. Long lithe stems can be woven through a fence or a lattice.
Oxalis oregana ‘White Flower Form’
There are quite a few selection off Redwood Sorrel or Oregon sorrel. This is the most common light green leaved form that you see carpeting shady dells and tree rootwells in the deepest shade. To 8″ tall and spreading vigorously by underground stolons. Clear white flowers in mid to late spring. Edible. Very simple plant to grow in part shade to shade. It will even thrive on an open north exposure. The soft foliage is semi-evergreen and has a great rebirth in spring. Not bothered by pests or deer. Spreads to several feet wide in rich soil high in humus. Do not plant with smaller delicate neighbors this plant will easily swamp them. Avoid full sun and compacted soils. Established plants can get by the summer with minimal to no irrigation. Oregon native plant.
We’ve been attempting to hybridize Grevilleas specifically, and that has proven to be difficult. What I rely on then are open pollinated hybrids – all Grevillea species can cross, pollinated by European honeybees in my garden they almost all set seed. This is seed from a hybrid between Grevillea victorae x Grevillea juniperina ‘Gold’. I sowed a bunch of seed and this seedling stands out as superior to the other seedlings and to many other Grevilleas that we grow. This is an upright growing and then spending evergreen shrub with distinctive small grass green wedge shaped leaves. The flowers are very large for a hybrid and the perianth is a soft citrus pastel orange. The style or pollen presenter begins life after opening with a red/melon color as it ages the style changes to light yellow from the tip down. The base of the style nearest the perianth remains dark melon red. Very heavy blooming selection. Flowers appear January-July and on older plants year round. The large clusters of un opened buds are shaded light pink before maturing. Upright growing then spreading laterally with age. To 4′ tall and 6′ wide. All Grevilleas are a beacon to Hummingbirds and all birds as is this cultivar. Full sun in average, un-amended soil. Dig a very large hole and water weekly until you see good new growth then taper to once a month. I’m very proud to offer this seedling, it is a vast improvement on other Grevilleas with similar size flowers- this one beats them all. Best in a warm, protected location.
Xera Plants Introduction
Tan bark oak or Tan Oak is native to the SW corner of Oregon south into the mountains of southern Califiornia. The large convex leaves emerge clad in gray fur as this wears off it reveals a mature deep green with an underside of silver. Moderately fast growing evergreen tree to 45′ tall x 25′ wide in 30 years. Grows on average 2′-4′ per year when young. This close relative of Oaks produces acorns that are light tan and born out of an indumentum covered prickly cup. In Oregon this tree mostly of mountains can be found most extensively from Douglas and Coos County south to the coastal border. It is found in the higher elevations of the mountains of northern California where quite a bit of heavy wet snow occurs. This tree will bend in snow and ice and it will not break. Conical and spreading crown. Tan Oak which was harvested in the 19th and early 20th century for the collection of commercial tannins. Full sun, it grows well but is slower and a bit spindly as an understory tree. The furrowed bark is dark brown to black. Its range is almost the same in Oregon as Canyon live oak (Quercus chrysolepis) and cold hardiness is equivalent too, hardy just below 0ºF. Wonderful, stately, native evergreen shade tree. Ours are raised from acorns collected at the northern extent of its range in Douglas County. Oregon native plant.
Hebe pimelioides ‘Quicksilver’
Fascinating New Zealand Hebe that is native to higher montane areas and is therefore very hardy to cold. Many arch black stems cradle rows of symmetrical small gray foliage. The color effect is more machine than plant and this arching shrub gains density by shearing the tips after flowering has ended in June. 2″ spikes support rows of violet blue flowers that fade to white in the oldest blooms. This shrub is best in containers or new gardens. It tends not to age well after 5 or so it begins to look unkempt. You can stave this off with pruning- prune just under the base of the lowest flower spike in July. Excellent new garden or rock garden plant for fine silvery texture and contrast with black stems. It truly shine in winter containers where it looks its best. To 14″ tall x 16″ wide forming somewhat of an anvil shape. Consistent summer water during hot spells. Cold hardy to the single digits.
This is a relatively cold hardy and spectacular bottlebrush. Very upright growth on a vertical growing plant with distinctly blue leaves. In late spring soft yellow thick bottle brush flowers appear in a massive display. Hummingbirds and people come running. The glowing flower color set against a blue backdrop is sublime. Full sun (no shade, don’t even try) in a warm, protected location such as a south facing wall or fence. Moderately fast growing in the ground to 12′ tall and 4′ wide in 7 years. It can suffer considerable damage in our coldest winters, but established plants have recovered from temperatures below 10ºF. Blooms on wood from the previous year. Prune if needed after blooming has ended. Rows of button shaped woody seed capsule follow and persist for several years. Spectacular and easy at the coast. Aromatic foliage has some deer resistance. Protect containerized plants from temperatures below 20ºF. Blooms well in a container. Tasmania. Water to establish then occasionally in summer. Avoid strong subfreezing wind.
Rosmarinus officinale (Salvia) ‘Mozart’
The blue flowers of the common and loved herb rosemary rivals that of Ceanothus and Lithodora. That is on certain varieties. Bloom typically begins in December and peaks in early spring continuing until late spring on the best varieties. This is the best variety for blue flowers. The obvious Salvia flowers on ‘Mozart’ are thick on the stems and are entirely dark blue- no interior dots of white or white splotches. Full sun and water to establish in average soil. Extremely drought adapted when established. This strongly arching shrub goes up to about 30″ and spreads to 4′ wide. Hillsides, the top of rock walls, containers subjected to reflected heat. Pork roast. Very good culinary use/taste for this plant. Hardy to about 5ºF. Good drainage improves cold hardiness. Tolerates the hottest places with no stress. Aromatic waxy resin will attach to your fingers. Blooms on wood from the previous season. Prune or harvest when needed after blooming has ended. Some deer resistance. Extraordinarily drought adapted. Great performance at the Oregon coast.
Helleborus x sternii ‘Variegata’
The O’Byrnes gave us this strain of the variegated form of Helleborus x sternii. Inheriting cold tolerance from H. corsica and nifty, thick palmate leaves from the more tender H. lividus .The result is a tough plant with green cupped flowers stained rose on the outside of the bell. The flowers remain effective for several months. Not quite as long as the straight H. x sternii, but a relatively long time. A shrubby species with large evergreen leaves. They are heavily speckled with cream dots with an underside to the leaves and the stems tinted pink. The palmate leaves become large and arching. Full sun with more frequent irrigation to full shade with less. To 2′ x 2′. Deer and possibly rabbit resistant. The rough leaves resist weather. Site as you would for a small shrub. It is elegant with other woodlanders or can be grown with drought tolerant to low water plants even in full sun. Flower bend over enshrouded in a cup shape that protects the pollen from rain and the vagaries of winter weather. Blooms January with flowers effective for three months. Great, sophisticated but tough plant for rural areas. May be afflicted with aphids in late spring. Hose those off or do not look closely.
Ceanothus gloriosus ‘Anchor Bay’
A very good looking mounded, evergreen shrub that is best appreciated in milder gardens. In colder gardens provide a warm protected site. The small holly-like leaves are mat green and good looking year round. This moderately fast growing shrub at first spreads out and then with time mounds up. To 30″ tall by 4′ wide in 6 years. Dense growth suppresses weeds. In Apri/May for 3 weeks button shaped flower cluster are pale sky blue and appear on wood from the previous year. Prune, if needed after bloom has ended. This is seldom necessary. Consistent summer water for the first season then none in subsequent years. Excellent adaptation to the Oregon coast. Cold hardy to 8º-10ºF briefly. Very good performance in hot sunny hell strips. Accepts part shade (at the expense of bloom) and poor soils. Somewhat formal in appearance it avoids the brush pile look with dense, closely layered leaves. Not as palatable to deer. Good appearance year round.
Rosa x banksiae ‘Purezza’
Large climbing rose that is a wonderful hybrid with the white Lady Banks Rose. This plant has larger flowers sweetly fragrant of violets in a huge display in late spring. Unlike Lady Banks Rose this hybrid bears smalle double white flowersr that continue until autumn. Very fast growing semi-evergreen climbing rose that has little to no thorns. To 15′ tall it is is ideal for a large pergola or even sent to climb a substantial tree. Large plant provide strong support. Not bothered by pests or disease this is a romantic easy to grow. Arches, fences. Hardier to cold than Lady Banks but just as adaptable to hot situations in full sun to very light shade in rich amended soil with regular summer water. Rich soil and water will produce better summer re-bloom. Blooms on wood from the previous season as well as new wood. Prune after the first large flush of flowers. This is a big rose prepare accordingly. Not bothered by blackspot. This rose is on its own roots.
Ceanothus x ‘Peg’s Pride’
Beautiful ground cover Ceanothus that bears dense sky blue flowers in a vivid carpet in April to May. To 2′ tall and mounding it stretches out to 8′ wide. The dense evergreen growth blocks weeds effectively. Very good on steep slopes. Loved by all pollinators and especially important to native bees. This is one of the cold hardier ground cover hybrids taking 5ºF with no issue. Excellent combined with Cistus and Halimiums. Fast growing to its ultimate size. Best in full sun but will tolerate light shade with sparser bloom. Regular water for the first season to establish then none in subsequent years. Supremely drought adapted. Very good at the Oregon coast and adaptable to sandy substrates.Mid green round leaves are semi gloss and handsome year round. Spectacular in bloom. Plant on 4′ centers for a large evergreen groundcover.
Fantastic early spring perennial that possesses arguably the bluest flowers in the genus. Large clusters of reverberating blue appear in late February and are showy until late April. The smaller than normal leaves posess the spots that makes this a classic Pulmonaria. To 2′ x 2′ and arching. Very easy to grow hardy perennial for part shade to full sun in rich, moisture retentive soil with regular summer irrigation. A substantial patch of this perennial is a sea of blue. Not bothered by slugs or other pests in general. Mixes ideally with white or yellow flowered Hellebores or grouped with hardy winter Cyclamen coum. Easy to grow and long lived. If you like blue, this prolific bloomer is the Pulmonaria for you.
Arctostaphylos standfordiana ‘Sonoma’
Wonderful smaller Manzanita with clusters of vivid pink flowers, grass green foliage, and deep red/mahogany stems and bark. To 5′ x 5′ in several years. In time it makes a mounding form. The large clusters of pink flowers in February and March hang gracefully like clumps of grapes. Easy to grow for a low hedge or focal point. This is a great shrub to begin spring. Full sun and average, un – amended soil with water to establish then absolutely none after that. Great shrub for baking hot locations and even compacted soil. Both the size of the leaves and flowers which are large makes one think that this would be a very large almost arboreal cultivar- but no. Moderately slow growing. Loved by hummingbirds and native bees to which this is a very important plant. The flowers are slightly less hot pink than A. b ‘Louis Edmonds’. A very very pretty shrub. Extraordinarily drought adapted. No summer water.
Arctostaphylos columbiana ‘Pacific Coast’
This is a compact, dense growing form of Hairy Manzanita from the city of Manzanita on the coast. These are Greg’s collections. He chose several forms that had nice foliage, foliage color, habit, and resistance to disease. This form is one of the most compact of the three. Slightly smaller leaves are born densely on a more reserved growing plant. In late winter to spring clusters of white flowers followed by drupes that turn distinctly red. Inland forms of this Manzanita have maroon to russet berries so this is a distinct difference. Beautiful dark, glossy maroon bark as for the species. To 6′ x 6′ in 7 years. Adapted to average to poor soils which will allow it to grow at a more reserved rate. Arctostaphylos columbiana reacts to richer soils, even clay soils with exuberant growth. Best in our native soils that are unimproved. Dig a large hole and provide regular water until you see good new growth then taper off. In subsequent years only what falls from the sky. Arctostaphylos columbiana (Hairy Manzanita) is a proto species one of the first and it is the most widespread Manzanita in Oregon and Washington. Genetically it dominates and most of Calfiornia’s northern species are derived from ancient Hairy Manzanita. Provide full sun and good air circulation. Excellent underplanted with native annuals and Sedums. Good looking siver/ gray foliage year round. Extraordinarily drought adapted. Associated plants with the coastal species are Vaccinium ovatum, Pinus contorta ssp. contorta Garrya elliptica, Baccharis pilularis and Salal (Gaultheria shallon). Often found with Festuca rubra on stabilized sand dunes. Oregon native plant
Xera Plants Introduction
Chamisso Sedge is a wonderful, common and extremely widespread sedge native to the W/NW parts of the US. Upright growing evergreen clumper to 10″ tall x 10″ wide in a season. The complex flowers are brown awns clustered in orbs at the top of very straight 20″ stems. Adaptable to a wide range of conditions from wet riparian zones to drier upland sites. In the wild it accompanies such perennials as Delphinium trollifolium, to Iris tenax. Good looking year round with just a slightly beat up look after the hardest winters. Spreads moderately fast in rich to average soil. Better year round appearance with a light application of compost. Excellent in a Willamette Valley meadow that is wet in winter and bone dry in summer. Each clump is dense enough to inhibit weed competition. Spreads very lightly by seed. Clumps that lose their luster in summer drought can be irrigated. Good garden performance. Great massed plant on 1′ centers. Oregon native plant.
An exciting shrub/small tree with paddle shaped blue evergreen phyllodes for foliage and in late winter to early spring a massive display of luminous yellow flowers. I’ve always loved Australian wattles so it was with great excitement that we decided to grow this striking plant. Moderately fast growing to 16′ tall and 8′ wide forming either multiple or a single trunk. The bark is chocolate brown and smooth. Very few Australian Acacias will thrive in Portland, its just about 5 degrees too cold in our coldest years. This one is different, (a few species will live for 4-6 years before they finally succumb to Jack Frost. Acacia pravissima etc.) This, however, is the cold hardiest that we have grown. It is hardy to just below 10ºF for brief stints- good enough for long term survival. This is a rare limited endemic to the high mountains of New South Wales but is popular as a garden subject the world over. The small, fluffy, balls of electric yellow flowers foam among the blue leaves – incredibly pretty. Full sun and a protected location – against a south facing wall is ideal for a very pretty fun to grow tree. Once fully open the flowering stems may be cut for long lasting bouquets. Blooms on wood from the previous season, prune if needed after flowering has ended. Light consistent water to establish . Not fussy about soils and happiest in full, all day sun. Protect from subfreezing east wind. Bloom time is concurrent with several earlier Ceanothus (‘Blue Jeans’, ‘Dark Star’, ‘Concha’) and creates a vivid early spring yellow and blue display not soon to be forgotten. Drought adapted when established. Not bothered by deer/elk- not entirely sure about rabbits- if they are profuse in your neighborhood it wouldn’t hurt to protect the plant with chicken wire when young. Beautiful year round and spectacular in bloom. AKA Blue Bush.
Cider gum. This is a very successful Eucalyptus in Western Oregon. Native to the high central plateau in Tasmania it forms a handsome tree to 35′ tall and 20′ wide in 10 years. As with many Eucalypts this species begins with very different juvenile foliage that is bright blue/gray with rounded leaves. After several years of vigorous growth foliage morphs to longer, greener leaves with a somewhat weeping habit. In order to retain juvenile foliage for cut material let the tree establish well for a year or two. In March to April 15 the whole tree may be coppiced to the ground. Re-growth is rapid with the arrival of truly warm weather and light applications of water. Left strictly alone Cider Gum becomes large and stately. One of its most striking features is blue/gray stems which are visible at quite a distance. Mature trees have clumps of foliage at the end of longer stems. A distinct look. Very fast growing in youth- 3′-5’per year. Growth slows with maturity but it achieves tree like stature very fast. Excellent in snow and ice. Cold hardy to about 5ºF – provide a warm microclimate in cold rural gardens. Excellent performance in urban areas. Not as messy of a Eucalyptus as some. As the tree matures the trunk exfoliates to smooth gray/tan with pink mottling. Excellent performance on the Oregon coast. Not bothered by deer or elk. A very pretty tree in a short amount of time. Drought adapted with age.
Monardella villosa ‘Russian River’
Incredibly long blooming native sub-shrub with clouds of fragrant purple flowers for all of summer into autumn. To 2′ x 2′ forming a semi-woody base. The aromatic round leaves cup the flower buds as the stems elongate. Loved by all native pollinators. A wonderful plant in the mint family that is very easy to grow and long lived for this genus. This selection sports slightly darker purple and longer blooming flowers. Found from Douglas County, Oregon south throughout California. Freezes back in very cold winters but sprouts quickly with warm weather in spring and commences bloom quickly. Great as a mass planting and ideal in a meadow. Also, adaptable to rock gardens and indeed thats where you find it in the wild- among gravel, rocks, and boulders. Mix with other long blooming native perennials such as Erigeron glaucus (sp & cvs) and among California fescue (Festuca californica). A very climate adapted plant. Cut back spent flowers and more will follow. Nice cut flower. Very long blooming. Light summer water to very little when established. Some deer resistance. AKA Showy coyote mint. Oregon native plant.
Eryngium proteiflorum MX
This is a spectacular plant and Brandon collected the seed outside of Mexico City- at a very high elevation. Still we are not completely sure of its ultimate hardiness so I’m going to guess. Based on other Mexican and S. American Eryngium and considering this is a widely spread species I’ll say its good in rich amended soil that drains to about 10ºF. That is somewhat irrelevant as the flower on this member of the Apiaceae (Carrot family)is phenomenal. In May-August HUGER 6″ wide flowers with a protruding central cone are metallic silver and sage green Unbelievable. Full sun to light shade in a protected location. Worth protecting in a pot as it makes a stellar container plant. The unearthly flowers are held on vertical stems to 3′-4′. As a cut flower it is a wet dream, lasting weeks and drying too. Kind of prickly a low rosette of serrated evergreen leaves is permanent. Cut away the spent flower stalk when it fades and you tire of it. Light, consistent water. Fantastic. Thank you to our great employee Brandon for capturing the seed.
Baccharis pilularis ssp. consanguinea
This is the Willamette Valley form of coyote brush (bush)- also known as chaparral broom. A relatively short lived evergreen shrub in the aster family. Indeed this form blooms in autumn through winter with small brushes of white plumed flowers on female plants. Smaller yellow flowers on males. Typical of the steepest cliffs abutting the ocean and in the Willamette Valley it populates recent road cuts and fire zones. Often it will be seen all alone in the center of a Willamette Valley field. Native inland from northern Marion county to Douglas county. Very fast growing and drought adapted daisy bush for rough sites and poor soil. Improved soil will yield an enormous shrub so its difficult to pin point an exact size but everything from 4′ tall in poor soil with no summer water to 12′ x 12′ in rich soil with irrigation. I suggest no irrigation after planting. Excellent fodder for insects and birds. It may be pruned heavily in spring and will quickly regenerate. Foliage is deep glossy green but fine textured. Not bothered by deer. Excellent native companion for Manzanita, Grevilleas. VERY EASY to grow. average life span 10 years. Good instant plant for a native garden, but not long term. Native from N. Oregon coast south to Baja California. A prominent component of the California beach chaparral and on the Oregon coast as well. Common associated plants on the coast are Salal (Gaultheria shallon) and Mahonia nervosa. In the Willamette Valley its primary role has been ursurped by Scot’s Broom. Too bad. Oregon native plant.
Carex tumulicola ‘Willamette Gold’
Wow, when nature smiles on you then you need to take advantage. We found this stable variant of our locally native foothill sedge that is pure gold. As for the species a clumper that forms trailing 12″ foliage. The tight clumps keep to themselves and do not seed or run. Brilliant color all season long in average to enriched soil in full sun to light shade. Water consistently through summer for the best, consistent color. Attending flowers are on wiry straight stems with buff flowers in late spring to early summer. Mass for a much more drought adapted and vivid effect as Hakenochloa- Japanese forest grass. Easy to grow climate adapted native sedge. This is from a seedling batch of Willamette Valley native seed. Tough and good looking all the time. Evergreen- ever gold. To 6″ tall and 1′ wide. Plant on 1′ centers for a massed effect. Excellent in concert with other drought adapted natives, Manzanita etc. A great robust plant. Oregon native plant.
Xera Plants Introduction
Honey swamp myrtle hails from wet locations in Tasmania. Its a tender shrub inland but it thrives in zone 9 on the Oregon coast. A fur clad fine leaved shrub that is a true myrtle. In April-May the whole plant is home to stamen dominated purple bottlebrush flowers. Exquisite. Very easy container subject that can be moved to a protected place if severe cold (below 20ºF) threatens. Excellent shrub for sandy substrates though it takes well to heavy clay too. Light consistent summer water. To 5′ tall by 2′ wide in 7 years. Great plant for hummingbirds and butterflies. Inland we have yet to test the cold hardiness in the ground. It should easily take 15ºF but probably not lower. Evergreen foliage is fragrant when disturbed. Good deer and rabbit resistance. Absolutely titillating in bloom. Native to mid and high elevations of Tasmania. Seed grown.
Arctostaphylos manzanita ‘Dr. Hurd’
An old and venerable cultivar of this species. This small tree achieves 12′-15′ with great age forming a showy and jaw dropping evergreen. Pale sea foam green/ grayish foliage is large and very circular giving this tree a billowing appearance. In winter white tinted pink flowers erupt from all the branch tips. These morph into large russet berries consumed by birds. The mahogany twisting, muscular bark is the most outstanding feature. Fast growing in youth (2′-5′) per year when excited. Give this dry loving shrub EXCELLENT air circulation in an open exposure. It can be afflicted by black spot in wetter than normal springs. ‘Austin Griffiths’ which is 1/2 this cultivar is more resistant to black spot. In time you can remove the lower shaded branches to show the trunk and improve air circulation as well as general good looks. Tall and often half as wide. Locate in a hot sunny place and water to establish then set it free. Very striking tree that is best planted as a smaller plant. Large specimens will NOT live as long and will be more difficult to establish.
Hairy Honeysuckle or wild pink honeysuckle is a common vine in the western part of our state. Ranging rom S. British Columbia to California. This sprawling and twining plant is most associated with the cover under white oak woodlands. This vine can crawl to impressive heights into trees. As a child near Eugene this grew extensively on our property. It would climb pole sized trees and I would strip the winding canes off the trees and use them as a trellis for annual vines. The strong wood lasted 10 years or more. It derives its name from the conspicuous hairs on the leaves. At terminal ends of the branches soft pink curly flowers appear in cymes from June to September. These are followed by brilliant red berries that are food for birds. It has no fragrance. Excellent plant for stabilizing banks and hillsides where its incredible tenacity and drought tolerance is an advantage. Never a tidy plant this vine can be sent up a trellis or large tree. Water to establish then set it free. This honeysuckle can be afflicted with aphids early in the season but I’ve never seen it actually inhibit the plant. Just make sure not to look to closely at the plant in May-June. Evergreen to semi-evergreen with round leaves that surrounding the stem nearest the ends just before the flowers appear. Best in wild areas.- for some it can lack the sophistication of our other native honeysuckle Lonicera ciliosa. and is not as immediately beautiful. In habitat it consorts with Oregon White Oak (Quercus garryana) Poison Oak (Toxicodendron diversifolia) and Creeping snowberry (Symphoricarpos albus). Often found clambering up steep rocky slopes in dry woods. Oregon native plant.
Western sword fern is one of the most ubiquitous plants on the west side of the Cascades. In many forests in the Coast Range and Cascade foothills it is the sole understory plant. Western sword fern is a large species with long arching fronds. Adaptable to a host of situations. Often self sown spore will show up in the oddest places. I’ve seen it as an epiphyte and even self sown into hot concrete steps. In rich, acidic soil this evergreen fern soar- provided soils rich in humus, organic matter and protected from direct sun with consistent access to water. Very well adapted to our winter wet/ summer dry climate- it will cruise through dry summers unscathed. In the garden it does useful duty in the toughest, dry, shadiest sites. Along with Cast Iron Plant (Aspidistra elatior) and Ophiopogon (Lily turf) it is one of the best dry shade inhabitants. As an understory component it is often accompanied by Cascades Mahonia (Mahonia nervosa), Inside-out-flower, (Vancouveria hexandra), and Pacific Blackberry (Rubus ursinus). To 4′ x 4′ in ideal situations. Though it is evergreen western sword fern does go through a transitional period before new croziers unfurl in spring. The 3′ long fronds begin to lie flat on the ground by winter. This is the time to remove tired, old leaves. and make way for fresh, new, unfurling foliage. Though very tough western sword fern does look its best with consistent light water. Supremely deer and rabbit resistant. Long lived and not a slow grower. Oregon native plant.
Hebe ‘Pink Paradise’
Excellent symmetrical evergreen foliage on a dense dome shaped shrub. The sea green/blue cupped foliage surrounds deep mahogany stems. To 2′ tall by 3′ wide forming a moderately fast spreading plant. In spring and often again in late summer a parade of sparkling pink flowers. They look wonderful agains the foliage. Easy to grow lovely shrub with a year round handsome interest. Excellent performance at the Oregon coast. Good cold hardiness into the lower teens or lower for brief periods. Light consistent summer water in full sun to very light shade. Protect from subfreezing wind which won’t kill it but can make this Hebe unhappy. Good long term performance in gardens and a welcome flower color in a genus replete with purple, blue, and white. Nice looking shrub at all times. Best in enriched soil. Remove the first round of flowers to better view the second late summer display.
Clinopodium (Satureja) douglasii
Yerba buena is a fine trailing herb native to southeast Alaska south into northern California. Its a common scrambling component of woods and forest margins. The round slightly scalloped leaves emit a sweet herb/mint fragrance that reminds me of childhood and they line trailing stems. This 4″ tall by 2′ wide perennial is commonly found among shrubs and clumping grasses as well as perennials. It can be found in the wild with such plants as Vancouveria hexandra (Inside out flower) and Whipplea modesta (Whipple Vine). In late spring to early summer barely conspicuous tiny white snapdragon flowers appear in the leaf axils. Evergreen. Often the leaves turn maroon red in cold weather. The sturdy semi-woody stems root where they attach to the ground and it may be used as a deer resistant small scale ground cover for stabilizing smaller scale slopes. This member of the mint family can be used to flavor iced tea or any cold drink. Shade to part shade in average to slightly enriched soil. Combines well with clumping grasses and smaller scale shrubs such as Symphoricarpos (Snow Berry). Good in containers as well. Yerba buena (the good herb). Excellent native pollinator perennial in the mint family. Oregon native plant.
Hebe x ‘Thunderpaws’
One of Andy’s excellent seedlings this dapper shrub is ensconced in violet blue flowers fading to white on a raceme. He and his son Graham agreed on this great name. In full, massive bloom this is one impressive small evergreen shrub. To 2′ x 3′ in 5 years in enhanced soil with drainage. Avoid frost pockets. Locate in the warm part of your garden, Excellent performance at the Oregon coast. Blooms heavily from late spring to mid summer. Then it is a clean symmetrical evergreen shrub Locate out of the path of subfreezing wind. Light, consistent summer water. Good landscape/garden shrub. Loved by butterflies and several different bees. Mulch after planting. Very heavy bloom is showy and is great massed in odd numbers. Mix with Carex pansa ‘Chisai’.New growth that follows bloom is tinted red before settling to deep green. Impressive new Hebe introduction. The spectacular show of flowers begins in June and lasts six weeks. Exceptional.
Xera Plants Introduction via Andy Stockton.
Pacific Reed grass is a large and stately grass that is found close to the coast/ beach. A tall growing species with large flat green foliage and tall flowers that are at first green and then age to straw in summer. To 3′ tall on average, this plant can even perform as an epiphyte as is sometimes seen in forests adjacent to the beach. Spreads to form large clumps that are staunchly evergreen. Native from S. Alaska to N. California. This makes a wonderful casual plant with stiffly upright flower spikes. To 3′ wide and clumping. Average to amended soil, adaptable to clay soils. This is a great first line grass at the beach. It endures salt spray and poor soils. Easy to grow native grass for rough areas, meadows, forest verges. Full sun to quite a bit of shade. It may be cut back hard in the early spring, but appearance is very stable throughout the year. Deer resistant. Very easy to grow. Light consistent water inland, but drought adapted at the coast. Associated plants in the wild are Polypodium scopulorum, Picea sitchensis, Gaultheria shallon (Salal). One of our best native evergreen grasses for our gardens. Oregon native plant.
Hebe youngii ‘Carl Teschner’
A sparkling little groundcover Hebe with emerald green leaves on trailing black stems and clouds of violet blue flowers in early summer. to 8″ tall spreading to 4′ wide. It covers the ground very densely. It may be used as a small scale ground cover but never more than 4′ x 4′ square feet. Rich to average soil with consistent light water though summer. Cold hardy below 10ºF. Very easy to grow and handsome plant. Hummingbird and Butterflies adore the flowers. Excellent rock garden subject. Very good performance at the coast. Nice trough plant. Good looking year round. Avoid hot wet soils and compacted droughty places. Ideally sited on a slight slope. Stems will eventually root where they touch. Combine with Penstemon pinifolius ‘Mersea Yellow’. New Zealand.
Fragaria virginiana var. platypetala ‘Mt. St. Helens’
Broadleaved strawberry or mountain strawberry is a widespread native species with large white flowers in spring that turn to small delicious red fruits in June. A low spreading perennial that also spreads liberally by runners. This tendency ramps up in richer conditions. This tough native form was found by our employee Brandon at Mt. St. Helens. This clone shows impressive vigor and is useful in a number of ways. A tough species that naturally thrives in clay soils (and clay strawberry pots). It competes admirably with grass and is best between native clumpers. Associated plants in the Willamette Valley are Dichelostemma congestum, Carex tumulicola , Lathyrus nevadensis, and Calochortus tolmiei. Mostly evergreen with many bright red leaves in winter but leaves remain present in all but the coldest situations. In the garden give it rich to average soil and regular irrigation to establish. This variety has enough summer drought adaptation that it will grow sufficiently with little summer water. Cold hardy, tough little plants. Bears one crop of fruit per year. Rescue them from snails and ants. Widespread throughout the region. On the west side it is found everywhere from oak savannas to alpine meadows. In the eastern part of the state it is primarily in the mountains in partly shaded zones where there is adequate moisture. Each plant spreads to about 6″ across and runners expand out more than a foot from that. Oregon native plant.
Xera Plants Introduction
Phacelia heterophylla ssp. virgata
The most sought after plant for native bees is Varied leaf Phacelia. For anyone who has hiked and camped in Oregon you are likely already familiar with this silvery plant. The divided and rounded laves are clad in silver fur and the leaves are the highlight of this widespread perennial. The flower which shows great promise as it rises from the cool leaves. It opens and then unfurls and you expect a purple or even red flower but no disappointly- dingy off white is what unfurls. Either way its a pollinator paradise. Size is dependent on the fertility of the soil. Often you see this plant in its early rosette forms along just about any path in the state. Western Oregon to Eastern Oregon this widespread plant is specific to our native pollinators. To 18″-3′ (in really rich soil). Short lived Oregon native perennial. About 3-5 years. Reliably reseeds. Seedlings are easy to spot as they mimic the parent plant. Full sun to a considerable amount of woodland shade. Associated plants in habitat are Sword ferns (Polystichum minutum) and Vancouveria hexandra. Moderately deer resistant. Native in the Portland city limits. Oregon native plant.
Hebe ‘Blue Mist’
This genus may soon be changed to Veronica. We still list it as Hebe because that is how it is distinctly known in the PNW. This is a good, reliable Hebe (yeah, those exist) with profuse flowers, a dense, layered habit and good looks year round. To 30″ tall and as wide and progressively wider in fat conditions. Plan for this. In May-July a long display of many spikes of flowers they protrude through the waxy forest green foliage. Profuse. The flower buds and initially open flowers are blue and proceed to light blue then white – the mist. This multicolored effect is delightful. Attractive to bees and bumbles and especially butterflies. Full sun to very light shade – successful under a very high tree canopy with bright conditions. Excellent specimen plant with reliable cold hardiness to 10ºF. Very well adapted to the beach. Regular irrigation and a layer of mulch annually. Combine with Bupleurum fruticosum and Lavandula x angustifolia ‘Purity’. We grew this many years ago and have brought it back. Welcome back. An old favorite.
South African Buddleia that we are not concerned about escape, We’ve had this plant on our propagation hill for 15+ years, and there is even a rich stock bed right beside NEVER had a single seedling. Kind of wish I would. Thin tapered gray leaves are pure white underneath and along the stems. This downy appearance reads as light gray from a distance. Forms a rounded shrub to about 6′ tall x 4′ wide in 4 years. Blooms on wood from the previous year (important)- restrict pruning to directly after you are sick of the flowers. Large clusters of off white faintly fragrant flowers appear in late spring and remain in bloom to August, sometimes longer. Moderately fast growing evergreen for excellently drained soils to rich soils in full sun. I would err on the side of poor soil, its a tough shrub with great drought tolerance. Two ideal companions to our stock plant are Bupleurum fruticosum and Grevillea australis. Not only does it look good this 1/2 gravel 1/2 clay substrate is kind of rough and all three thrive. You may cut back very hard to refresh/resize- May skip a year of bloom but its a fantastic evergreen gray foliage plant on those merits. High deer resistance. Drought adapted and cold hardy. We’ve never irrigated ours. Pretty shrub for texture. Nice transitional shrub with Ozothamnus or Grevilleas and even Manzanitas.
Lavandula x angustifolia ‘Purity’
We asked the man who knows lavender the best which white Lavender did he recommend? And he fired this off the top of his head and then brought one for us- Thank you Andy Van Helvingen. A REALLY stunning plant. Compact with many CLEAR WHITE flowers in dense clusters at the end of strong straight stems. The plant is compact and grows that way – much slower. To 16″ x 18″ with bloom spikes above. Flowers early June to August. A charming plant that does not cling to discolored brown flowers instead they just kind of melt away so it does have an extra pristine appearance at all time. Shear spent blooms to their base to encourage a more dense and floriferous shrublet in the future. Wonderfully aromatic hybrid with english Lavender. Moderate deer resistance. This would combine in a perfect way with pink and blue flowered varieties- ‘Hidcote’. Avoid planting closely with L. x intermedia, cause those will flop and smother this little gem. Great for small hedges, rock gardens, and herb knots. Pungent for drying, potpourri. Full sun and rich to average soil with reasonable drainage. Not good in shade. Lavenders also require very good air circulation- plant accordingly. Average life span 5-7 years, Light summer water.
Penstemon pinifolius ‘Mersea Yellow’
Pine leaved Penstemons are great, long lived evergreen perennials in our climate. They decorate rock gardens and rock walls in the most common color which is orange. This is a striking departure. Lemon yellow tubular flowers appear in late May and continue to July. The foliage is what you might expect small needle like leaves cover winding stems. You may remove the spent flowers from the first round, give it a soak and you might get more flowers. Either way you have saved yourself a chore in the future. Full sun to the very lightest shade (at the expense of blooming). Rich, well amended soil and regular summer water through its bloom cycle- then you may back off. Evergreen small trailing shrublet. To 6″ x 12″ wide and 9″ tall in bloom. The flowers on this species will always point in the same direction which is charming. Moderate deer resistance. Combine with Penstemon heterophyllus ‘Electric Blue’ and Erigeron x ‘Wayne Roderick’ for similar cultural requirements and simultaneous bloom time. Excellent in troughs, permanent planters. This species is native to the mountains of New Mexico. Sunny yellow flowers.
Yerba de Selva or whipple vine, a wonderful small scale evergreen native ground cover. Related to Hydrangeas but this trailer is actually very droughtadapted.e In late spring clouds of small white flowers , Scrambling plant to about 8″ tall and 2′ wide. Full sun to considerable shade. From Portland south this is a common understory component of the herb field. It grew happily in our back 40 where I grew up. There it made pretty scrambling patches between Vancouveria, snow berry and hairy honeysuckle. Often you would see our native columbine ( Aquilegia formosa) as an associate. Its very drought adapted when established but it improves with a few soaks over summer- never perpetually wet and never hot and wet. Otherwise an easy native that should be grown a lot more. For use as a small scale ground cover plant on 10″ centers. It will also gracefully trail over rockeries and walls. Butterflies adore the flowers. Competes well with invasives. Some deer resistance. It may be cut back in early spring to refresh. Once native in the Portland city limits. This is a great native understory for Arctostaphylos, which is frequently seen in the wild. Oregon native plant.
Our native Sulphur Buckwheat that is among the best for general garden culture in our climate. This ubiquitous creeping plant of alpine areas of Oregon celebrates spring with umbels of (sulphur) yellow flowers on long stalks. The low and spreading rosette of leaves are thick green on top with silver indumentum on the reverse. Full sun in fast draining conditions- ideally rock garden conditions because that is where you find it. Crevasses between rocks is where it lives. This is easily reenacted in your garden at the top of a porous rock wall. Blooms May-July for an extended time. The flowers go through a fascinating metamorphosis in color as they open, reach their peak of hot yellow and then turn to russet/red seed heads. These abandon the spike through autumn and spent flower spikes may be removed in winter. Water until you see the rosettes actively increasing. Then taper to once in a while. This species has a total of 13 (!) subspecies in Oregon alone. We have yet to delve into specific subspecies but if we did I would look for Eriogonum umbellatum var. modocensis and Eriogonum umbellatum var. umbellatum. Both are endemic to Mary’s Peak the tallest point in the Coast Range (4097′). So, I know that those (with immaculate drainage) can easily cope with higher rainfall. Rock garden staple and can also self sow in happy places. Very fun, sunny, satisfying native to grow. Associated plants in habitat are Prunella vulgaris var. lanceolata and Achillea millefolium, Sedum oreganum, Castilleja minuta and Penstemon cardwelii. Excellently adapted to gravel, crevice, gardens with an arid aesthetic. Amend the soil as for Agaves and it will thrive. Pronounced Air-e-OG-oh-num. Rosettes to 3″ tall, blooming stems to 1′ tall. Spreads, give it room. Oregon native plant.
Lupinus polyphyllus ssp. polyphyllus
Large leaf lupine. This is the form that is native to the western part of the state. There are 5 other subspecies, this is the Willamette Valley form. A large bushy perennial famous for the most showy flowers in the genus. This is the direct descendent that forms the colorful Russell lupines. A great large garden plant and not a long lived plant. Generally 3-5 years is antiquity for this species. The large palmate divided deep green leaves are coated in fine fur. This makes raindrops turn to pure mercury as they balance on the leaves. The most commonly seen flower color forms in the Willamette Valley are generally blue and purple and solid colors. The multi-color vastly larger selections are just as adaptable as the species. Large rocket like flower trusses rise to 3′ tall in late spring to early summer. Loved by insects the foliage is often fodder for native fauna. Excellent pollinator perennial or cut flower. Large peapods stick out horizontally from the spent flower stems. Reliably self sows if you contain the competition from foreign exotics and turf grasses. Potted plants should be watered regularly through their first summer. In subsequent years it can rely on natural rainfall. Very deer and rabbit resistant. To 3′ wide when happy. Protect from slugs/snails. Oregon native plant.
Piggy Back plant is what we called this moisture loving woodland plant. Its famous for its ability to sprout a new plant right from the leaf petiole, it forms roots and drops off the plant and roots into the ground. Its also commonly known as a very easy to grow houseplant. Native from Southern Alaska to Northern California. In moist, cool climates like the coast it can grow just about anywhere. The distinctly arrow shaped leaves cover the ground densely on a wide spreading perennial. In mid-spring 2′ spikes erupt with rows of brownish-red flowers. A member of the Saxafrage family and closely related to Heucheras and Tiarellas. this is as superb a garden plant. Evergreen and consistently moist shady sites are where it thrives. Though with some supplemental water it can make its home in some pretty challenging dry shade. Foliage forms spreading mounds to 10″ tall and spreads laterally 2′-3′ when happy. Plants shrink somewhat in winter, and not as verdant but they do cover the ground and out compete weeds. Great container plant. Very nice naturalized among ferns of any kind. Native to the Portland city limits. Oregon native plant.
Viola x cornuta ‘Xera’s Mix’
We’ve had a really good time selecting the most distinct flower colors of this mix of Violas. Brown, taupe, blue, gray, purple, are among the colors in this vigorous strain. These reseed with abandon and will occupy all kinds of niches in a garden. Containerized plants seem to cast seed when you are least aware. They generally germinate in winter and bloom in spring before setting seed and going to sleep for summer heat. Fragrance is another aspect in our selection. You can’t have Violas without fragrance. In autumn our winter mix has been chosen to handle the very worst cold and snow. Full sun to very light shade. Very easy and satisfying spring and autumn/winter extravaganza. They make sweetly scented, delightful bouquets. Xera Plants Introduction.
Heuchera sanguinea ‘Big Red’
This is a very old selected form of Coral Bells. The brilliant red flowers are much larger than the species. A very long blooming perennial beginning in April and contenting solidly to July. The soft green maple shaped leaves are handsome year round. Spreads to form expanding colonies. To 2′ tall in bloom above a congested rosette of leaves. Adored by hummingbirds and a very adaptable plant. Full sun to light shade in rich to average soil. Established colonies of this showy spring perennial can live for decades. Excellent massed tougher for a bold blast of color or spread out for explanation points of bright red. Light consistent summer water. Though established plants make due with much less. Mix with other similarly designed perennials. Very a good with Wulfenia schwarzii, Saxafrage x geum dentata, or even lower and airy growing Dianthus. Light deer resistance. Native to the southwestern United states mountainous areas.
Felicia aethiopica ‘Tight and Tidy’
Billions of blue daisies with a brilliant yellow center adorn profuse long stems. Bloom occurs unabated May-October. Remove spent flowers to encourage more. A more compact form of this shrubby tender perennial to 16″ x 36″ in a single season. Excellent performance in container plantings. This is a real work horse of a daisy whose airy sprays of daisies mix harmoniously with a number of schemes. In the ground this tender perennial can over winter in a mild year (above 20ºF). Excellent pollinator plant and a real hit in my garden with butterflies. Full sun to very light shade in rich to average soil. Light, consistent summer water. If it over winters cut it back hard after all threat of frost has past. Containerized plants can be moved to an unheated garage to over winter. Brilliant blue daisies are exciting. This plant will perform as a hardy perennial at the Oregon coast.
Streambank lupine or Riverbank lupine is widespread shrubby species native to western Oregon. Its full range is from extreme southwest British Columbia (where it is endangered) to northern California. Large growing, spreading plant that can almost achieve a sub shrubby habit. To 3′ tall in bloom forming an evergreen shrublet to 3′ across. From late April to early July spires of blue flowers with a white keel erupt from the plant. Very pretty in bloom and incredibly important to pollinators and insects who feast on the flowers as well as leaves. The true species has flowers that are all blue, its found primarily on sand bars in major rivers on the west side of the state. Most seed that is grown and dispersed is a selected bicolor flower. Short lived plant 3-5 years. Following the flowers conspicuous seed pods turn a dark color, These may be allowed to open and disperse in the OPEN DISTURBED SITES that it craves. Excellent in concert with California poppies where it has become a famous duo on our freeways in the spring. Good cut flower. Not bothered by deer. Water to estalblish then leave it to natural rainfall. Oregon native plant.
Carex praegracilis ‘Chisai’
Excellent dwarf form of our native meadow sedge. To just 6″ tall it forms dense spreading evergreen patches. In spring to summer both male and female flower spikes rise to just a few inches above the foliage. Nice looking compact plant that retains its verdancy through the winter. An admirable substitute for lawn and mowing is not necessary. This species is most widespread east of the Cascades. Its native throughout the west and this form was identified in California. Plant on 10″ centers for a modern massed ground cover. The mid green to ochre green leaves are dense and smother competition. This creates less of a hummock affect and more of a small dome. Very easy to grow. Excels in containers. Full sun to light shade, also very high overhead shade (a tall tree canopy). Amending the soil with compost and fertilizer will increase vigor and green appearance and quicken establishment. Spreads by slowly expanding rhizomes. Excellent between stones or pavers. Tolerates light foot traffic. Not really large enough to be bothered by deer once established. Hardy below 0ºF. This useful plant has great smaller scale, ease of culture, and consistent good looks. This would be an excellent smaller grassy component of a meadow. Established plants can take quite a bit of summer drought. Carex praegracilis is an Oregon native plant.
Cistus libanoticum ssp. major
Unique in that the leaves are thin and willow-like they still harbor plenty of waxy perfume. A somewhat gnarled looking shrub over time with plenty of character. In May-July 6″ long stems erupt from the top of the shrub, elongate and produce clusters of large pure white flowers. Blooms for an extended period but each open flower lasts only one day but is replaced by a steady supply. Full sun and average to enriched soil. Water to establish then less to none in subsequent years. In time it develops a shredding, twisted, gray trunk. Moderate deer resistance. Aromatic on warm days. Mixes very well with Arctostaphylos as well as Ceanothus. A really great rock rose. Tp 3′ x 3′ in 5 years.
Ceanothus x ‘Xera Azul’
Very fortuitous, we planted 5 species/cvs of Ceanothus in our stock beds and they of course got a little frisky. We ended up with one stellar seedling that has impressed us so much that we showed it to Ceanothus Guru Dave Fross of Native Sons Nursery and he was impressed. In its 3rd year its produced copious blooms that are about the darkest blue that I’ve seen. Only the cultivar ‘Kurt Zadnick’ has deeper tones but this plant displays them differently. Large fluffily black/blue trusses of flowers on a lower and spreading plant. To 4′ tall by 6′ wide very fast. Glossy undulate leaves look nothing like their prospective parents. It has shown great cold hardiness as well as drought adaptation. Um…..we’ve never done anything to it. It hasn’t ever even had supplemental irrigation. So, extraordinarily climate adapted. Also, most Ceanothus seedlings require 3-4 years to commence bloom. This precocious little seedling bloomed its second year. All of this adds up to a great new cultivar. Full sun to very light shade and average soil. Water for the first season to establish then none in subsequent years. Blooms late March to late April and occasionally on new wood through summer. This would make a great bank cover with Cistus and Helianthemum, Eriogonums. So cool we named it Azul. The beginning of a GREAT Ceanothus.
Xera Plants Introduction
Yucca (nana) hermmaniae
Adorable and rugged little dwarf Yucca from southern Utah. Tight round quills are decorated with filaments on the leaf edges. Not a friendly guy and very slow growing. Forming spheres of spikes to 1′ across and multiplying to produce colonies with pups. Full sun and very well drained soil of average to poor fertility. Requires excellent air circulation- no crowding. Plants that are smooshed with little air circulation protest heavily and it then takes a while for recovery. Open and free in rock garden conditions produces the happiest plants. At home nestled with boulders or as a finer texture element with Agaves. In time it produces adorable and conical shaped hoods of flowers- a gnome wedding. Excellent in containers- open, well drained containers. Light summer water during hot weather seems to speed growth. Locate away from paths. Owwie. Strongly deer and rabbit resistant.
Arctostaphylos x coloradensis ‘Panchito’
Several wonderful attributes makes this a great Manzanita for widespread use. Its extremely cold hardy, a naturally occurring hybrid from southern Colorado- it can handle temperatures lower than -20ºF. Its a great size- slow growing to just 3′ x 3′ in 8+ years. The matte green foliage is dense (almost boxwood-esque) and is a great foil for the clusters of pink buds that relax to lighter pink when open. Full sun and average, unimproved soil. Water to establish then only what falls from the sky. This dainty almost formal looking shrub finds a happy home in smaller gardens, rock gardens, and thrives in Central Oregon. In time the trunks exfoliate to glossy maroon- it take quite a few years for this to be an outstanding feature. Mounded and dense for the first part of its life- expect just several inches of growth per year.. Open exposure with good air circulation. Great performance in Gorge outflow. A perfect substitute for ‘Greensphere’ that is both hardier to cold and a little easier to cultivate. Russet red berries that follow are a treat for the birds that get there first. Accepts the hottest aspects, drought, and brutal cold. Bienvenidos, Panchito!
Sisyrinchium x ‘Stripey’
PRECIOUS and showy blue eyed grass. Sometimes variegation really works on a plant and this is one of those cases. Grassy leaves are soft green with prominent ivory stripes. This backdrop virtually glows in combination with the relatively large purple/blue flowers. Blooms April-July and appreciates rich soil with regular water to really get going and colonize. Excellent rain garden subject. Its best position is possibly in containers. Upright leaves have a pointed top to 6″ tall in bloom. Excellent contrast between the variegation and the flower color. Full sun. Moderate deer resistance. Showy, sweet perennial. Mix with other low perennials. Combine with Acaena inermis ‘Purpurea’ and Dianthus ‘Pink Pyrenees’. Fun to grow. Flowers close tightly at night.
Prairie June Grass is a widespread cool season grass that was common in the Willamette Valley. A tight clumping grass with soft blue/green foliage that rises to about 18″ tall forming a clump as wide. In June-August feathery gray/tan plume of flowers erupt and soar above the grassy clump. In bloom it is about 30″ tall. A long lived grass for virtually any soil in full sun. Rich soil results in a very large plant. Average soil that has been double dug to add oxygen is usually all thats necessary. Water the first season to establish then none in subsequent years. Mix with other native perennials and annuals. A great companion for Sidalceas as well as Solidago and Douglas aster. Will often self sow. Keep it away from highly manicured areas. Otherwise the clump keeps to itself. Very easy to grow perennial grass that is found throughout the northern hemisphere. An authentic grass for a Willamette Valley prairie. Winter appearance is green and verdant. Summer brings tan drought dormancy. Oregon native plant.
Charming beyond words this Chilean sub-shrub has been given an informal common name of cup flower. Petite, almost succulent foliage is deeply and irregularly serrated along semi-woody stems to 30″ tall and 3′ wide. In July-October on new wood clusters of downward and outward pointing up shaped soft lilac flowers have an interior of conspicuous spots. Gloriously fun plant for a protected location. Mulch for the first winter or two. Once established it has similar hardiness as hardy Fuchsias. Full sun and rich soil that drains. Regular summer water encourages a fast recovery from the base if frozen. Cut back hard in early spring when all danger of frost has past. Flowering commences with the heat of summer. Protect from blazing afternoon sun. Works well on an eastern aspect. Loved by pollinators and even hummingbirds. Long blooming charming sub-shrub. Not bad in containers, protect containerized plants from temperatures below 15ºF. Wonderful Chilean native. Not a bad cutflower. Related to Calceolaria (Pocket Book Flower). Protected location such as a south or east facing wall is beneficial.The flowers virtually glow.
Princess flower is a tender shrub that becomes a rapturous cloud of velvet purple flowers for all of summer. Three inch wide flowers have the wonderful backdrop of velveteen clad deep green leaves. To 4′ x 4′ in a seasonal container. Full sun to very light shade and rich soil with regular water. Appreciates a handful of all organic fertilizer halfway through the season. Over winter containerized plants in an unheated garage. Cut back hard, fertilize and place outside when all danger of a freeze has passed. In very protected gardens near the beach this shrub may be grown in the ground. To 8′ tall x 4′ wide. Freezes back below 27ºF and is root hardy to the low 20ºs. Mulch in autumn. Princess flower hails from the mountains of Brazil.
Grevillea juniperina ‘Orange Zest’
We grew and selected this spiky long blooming juniper Grevillea years ago, After a few years hiatus we’ve brought it back. Upright then spreading evergreen shrub. Incredibly sharp needles pose as the leaves. Curly orange typical spider flowers for the species with profuse flowers. Bloom is year round on established plants but for the first several years it peaks in spring. To 3′ x 5′ in 6 years. Full sun to part shade- Increased bloom and a more compact habit will be achieved in full sun. Tolerates a wide variety of soils but seems to excel with at least moderate drainage. Adaptable to clay soils. This is one of the cold hardiest cultivars of this species enduring 5ºF with no damage. Best in an open exposure with reasonable air circulation. No crowding with other plants. Excellent in the back of a rock garden or in a shrub border with Manzanita and Halimium. Water to establish , once its growing in earnest you can taper off and drought adaptation is exceptional. Avoid enriched soils, best in average unamended soil. Double dig a wide hole to assist the plant in rooting into virgin soil. Extremely deer resistant but adored by hummingbirds and many other birds in general. Very fun shrub to grow.
Xera Plants Introduction
Osmanthus armatus ‘Zipline’
Sometimes the garden goddess smiles on us. I found this sport (a variegated stem) on my Osmanthus armatus ‘Jim Porter’ and I separated and rooted it. It has become a fantastic extremely showy shrub. This is welcome because Osmanthus armatus is not a particularly conspicuous species. It has serrated deep green leaves and small white flowers in autumn that emit a faint but sweet fragrance. Variegation improves the species markedly. The variegation is very stable, I have yet to see any reversions. Each leaf is symmetrically serrated and the variegation is vivid and adds an incredible amount of depth. Large growing shrub to 9′ x6′ in 10 years. Excellent cold hardiness on a brilliant evergreen. Full sun gives the best variegation and I have yet to see it burn in the hottest conditions. Excellent specimen, hedge, or screen. Cut foliage lasts for about 1 week in a vase. Light consistent summer water to establish then very tolerant of dry summer conditions Cold hardy slightly below 0ºF and durable and long lived. In time it can make small tree status which makes a very striking tree. A wonderful shrub and a happy discovery, See video below.
Xera Plants Introduction
Fool’s Onion, though this close relative of Brodiaea is easy to tell apart from Allium as the leaves and stem have no onion odor. A sunny native perennial bulb that forms colonies of white in May-July in meadows, glens, and swales. To 15″ tall in bloom but usually shorter the leaves emerge in mid winter and persist until summer drought. About that time the flowers erupt into clusters of white flowers. Great native bulb for naturalizing, Water if planting from a pot, otherwise it requires only what falls from the sky with a distinct dry period in summer. Associated plants are Ranunculus occidentalis- Western Buttercup, and Brodiaea elegans- Cluster lily, and Plectritis congesta- Sea Blush. Native in clay soils that dry completely in summer. Goes very neatly dormant in summer- nothing is left. Excellent in rock garden conditions. Full sun to very light shade. Moderate deer resistance. Native though out western Oregon. Sweet cutflower Very good for butterflies as well. This plant once occupied large areas of the Willamette Valley, that territory has shrunk considerably. Oregon native plant.
Wonderful native bulb that has several common names. Harvest lily is one as well as cluster lily. This gorgeous inhabitant of dry hillsides from British Columbia to southern California erupts in clusters of blue flowers just as summer drought ensues. To 14″ tall but normally shorter a clump of scrappy green leaves comes out in autumn and persists until bloom time. As the leaves go dormant the bulb sends up its bloom. Easy to grow if you accept its requirements. Bulbs that are potted should be watered after planting but established plants should rely only on what falls from the sky. Best to not irrigate in summer. In time it spreads by both increasing bulblets as well as seed. Excellent planted among Festuca roemeri var. roemeri as well as Festuca californica where it occurs naturally. Excellent pollinator bulb in the lily family. Leaves are deer resistant but flowers are not reliably deer proof. Full hot, all day sun in soils that dry completely in summer. Native throughout the Willamette Valley and into the gorge locally. Oregon native plant.
Erica cinerea ‘Velvet Night’
Heathers and Heaths are fun to grow, but the tales of failure are epic. The easiest Heaths are Ericas and they all like some sort of regular summer water to thrive, bloom and adapt. This is a favorite shrub aside from being the darkest flowered Heath that we’ve seen. Beginning in June with a summer crescendo that bleeds into autumn with deep beetroot purple flowers on deep black green needle like foliage. To 2′ x 2′ in 3 years and fairly upright for an Erica cinerea. Outstanding long season of summer bloom that is a thrill to hummingbirds as well. Great aesthetic and cultural companion for Grevilleas. This Heath will bloom while most Grevilleas are having a summer bloom rest. Shear after blooming (fall) this will increase density as well as blooming wood. Full sun and rich to regular soil with regular irrigation for the first 3 years- then much less. This is a dark shadow of a shrub. We love it. Moderate deer resistance. Mulch heavily with bark after planting and annually. The secret to Heaths and Heathers in our climate is mulch, mulch, mulch. Excellent performance at the coast.
Tongue fern from Asia is also known as a leather fern in reference to the robust thickness and texture of the leaves. These evergreen ferns creep stoloniferously to create patches. Not rocket fast, but you can enhance growth in rich, well drained soil with regular SUMMER water. This semi-subtropical-ish fern grows fastest during summer so thats when you supply water. Otherwise it is tolerant of very dry conditions and will make due with one spring moisture burst of growth. Very good appearance year round. Part shade to shade- reasonable shade, not a dark planter under the Brady Bunch stairway but bright shade. Mixes well with Aspidistra elatior (Cast Iron Plant) and Asarum splendens a green and textural combination that looks good year round. And sometimes in dry shade thats the best you can ask. HEH. To 18″ tall and spreading several feet wide with care. Long lived and cold hardy to about 5ºF. Avoid strong subfreezing east wind which can scorch the edges. Great in shady containers. Even successful as a houseplant. Moderate deer resistance.
Arctostaphylos densiflora ‘Type Form’
This is the species that is an important parent in some of the most popular hybrid Manzanitas. From a very restricted range in Sonoma County CA this lovely Manzanita sports gray green sharp tipped foliage and wonderful glossy mahogany bark. Moderately fast growing evergreen shrub to 7′ x 7′. In winter white tinted pink urn shaped flowers occur in conspicuous clusters. Very pretty. Orange tinted glossy berries follow but are quickly consumed by wildlife. Easy shrub for full sun to very light shade and everage, un-amended native soil. Avoid anywhere that there is standing water in winter. Excellent on slopes and somewhat formal in appearance as opposed to many species. Very rare in commerce. Excellent shrub that is beautiful year round. No summer water when established. This species is critically endangered in Sonoma County, CA. In fact it is possible due to extensive fires recently that this plant is functionally extinct in the wild. Handsome shrub.
Camellia sasanqua ‘Otome Sazanka’
This is one of my favorite fall blooming sasanquas. Beginning in November and continuing to about the first of the year it produces copious double flowers of a soft, antique pink. The shading of the petals give the impression of an aged flower. VERY pretty. Very dark green foliage is glossy on an upright and then distinctively arching shrub to 3′ x 5′ in 6 years. Give this elegant shrub room to spread, it will grow faster than you think. Full sun to part shade in rich soil with regular summer irrigation. Established plants can survive on just several drinks per summer. This sasanqua does not have the sweet earthy fragrance that many do. The soft pink 3″ wide flowers are born in profusion. Very easily trained as an espalier. Open flowers are cold hardy to about 27ºF. Incipient flower buds are much hardier. Good looking shrub year round. Very elegant late blooming sasanqua that is welcome late in autumn. A very old Japanese selection where this species is native.
Heuchera sanguinea ‘Hot Mess’
We found this vigorous seedling in a batch of Heuchera sanguinea. The leaves are pale green and liberally splashed with white. Unlike, the red flower of the species straight spikes of HOT PINK flowers rise in a cloud above the playful foliage. This is just a seedling and unlike many variegated plants it shows excellent vigor and longevity. Evergreen clumps of foliage. Loved by hummingbirds in bloom from April to mid-July. Tolerates full sun to quite a bit of shade at the expense of blooming Excellent paired with ferns Hosta, Tiarella. To 14″ tall in bloom and spreading to about 2′ wide when happy. Rich, moisture retentive soil high in organic matter. Established plants are surprisingly drought adapted. Do not let other plants crowd or over top this perennial. The lack of light and competition will take it out. Instead match it with a similar sized perennial. See above. Easy, forgiving perennial.
Xera Plants Introduction
Camellia sasanqua ‘Double Rainbow’
This is an extraordinary fall blooming sasanqua Camellia with very showy flowers and a nice upright habit. Large double cupped flowers emerge from a pink bud and unfurls to a pink edge with a white center. As the bloom ages it turns mostly to white with pink tinted flowers. Bloom appears from late September to late November. Glossy, very dark green leaves are formal in appearance and a great backdrop to the profuse 4″ wide flowers. Full sun to light shade in rich to average soil with regular summer water. This improves fall bloom. Otherwise very established shrubs can get through summer with just a few drinks. As with most sasanquas the flowers have an earthy, light, sweet scent. Long lived, hardy, easy to grow evergreen with a great season of bloom. Prune if needed AFTER flowering has ended. Wonderful as a stiff upright espalier which will protect the flowers from the vagaries of weather. Stunning in bloom. Tolerates hot aspects.. To 7′ x 6′ in 8 years.
Callistemon pityoides ‘Harry’
This is a great dwarf form of Alpine bottlebrush and its most useful for its size and shape than for expansive floral displays. However, when in bloom its beyond adorable. Slow growing rounded shrub to 1.5′ x 1.5′ after 7 years. The small needle-like leaves are medium green with a distinct ochre cast. Very tough evergreen for the most challenging sites. Accepts intense reflected heat, summer drought and arctic cold. This is a true alpine plant. No pruning necessary as it naturally assumes a dense rounded habit with no intervention. Good deer resistance. Excellent as in informal unpruned hedge. Accepts almost all soil types from saturated clay to sand. The diminutive flowers are actually small circular balls of light yellow stamens- adorable. Blooms May- June and possibly again in autumn. Native to the very highest elevations of Australia. Flowers are attractive to hummingbirds and butterflies. Combines well with wild flowers or perennials. Nice looking shrub all the time. This is an introduction from Desert Northwest Nursery. And its an excellent plant. Full sun- not tolerant of shade.
Bolax (Azorella) gummifera
Incredibly useful and handsome and tough creeping evergreen ground cover. The fine interlaced leaves have a texture very much like plastic or tupperware. It creeps along forming tight rosettes that join. In summer the whole surface of this flush plant is covered in chartreuse yellow flowers. Not showy but conspicuous for a plant that looks uniform and green all year. One of the best ground covers between pavers as it can handle compacted soil better than other small scale ground covers. And this is a small scale ground cover, don’t try to cover acreage. Be reasonable and expect good coverage over a space no larger than 5′ x 5′. Glossy foliage sparkles when wet. Regular summer water speeds growth though it is tolerant of dry periods but not complete drought. Expect each 4″ plant to expand to the size of an apple pie in a season. Completely deer resistant. Top dress with compost every few years- especially if it is between pavers. To 1/4″ tall by 1′ wide. Full sun to the very lightest shade. Carrot family.
Coral Bells. This is the original species that lept into gardens nearly a century ago. Native to the mid and higher elevations of the southwestern U,S. this is a tough, beautiful, long blooming species that will live for decades in a garden. Maple shaped leaves, occasionally decorated with white form rosettes and in time colonies. In April to July a fantastic display of red flowers on 16″ straight stems. They create a pool of color above the plants. We love this species also for its ease of cultivation. Full sun to part shade in rich to average soil with light summer water, or none when a patch is established. Excellent long lasting haze of red color for the front of a border or with in other perennials. Adored by hummingbirds and moderately deer resistant. Very easy to transplant and move around where you need some color. Evergreen to semi evergreen foliage. Rosettes to 1.5′ wide. Indispensable, old fashioned but always beautiful and reliable. Avoid heavily compacted soils.
Myrtus communis ‘Emerald Compact’
This is a seedling myrtle that showed up in our nursery. I moved it to a stock bed and observed it for several years. Its proven to be hardy to lower than 15ºF and its a dense and compact growing form. Good looking evergreen that has deep forest green foliage with a slight gloss. Dense growth forms a shrub to 3′ x 3′ in 6 years- progressively larger after that. In late summer to early autumn a procession of pure white flowers with a central boss of exerted stamens. This aromatic shrub is adapted to hot dry conditions and light to little water once established. In fact, the more lean the conditions the hardier this myrtle will be to cold. Black elongated drupes follow the flowers. Formal appearance that can be even more formal with pruning. Though, its naturally dense habit makes pruning less likely. Great against baking hot south facing walls. Loves the zone of south facing planters that are asphalt on one side and a hot wall on the other. Best as a specimen- not a hedge as it can be prone to damage in severe winters ( below 10ºF) which recovers quickly in spring but makes it less useful as a hedge. Great container subject. Moderate deer resistance. Tolerates VERY dry summer conditions. Full sun to quite a bit of shade at the expense of a dense habit. Very durable urban shrub. Protected location. Locate out of the path of subfreezing east wind.
Xera Plants Intoduction
Erodium x ‘Merstham’s Pink’
Flowery, easy rewarding perennial that blooms consistently from April to September. This sprawling plant assumes a rounded shape and bears 4″ stems with cup shaped rose pink flowers. Loved by pollinators and if it takes a break from blooming in the heat you can give it a hair cut and and some water and wham! you are back in business. The low, flush leaves are bright green and frilly and mostly evergreen. Great wildflower appeal that does not flail or swamp as most hardy geraniums do. It sticks to its place- about 1′ x 1′. Very good along steep walls or in a cottage garden. Excellent companions are Dianthus ‘Dainty Dame’, Scutellaria suffrutescens, and Penstemon ‘Enor’ for a low water flowery ensemble. Cut back hard in early spring. Light consistent water improves blooming. Great nectar source for Butterflies and bumble bees often nap in the cup shaped flowers. Cold hardy. Some deer resistance. Adaptable. Full sun to very light shade or high overhead shade. Great in containers. Long lived perennial cranesbill.
Iris x pacifica ‘Joey’
Kind of an obscure Pacific Coast Iris that Greg claims is a little more orange with brown striations than this picture depicts. Grassy leaves are evergreen and in May/June a continual parade of multi-colored flowers on 14″ cantilevered stems. Very easy to grow west coast native Iris hybrid that increases its bloom as the clump increases. The orange/ and maroon/cranberry flowers are visible from a distance and are particularly fetching when back lit. Completely deer and rabbit resistant perennial for part shade to full sun. Rich to average soil. Water diligently for the first summer, in subsequent years leave it strictly alone. Wonderful between and near Manzanitas, other west coast drought adapted shrubs.
Arctostaphylos x ‘Gunmetal’
This is a mysterious Manzanita and one of the finest. We’ve driven by it for years on the highway to N. California and for years it captured our attention. A smaller rounded shrub of metallic silver gray with white flowers. So far it does not key out to any specific species so we’re pretty sure its a naturally occurring hybrid. And the silver gray foliage could be a result of a little bit of A. canescens. But the area where it lives has about 8 species and god knows how many hybrids in close vicinity. Either way its a stellar garden Manzanita with pointed metallic silver foliage and clusters of showy white flowers in winter/spring. The bark is a wonderful contrasting smooth deep mahogany- a great foil to the foliage. To 4′ x 4′ in 8 years. Moderately slow growing for an Arctostaphylos. In habitat it perches on a nearly vertical cliff of basalt. So, its adaptable. Not prone to black spot and it hails from an area with a naturally high rainfall. Avoid all supplemental water when established. It literally thrives on neglect. Silver foliage shines year round. Limited quantities. A Xera Plants favorite. Oregon native plant.
Xera Plants Introduction
Arctostaphylos auriculata ‘Knobcone Point’
Interesting and very handsome compact Manzanita that retains what appears to be juvenile foliage. Each rounded leaf has small indentations that give the plant a finer mein. Silver/ gray foliage is handsome all the time and the leaves clasp the stems in a symmetrical way. In January to April clusters of pinkish/ white urn shaped flowers appear at the branch tips. Not the heaviest blooming Manzanita. The mature trunks and stems revert to a solid mahogany glossy finish with time. Dense growing to 4′ x 4′ in 6 years- larger in time. Beautiful, architectural shrub for full sun and dry summer conditions. No supplemental water when established. Rounded good looking plant for hillsides, parking strips, dry shrub borders. This species is native to mid to higher elevations of the Bay area and has performed wonderfully in our gardens. A naturally dense growing plant.
Hyacinthoides (Scilla) lingulata
We adore this little fall blooming bulb. In September to November it bears clusters of small off blue flowers. They emit a powerful fragrance that is detectable many feet away. Small to only 4″ tall but multiple spikes add substance. The rounded longer leaves emerge simultaneously with the flowers and persist over winter. Best in a summer dry environment. Which means that once established its best with just the rain that falls from the sky. Hellstrips, rock gardens, the front of borders. Average to enriched soil in full sun. These multiply surprisingly fast and in time you get expanding colonies. Dormant in the heat of summer. Delightful fall blooming bulb we wouldn’t be with out. Moderate deer resistance and not bothered by rabbits. Photo by Andy Stockton.
Arctostaphylos x ‘Rosy Dawn’
This is a little gal. She creeps slowly along the ground forming a dense dome. Round glossy leaves add to the the overall dome shape. In winter into spring a continual procession of soft pink flowers. They come in groups and are more intensely pink with cooler/cold temperatures. To about 1′ tall by 3′ wide not very quickly. Dense and smothers weeds effectively. Grows about 3″ per year, faster in more fertile soil. Great in year round containers where its restrained growth and ability to adhere to contours makes it perfect for life on the edge. Not quite as vigorous as kinnnick kinnick and actually a better specimen than ground cover. Great in rock gardens. Little summer water when established. Nice resistance to black spot. Appreciates a warm location. Moderately deer resistant. We have yet to see it produce berries. Or they were snagged by birds before we could notice. Demure little shrub. Looks glossy and fresh year round.
Pelargonium ‘Garden Bouquet’
I’d swear this is just a species pelargonium and probably there is at least some pure species in the parentage. Its a remarkable tender plant that blooms its brains out for months non-stop. These pale pink and dark purple studded flowers decorate a hazy, wiry frame of very slight foliage. Its pretty and it gives the constant bloom a very wild flower mein. Forming a rounded shrub to 20″ x 20″ in a season. It grows fairly rapidly in rich soil enriched with all purpose granular organic fertilizer. Excellent in mixed containers and unflinching in the most blazing conditions. Full sun. Also, cheerful by itself in a large terra cotta pot. The blooms begin in May for months it is never without flowers. Regular water. Mixes well with tender (and hardy) succulents. One of my favorite containers is this plant in the center surrounded by trailing Sedum palmeri. Hardy to about 27ºF- and worth overwintering as a houseplant in a very bright window. Give it good air circulation. Excellent performance at the Oregon Coast.
Pelargonium x ‘Alpha’
There is something so classic and special about this zonal Geranium. Chartreuse leaves are banded with a darker zone on each leaf. This forms a repeating pattern that is very vivid. Long stems with clusters of neon coral/pink flowers appear continuously from May to frost. This zonal geranium does not just grow up. It spreads laterally in time and a single plant in a container will trail gracefully over the edges. Full sun to very light shade in rich, well drained soil with regular irrigation. This zonal really likes hot conditions and good air circulation. Classic occupying a row of terra cotta pots. Vivid in containers and a very good mixer. Very easy, bright, and satisfying tender perennial.
Arctostaphylos hookeri ‘James Roof’
Smaller growing Manzanita that assumes the twisted form of a bonsai with age. In fact this 2′ x 4′ wide decumbent shrub makes a wonderful, long lived container plant. In the ground it excels on slopes and other places where standing water never occurs. Full sun to high overhead shade (a high tree canopy). In late winter scattered smaller white urn shaped flowers decorate the branch tips. They morph into highly prized fruit for wildlife. Sage green diamond shaped foliage it lightly twisted and terminates to a sharp tip. Twigs, branches, and trunks all have a glossy mahogany finish. Great shrub for covering low slopes. Effectively blocks weeds. Water to establish and then set it free. Several plants may be massed to produce a small scale, drought adapted ground cover. Exceptionally garden tolerant selection that is exceptionally handsome. This species is native to the central CA coast and has been one of the best for garden culture in our region. Accepts light irrigation in summer. Excellent performance at the Oregon coast. It thrives on sandy soils. Nice smaller growing selection. Naturally summer drought adapted. Orange drupes are showy.
Passaflora caerulea ‘Snow Queen’
Ravishing pure white intricate flowers flow from this passion vine, which can be rambunctious in the wrong place. Large growing plant to 20′ (long) tall and attaching itself firmly by tendrils. Full sun in average soil with a lot of water to establish. Once established it is on its own. Too much irrigation and soil that is too rich leads to prodigious growth that can get rank and lack bloom. So, don’t starve it, just put it in reasonably good soil, that you have double dug. Water faithfully to spur growth. Semi-deciduous to evergreen in our climate.In winters below 15ºF and depending on the length of cold it can be totally deciduous. Good performance on the Oregon coast. 5″ wide flowers have a light sweet fragrance. Moderate deer resistance- it can also climb out of reach. Wonderful white passion vine.
Daphne odora ‘Zuiko Nishiki’
Excellent all green form of Winter Daphne with dark pink buds that open to softer pink insanely fragrant flowers from January to April. One of the larger growing cultivars 4′ x 4′ in 6 years. Excellent in part shade to shade, including dry shade, where it will continue its fabulous bloom. ‘Zuiko Nishiki’ is known for superior cold hardiness as well, taking temperatures to 0ºF with little harm. This is a great cultivar for colder gardens. Moderate rate of growth about 10″ per year. Supremely deer resistant evergreen shrub that will never be bothered. Prune if needed very lightly after blooming has ended. Regular water to establish then very drought tolerant. Loves clay soils that dry in summer. Irrigate only when very dry. This increases the flower bud set for the following year. The sweet lemon fragrance fills the air for months. Somewhat formal appearance out of bloom.
Magnolia compressa var. langyuense
This tree is wonderful in many ways. Its staunchly evergreen, but rather than the somber glossy leaves of Magnolia grandiflora these simple leaves are grass green and matte. Moderately fast growing shrub/tree, on average 1′ to 2′ per year if sited correctly In mid April to mid May the most exquisite miniature magnolia flowers erupt directly from the stems. These adorable ivory pinwheels have a sweet sophisticated fragrance. Well behaved plant that is moderately dense and always healthy looking. Best in a protected courtyard or agains a west facing wall, do not expose it directly to arctic east winds. To 14′ tall by 6′ wide in 10 years. Full sun but not reflected heat and adaptable to the dappled light of woodlands. In our experience it was unharmed at a brief dip to 7ºF.. This would make a fantastic and adorable espalier subject. The way the perfect flowers are arranged on the stem would lend itself well to that method. Rich to average soil, including heavy clay soils, Best with intermittent deep irrigation in summer. A deep soak once every two weeks on established plants. This rare smaller evergreen Magnolia deserves wider use in our climate.
Toothed leaved Azara is a somewhat obscure evergreen tree native to South America. Closely related to the more common Azara microphylla, this species has much larger leaves and MUCH larger gold flowers. The puff ball gold flowers deck all the boughs in an opulent spring display that lasts for weeks. An upright broad spreading evergreen whose crown usually assumes a conical outline. Spreading branches hold the foliage which is very substantial. To 18′ tall and half as wide in 10 years. Best in a protected location, out of east wind, on the edge of a woodland or near a house. The large flowers truly are a spectacle and emit a light sweet fragrance. Full sun to high overstory shade in rich soil with occasional deep soaks in summer. Grows 1′-3′ per year and faster with attention to water. More tender as a youngster gaining full cold hardiness with age. Established trees endure 5ºF by losing many leaves- they can also disappear in particularly enthusiastic bloom seasons but it regains foliage very fast by early spring. Excellent performance at the Oregon Coast. Very elegant tree. Chile/Argentina.
Stock, the common early spring cut flower with that is wonderfully fragrant of cloves. The sweet perfume can be detected at quite a distance. This is a cold hardy, PERENNIAL version of that beloved flower. Forming a semi-woody dome like shrub multiple spikes to 10″ long eminate from the crown and bear pristine cleanly white flowers with that dazzling perfume. Great fragrant filler in bouquets. Native to mountainous areas around the mediterranean. To 2′ x 2′ and becoming a multi branched shrublet. Full sun and rich to average soil with light consistent summer water for the first season. Good drainage is important and its a natural plant for a slope. Established plants can get through summer without irrigation. The long strappy leaves are gray/green and add to the overall appeal especially when decked with white flowers. Average life span 5-7 years. Do not coddle. Combines well with Cistus, Halimiums, Helianthemums. Dianthus where it will compete for perfume. Very reminiscent of a Wallflower (Cheiranthus) and accepts the same cultural requirements. Blooms May-August. Pronounced muh-TOY-luh
Ceanothus impressus ‘Vandenburg’
Most Ceanothus are famous for their intense blue and profuse flowers, this interesting shrub has the typical masses of sky blue flowers which obscures the tiny warty foliage. To 5′ x 8′ and spreading wider than tall it becomes a cloud of blue in April and pollinators take notice. Rolling in bees and every other awake pollinator a shrub in full bloom is a buzzing fountain of activity. Fast growing, wiry, dense shrub with extraordinarily dark green tiny leaves. This gives the shrub the distinct appearance of a cloud. Full sun and average to poor soil including heavy clay soils that dry in summer. No summer water once established. Remarkably drought adapted west coast native shrub. Very easy to grow large, showy, shrub for wild areas, blasting hot urban hell scapes. Not totally deer resistant but better than most other species. Excellent performance at the Oregon coast. Endures sandy substrates and even a bit of salt wind. Attracts some of the first butterflies to emerge. Cold hardy to slightly below 10ºF for brief periods. Recovers from cold damage completely by bloom time.
Camellia japonica ‘Yamoto Nishiki’
Extraordinary Higo Camellia that is wildly showy and fun to grow. Higo Camellias are a form where the stamens rather than being clustered together in the center are instead splayed out in the shape of a star against smaller flat petals. They are surprisingly rare in the United States. Its a different look for a japonica and we love it. Moderately fast growing handsome glossy evergreen shrub for full sun to shade. To 8′ x 5′ in 7 years. Regular summer water speeds growth and increases flower bud set. Mid-season bloomer with flowers opening from February on. Rich to average soil, definitely apply ample mulch when planting. Good looking shrub at all times- w/ a somewhat formal appearance until the blooms open. 4″ wide flowers have flat petals that are white striped and stippled in peppermint red. Takes low water conditions when established. Long lived.
Camellia x cuspidata ‘Magi’s Mystery’
Our friend garden designer plantswoman extraordinaire Magi Treece spotted this Camellia and observed it over time. I too had noticed it around town- always large and VERY old. Its most conspicuous trait is to produce simple single fluted ivory flowers from pink buds. Up close these 3″ wide flowers have a decadent sweet scent. Its appearance is most like the species Camellia cuspidata which is a very cold hardy species known for its fragrant white flowers. Blooms appear from December (Often as early as November) and open until the end of February. The elegant flowers are tough and it takes some serious weather to impede or even damage the flowers. Deep green leaves are long and thin and very glossy/handsome with a sharp tip. The entire plant is good looking at all times. Ancient varieties around town are upwards of 15′ tall and 3/4 as wide. I’d say it would be an 8′ x 8′ shrub in 10 years. Regular water speeds growth and assists in bud set for the following season, this is only important in summer. Excellent specimen or hedge. This is one tough and beautiful Camellia. Dig a large hole to disturb the soil around the planting site and set the plant in the hole even with the soil horizon. Backfill, water and mulch. Magi queried Camellia Forest about this plant with no luck. I queried Nuccio’s and their best guess was that it was a form of C. cuspidata or a hybrid close with it. Either way its one of our most favorite Camellias and we have our sweet friend Magi to thank. This Camellia looks and acts very much like an evergreen Magnolia and it could be used as a smaller substitute. The flower fragrance on warm days is a bit like a Gardenia. Moderately fast growing.
Xera Plants Introduction
Sarcococca ruscifolia var. chinensis ‘Dragon’s Gate’
Graceful and formal at the same time. This low arching form of winter box is wonderful with uniform thin, deep green pointed foliage on arching stems. In mid-winter to early spring the undersides of the stems are clad in fine powerfully FRAGRANT white flowers at every leaf axil. The fragrance spreads for quite a distance on mild winter days. Following the flowers are berries that turn black and arrive at red. Handsome low shrub to 2′ tall and 3′ wide suckering to form patches with time. Moderately fast growing and easy to establish shrub in the BUXACEAE which means that this boxwood relative is also deer resistant. Excellent performance in part shade to shade but not low dense shade. Massed it performs as a large scale ground cover. Light consistent summer H20 for the best looks. Takes dry conditions in shade once established- especially if you apply mulch liberally. Unlike the species it does not lose leaves in bloom which is an important difference. Finds a home under dark stairwells and foundation plantings. Impressive relatively new selection. China.
Springbank Clover. Fascinating perennial clover that was once widespread in wet areas of the Willamette Valley and is now found in restricted sites there but is much more prevalent on the coast and east of the Cascades. A pretty spreading spring wildflower with heads of brilliant magenta/purple flowers. Mainly in spring but also in summer if wet. To 4″ tall it can be up to 2′ wide in favorable conditions. Though mostly restricted to seeps and wet areas now it once made life under native white oaks and there indigenous people would use it as a food source. The creeping green stems root where they touch the ground. Stems were harvested and steamed as a vegetable and they replanted as they harvested the remaining stems ensuring another crop. Not a long lived perennial 3-5 years but it sets copious seed. Wet sites in moisture retentive soil. Mainly riparian in habitat. It can dry considerably in summer and still thrive. But regular water is what it wants. Fun plant to grow that has lost a LOT of its native range. In habitat it is best seen on the wet cliffs adjacent to the beach. Great pollinator plant. Easily overwhelmed by invasive exotics. Oregon native plant.
Arctostaphylos pumila ‘Grey Leaf Form’
Surprisingly happy in our climate in its native Monterey Bay area of California its known colloquially as Dune manzanita. Very gray blue leaves are not huge and hug the stems tightly on a compact moderately growing Manzanita. To 5′ tall and wider over time. In mid winter to early spring white flowers tinted pink appear in clusters at the tips of the plant. The trunk becomes deep mahogany brown over time and contrasts greatly with the light colored foliage. All around fantastic shrub for full sun and average, unimproved soils with little irrigation once established. Not as fast growing as other Manzanitas, usually less than 5″ per year.Very pretty plant that mixes wonderfully in droughty shrub borders, and even as a foundation shrub. Makes a nice life in a containers for years. Long lived. Probably harbors some deer resistance. Extraordinarily drought adapted. Native to a restricted range on the central California coast. Great performance on the Oregon coast.
Tea, the commercial source of black tea is a fine ornamental shrub in our climate as well. Its more than welcome in autumn when the small cup shaped fragrant white flowers peek from the stems. A rounded, good looking clean shrub with leaves that are deep green with more conspicuous venation on the surface. To 8′ x 8′ in 10 years for light shade to full sun. Great on an eastern exposure. Commercial black tea is produced by the fresh tips of the plant. These then go through a process of fermentation before it is edible. See more research. Easy to grow and somewhat more open than more commonly grown Camellias. And the leaves appear more matte as well. Regular summer water for the most verdant growth. Otherwise it accepts the same conditions as any Camellia. Blooms August to November. Blooms on wood from the previous year, prune if needed after flowering.
Erica mammosa ‘Orange’
This is a tender Erica inland. It prefers the Oregon coast (Zone 9) and it performs there wonderfully. A large growing S.African heath that displays copious large tubular orange flowers from Aug-Nov. Excellent potted plant if you protect it from temperatures below 20ºF. Move to an unheated garage or bright cool room during times of arctic air. To 3′ x 3′ and mounding. Cut flowering stems last quite a while in water. Full sun and rich, to average soil that drains. Regular summer water. Not a particularly fussy plant. Takes coastal conditions like a champ. Spectacular in bloom. Moderate deer resistance. South Africa.
Fargesia dracocephala ‘Long Leaf Form’
Intriguing CLUMPING bamboo that rises to only 6′ tall but arches as wide. Fine, arrow shaped leaves protrude in the same direction giving an airy symmetry. Takes pruning very well and is recommended for small spots. In the open give it room to arch. The 1/3″ wide culms clusteer tightly forming a moderately fast increasing clump. After 10 years the base of culms will be no more than 2′ wide. Full sun to part shade to shade in rich soil with consistent summer irrigation. Established plants can take far less. Wonderful in a woodland or as an asian accent in themed gardens. This is a very hardy bamboo- tolerating temperatures slightly below 0ºF. A great bamboo for those in the line of east winds. Plant on 3′ centers for a dense hedge. Prune in spring if needed or allow it to gently repose with natural grace. Moderate deer resistance. SW China.
Rosmarinus (Salvia) officinalis ‘Hardy Prostrate Form’
You might be surprised to find that some Rosemaries are tender to cold. In general the clones of prostrate forms are less hardy. This is cuttings from a low growing plant that has weathered the coldest winters of the past 10 years- so we’re confident its reliable. Mounding evergreen shrub to 2′ tall x 6 wide in time. The branches closely follow the contours of anything in its path and is fetching as it trails over rock walls, boulders, anything that gets in the way. Soft blue flowers almost year round but peaking in the winter. Little water needed once established in soil that drains. Water to establish or to speed growth. Wonderful herb for cooking. Takes the hottest, most blasting sites with no stress. Moderate deer resistance. Excellent on steep slopes as it will root where stems touch the ground- important for erosion control. Very pretty planted with yellow flowered Grevillea juniperina ‘Molonglo’. Similar cultural conditions and concurrent bloom. Syn Salvia rosmarinus). Full hot sun.
Ceanothus thyrsiflorus ‘Umpqua Sky’
A very large growing, vigorous and pretty tree type Ceanothus native to the extreme SW part of the state. This fast growing evergreen tree (3′-4′ per year) puts on a huge display of soft blue flowers in late April to early June. Full sun to light shade (high overhead shade) and average soil that drains. Adaptable to clay soils, especially on slopes and not watered at all in summer. Completely drought adapted, no water necessary once established. To 18′ tall and half as wide in 7 years. Great screen, blue flowered tree that is beautiful in bloom but fades to a background for the rest of the year. Prodigious pruning can keep it much lower and it makes a great large hedge in no time. Good cold hardiness to 5ºF. We chose this variety in the wild because it was found quite a bit away from the coast which increases cold hardiness and it was immensely heavy in bloom. Prune AFTER flowering if needed. As a hedge or smaller plant it only requires pruning once a year- especially if strictly unwatered. Extraordinarily heavy bloomer and the trusses of flowers are often divided into six or more sub-branches for a very full look in bloom. Pairs well with Madrone and Arctostaphylos. Oregon native plant.
Xera Plants Introduction
Arctostaphylos edmundsii ‘Big Sur’
This handsome low growing and compact Manzanita has great performance in our climate. Glossy mid-green foliage clothes a dense growing plant to 2′ x 4′. Admirable low ground cover as a massed subject but individual plants have glossy mahogany trunks that develop character with age. Masses of small light pink urn shaped flowers appear in late winter to early spring. Healthy looking at all times and not prone to black spot. Takes reflected heat well and even tolerates a light amount of shade. No water necessary once established, but it will take light water on slopes. Great small scale for small gardens. In time you can lift the plant up by pruning to reveal the small trunks. Long lived. One of the finest smaller varieties. Central CA coast.
Slender Monkey Flower is the inland version of the coastal varieties. AKA Azalea flowered Monkey Flower this subshrub blooms continuously through the season with soft apricot colored tubular flower. Blooms May-August- sometimes later. Average to enriched, very well drained soil- excellent on slopes and rock gardens. To 30″ x 30″ when really happy. Loved by hummers and west coast pollinators in general. This species ranges from the coast to the Sierra Nevada in CA- this form is from colder inland areas and is easier to overwinter in our climate. Forms a semi-woody sub-shrub. Cut back the plant hard after all danger of frost has passed. Not palatable to deer. wonderful long blooming plant for low water to no water landscapes. Light summer water increasing blooming but is far from necessary. Many of the apricot flowers are pictoteed in white for an almost florist quality. Thrives in the wild following fires, disturbance. Butterfly food. West coast native- California.
Willamette Valley white Meadowfoam is such an unassuming plant with an incredible tough streak. Finely divided grass green leaves are completely obscured by the copious cup shaped white flowers. Opulent bloom begins in April and extends to early June. Forms connecting mounds that knit together into one sheet of ivory petals. Native to the central and southern Willamette Valley. It can be seen occasionally on road cuts and the gravel on street margins. But planted en masse it is spectacular. Excellent plant for tough, compacted, clay soils. To 4″ tall and each plant is about 1’wide. Leave spent dried stems where you want the next years display to be. Germination in autumn precedes most cold season weeds and forms an effective cover crop. Though prolific its well behaved enough to live between shrubs and even perennials. Excellent mixed with Baby Blue Eyes and Yellow and white Limnanthes douglasii. Water containerized plants at installation then none necessary. Self sown seedlings are MUCH more drought adapted and can germinate on soil as hard as concrete. Moderate deer resistance. Beautiful native wildflower.
Agave ovatifolia ‘Frosty Blue’
A real winner in our climate this is perhaps among the easiest bold Agaves to cultivate. Large rosettes of flared deadly leaves are a luminous light blue. The whole rosette can achieve 3′ wide and nearly as tall but smaller is more common. Excellent tolerance of the combination of cold and wet that Agaves mostly despise. This plant also is less prone to injury from necrosis of damage- slugs, snails etc. Full sun to a surprising amount of shade, though you’ll want to avoid the overhead detritus of trees into the rosette. In full sun such as a bare parking strip it revels in heat, exposure and fast drainage. Amend the soil to at least 1/2 pumice and 1/2 virgin native soil. Water to establish then only what falls from the sky. Obviously site away from paths- stab wounds suck, literally. In Mexico they planted large agaves in front of the bedroom windows of their female children. The idea I guess was to deter suitors with bad intentions. But its a neat story and you could see how it would work. Obvious awesome deer resistance. Sometimes called Whale Tongue Agave.
Watsonia x pillansii ‘Coral and Hardy’
We love Watsonias but the most successful climate is truly on the coast. This form is seed from a persistently hardy, well blooming plant that has survived in Portland. The majority of these seedlings will be coral/ orange/ light pink. To 20″ tall forming clumps in RICH, well composted soil in full sun. Regular summer water increases both the growth rate and the cold hardiness. Larger more established clumps are hardier to cold. Amazing cut flower that will produce several dozen spikes off of one good clump. Mostly evergreen. Foliage looks burnt below 20ºF and can freeze to the ground. This winter growing bulb is also immensely drought tolerant with a period of summer drought inducing dormancy. Place in a warm, protected location Near a south facing wall or fence. Mulch for the first few winters with dry leaves. Place in a location where summer dormancy is not an issue. Very fun to grow South African bulb. Excellent performance at the Oregon Coast. Not bothered by deer or elk- well the elk might step on them but they won’t eat them. Fantastic cut flower and clumps become huge there.
Xera Plants Introduction
Globularia repens ‘Nana’
Tiny, minute, so small the paddle shaped deep green leaves of this tiny groudcover hug the ground so tight you might over look it. In April/June you won’t miss the masses of relatively large fluffy steel blue globe shaped flowers that float above the plant. Excellent plant for massing in rock gardens, hot dry sites anywhere with full sun and free drainage and protection from marauding invaders. To 2″ tall in bloom a well grown patch can stretch several feet across. Gritty soil that drains quickly. Regular summer irrigation increases the growth rate which is never rapid. Adorable plant that creates a carpet of color and texture. Great plant for alpine troughs where you can keep an eye on it. Fairly spectacular in full bloom. Loved by bumble bees and bees in general. Classic rock garden plant. Native to the mountains of southern Europe.
Arctostaphylos glandulosa ssp. glandulosa ‘Demeter’
Our employee Adinah spotted this distinct form of our native glandular manzanita in extreme SW Oregon. This form boasts very silver foliage with sharply pointed leaves and the conspicuous glands that identify the species. In mid winter to early spring clusters of pink buds open to pendant urn shaped white flowers. Loved by over wintering Anna’s hummingbirds. A low and spreading Manzanita to 4′ tall by 6′ wide in 7 years. Not as rapid of growth as other varieties. Full sun and average, well drained soil. Do not amend the soil but rely on our own native soils perfect fertility. To further enhance success double dig a wide area around the plants new home. This incorporates oxygen into the soil in a wide area and also allows the percolation of water. Mulch after planting with a coarse bark. Very pretty, very gray dome shaped shrub which eventually reveals contrasting mahogany glossy peeling trunks. A very pretty species that is uncommon in Oregon but whose range extends south all the way to Baja Norte. Once established, do not water- neglect and perfect climate adaptation will do the rest. Oregon native plant.
Xera Plants Introduction
Camellia x ‘Coral Delight’
Brilliant flower color cast on huge semi-double flowers are but one advantage to this handsome evergreen shrub. An upright pillar shaped habit makes it a great plant for tight spots or as a hedge or screen. To 8′ tall by 3′ wide in 8 years. The enormous 5″ wide opulent flowers are a a clear and ringing coral. Showy from quite a distance and the entire shrub is clad in blooms from late January to March. Glossy pointed foliage is handsome year round. Somewhat formal dense habit lends it to small gardens, structural shrub. Full sun to quite bit of shade in rich to average soil with regular summer water for the first several seasons. Benefits greatly from a layer of mulch after planting. Tosses its spent flowers which do not cling and discolor. Excellent shrub for Japanese themed gardens. Long, period of bloom.
Camellia x williamsii ‘Little Lavender’
Interesting, hardy, and very bloomy Camellia that enchants us with anemone style flowers with a distinct lavender cast. Upright growing shrub to 8′ tall by just 3′ wide in 7 years. Glossy foliage looks good year round. Full sun to quite a bit of shade. Regular water to establish then deep and sporadic during summer. Excellent skinny Camellia for tight quarters. Takes quite a bit of summer drought when established. Excellent tolerance of sub-freezing wind and this upright plant would make a showy hedge or screen. Little pruning needed. Flowers shatter cleanly, never clinging and discoloring- one of the best traits of any Camellia. The lavender hue of the flowers is most pronounced in full sun. The ‘Little’ part of the name refers to the size of the adorable flowers which appear en masse February-March.
Grevillea x ‘Xera Red’
A very interesting Grevillea. This is a seedling of ‘Marshall Olbrich’ that appeared in my former garden. For the past 13 years its thrived in that garden reaching 5′ x 6′ forming an open spreading shrub. The evergreen leaves are soft gray on the underside and distinctly pointed. True red flowers appear year round and are a beacon to all hummers. Handsome shrub that has shown consistent hardiness and ease of culture. Full sun and average, native, un- amended soil. Plant this shrub and water until you see good new growth then taper off. For rapidly growing shrubs tip pruning controls not only the size but encourages root stability AND promotes flowering. Prune after a large flush of flowers. Full sun to very light shade in a warm position. Avoid subfreezing wind exposure. In those areas of east wind locate on a south or west facing aspect. Best true red flowers as of yet on a hardy hybrid. Mulch after planting with bark or gravel. Drought adapted when established. Limited quantities. Absolute hummingbird dream.
Xera Plants Introduction
Rhaphiolepis umbellata var. minor
Excitement doesn’t really well up with this genus. The reason we grow this plant is that it is healthy, drought adapted, and handsome all the time. And its a great scale and is slow growing. Dense evergreen shrub with wavy deep green foliage. New growth is conspicuously tinted red. In spring clusters of pure white flowers are pretty if not enough to stop a car. To 3′ x 3′ in 8 years. Yep. Slow growing and a great size for full hot sun to light shade and rich to average soil. Drought adapted when established it will also accept regular irrigation. Somewhat formal appearance and a great backdrop to other plants. A nice formal hedge plant or left to its own devices an informal hedge. Clusters of blue berries often follow the flowers and are added interest. NOT DEER RESISTANT. Rose family. Excellent performance in tough urban sites. Including unwatered parking strips. Grouped tougher it can form a low groudcover (3′ high). Regular water to establish. Dwarf japanese yedda hawthorne.
Foothill Sedge is commonly found from the central Willamette Valley south into California. A tightly clumping sedge with medium green foliage and 8″ wiry stems with attending flowers that are tan in spring/summer. In our region this plant can be found in upland situations where it is moist for at least half the year. Its also diminutive and almost hard to find in the wild. Under cultivation its an entirely different beast. Clumps are dense but expand with a pronounced weeping habit. To 8″ tall x 18″ wide for each individual plant. Good massed or as a lawn substitute. Takes mowing if its limited to once a year. Regular irrigation keeps it green and happy. Summer drought sees blades of tan as well as green and not so verdant. It does not run nor become a seeding pest- sticking surprisingly to itself. Plant on 1′ centers for a modern, mounding effect. Takes clay soils well. Water regularly to establish the first summer then taper off (continue watering if you want it to stay staunchly green). Combines well with perennials including native perennials such as Checkermallow (Sidalcea) and, Ranunculus occidentalis (Western Buttercup), as well as Shooting Stars (Dodecatheon) are found in closely related communities with this plant. Full sun to light shade, or high overhead shade. In California it is also known as Berkeley Sedge. Oregon native plant.
Ceanothus thyrsiflorus ‘Oregon Blue’
This form of Blueblossom we found on the southern Oregon coast in the far northern part of Curry County. There seems to be two forms of Ceanothus thyrsiflorus in Oregon. The immediate coastal species up to Lane county has broader leaves. Inland you find a much taller form with smaller juvenile leaves. An example of this is our large selection ‘Oregon Mist’. This is the standard broad leaved form you find adjacent to the beach. Glossy rounded leaves are lustrous and deep green year round. In late April to early June an extended period of profuse sky blue flowers. Adored by pollinators and rolling in grateful bees. A large native shrub with a rounded outline. To 8′ tall and possibly a little wider in AVERAGE soil in 5 years. Amended soil leads to prodigious growth and lack of hardiness. Fast growing low water shrub for full sun to very light shade. This plant that we collected in the wild is actually very similar to the cultivar ‘Victoria’- the primary difference is earlier bloom by several weeks. And a slightly lighter blue flower. This is a good standard form of the beach species as found in our state. Its been cold hardy to 5ºF with good pest free foliage. Ceanothus fix nitrogen with their roots and improve the soil. Also, years of detritus from the shrub collects to form wonderful enriched soil as well. Average life span increases the less this plant is watered once established but expect 9-15 years. Durable shrub for urban to rural places. Extraordinarily drought adapted as well as tolerant of dry clay. Pretty and utilitarian. Available, autumn 2020. Oregon native plant.
Xera Plants Introduction
Rosmarinus (Salvia) officinalis ‘Ticonderoga’
Hard to believe that Rosemary has been officially lumped into the genus Salvia. (Sigh). Its still a wonderful shrub and this variety delights us with the MOST luminous blue flowers that we’ve seen on a hardy variety. The effect is similar to the slightly tender cultivar ‘Tuscan Blue’. Each flower is luminous and they obscure the leaves for most of winter into spring. Upright growing cultivar that spreads with time. To 4′ tall x 4′ wide in short order. Full sun and soil that drains with little summer water once established. It will take moderate irrigation as well but we like to rely on the iron clad drought resistance of this culinary herb. Mix with Arctostaphylos, Grevilleas for a shrubby winter blooming party. Very easy to grow. Nice informal or even clipped dense hedge. Develops a handsome gnarled trunk with time. Moderate deer resistance. Salvia rosmarinus.
Hebe x ‘Chehalem Purple’
One of our very wonderful customers gave this plant to us. She’s been a loyal customer for years and in that time I’ve known her to be keen with observation and details. Which is why I immediately accepted this plant. It was seedling in her garden and it had thrived for many years with nary a scratch from cold or disease. The uniform deep green foliage has an underside of madder red and the stems share that hue as well. When cold weather arrives the entire plant takes on maroon/burgundy tints. Very pretty. In August-November a prolonged show of vibrant purple flowers appear all along the tips. These cones of flowers are vibrant and are set perfectly against the deeply colored foliage. To 30″ x 30″ in 5 years. Full sun and soil that drains. Light consistent summer water ensures health. It has survived temperatures slightly below 10ºF so far with no incident. Handsome, showy Hebe for our gardens with a proven track record. Remarkable local Hebe selection.
Xera Plants Introduction
Grevillea victorae ‘Murray Valley Queen’
A vibrant form of Royal Grevillea that is slightly less hardy to cold than the species and requires a protected spot. Why grow this variety? It blooms, and blooms, and blooms. Rusty orange buds decorate pendant clusters that open to fresh orange. This plant sets tons of buds in summer and then releases them to the public through all the months of winter. Slightly smaller leaves are dusted in brown indumentum when young. To 8′ x 8′ very fast in average, unamended soil where water does not linger. Best in urban gardens with extra heat. It does not abort as many, if any flower buds in the summer drought. Excellent performance at the Oregon coast. Rounded upright and spreading evergreen shrub that remains handsome year round. Prune if needed after the last flush of flowers in spring. Winter flowers are a beacon to Anna’s Hummingbirds. Native to Australia where it was discovered near the Capital of Canberra. Nice cut flower. Water to establish then taper to once a month in summer. In colder gardens locate under the canopy of tall trees or near a warm wall. Full sun to light shade.
Banksia marginata ‘Minimarge’
MINIMARGE! This is a dwarf form of Banksia marginata that has been cold hardy in the Portland area. The key to cold hardiness is to establish the plant well. Unlike other members of the Proteaceae this small shrub likes the soil a bit richer, but that drains well. You can even add a small amount of compost when planting but nothing other than that. Water it until you see good new growth then taper off to once every two weeks. Full sun, in a warm, protected location. A south facing slope with protection from east wind is ideal. To 3′ x 3′ in 7 years. On older wood 4″ tall yellow cones are produced as flowers from spring to autumn. Protect young plants from severe cold. Very good performance on the Oregon coast. In time it will form a small lignotuber. A swollen woody base with dormant buds. It may then be cut back fairly hard and re-growth will commence. Avoid crowding this plant with others. Open and happy is how it likes to be. Great plant for a large rock garden. Hummingbirds adore the spectacular long lasting flowers. Foliage is deep green with an underside of silver and forms winding stems- never tidy. A plant for collectors primarily. This is not a plant for beginners. Heh. Avoid all fertilizers. Limited supply.
Holboellia angustifolia (Heronswood)
We got this form of Holboellia from Heronswood eons ago. It has much larger leaves than those being sold as angustifolia, And it bears larger flowers too. A vigorous, hardy, evergreen vine applicable to a large pergola, fence, or sturdy arbor. Twining vine to 20′ or more over time. On wood from the previous year large clusters of pendant white flowers have a soft sweet fragrance in close proximity. We have yet to see fruit set on this particular cultivar. Good year round appearance, not roughed up by winter in most years. The large palmate leaves are held on sturdy petioles that separates the whole leaf. Full sun to shade in rich to average soil w/ regular summer irrigation. Takes very dry conditions when established. Provide STRONG support- established plants can put on many feet of growth per year. Elegant layered appearance of the leaves gives this plant a graceful mein. Prune AFTER flowering if needed. You can prune it hard in late winter – this will sacrifice many flowers but re-growth is vigorous, if not instant. SW China.
Rhaphiolepis umbellata ‘Emerald Waves’
Our selection of the tough and adaptable evergreen Yeddo Hawthorne. Each glossy, thick rounded leaf on this cultivar is wavy (undulate) and gives this smaller shrub extra substance. In spring large clusters of pure white flowers cover the whole plant. Often showy blue berries follow. Great resistance to black spot- the best of any we’ve grown. Full sun to very light shade in average to enriched soil. To 3′ x 3′ in 6 years. A long lived shrub that tolerates a great amount of summer drought but greets regular irrigation with equanimity. A frequent component of Japanese style gardens for its simple and clean habit. Takes blasting heat very well, including blazing western exposures that are shady for most of the day. Cold hardy to 5ºF or briefly lower. Great low water landscape plant. Rose family- not deer resistant. Japan.
Xera Plants Introduction
Callistemon (formerly sieberi) pityoides ‘Moonlight’
We’ve grown this plant for almost 20 years. In fact I got my original plant in the 1990’s from a rare plant dealer in Vancouver, BC. This fine textured shrub has needles posing as leaves that densely line the lithe arching stems. In early summer the whole plant is alight in 2″ moonlight yellow colored brushes. A hummingbirds dream. Following hot summers it may repeat bloom in autumn. To 3′ tall by 4′ wide with a somewhat twisted habit. Following the bottlebrush flowers small woody seed capsules line the former blooms and persist sometimes for years- it adds interest to this already interesting shrub. Very deer resistant and accepting of quite dry conditions once established. Foliage takes on bronze tints in very cold weather. Grows moderately fast to its ultimate size. Well sized for smaller gardens. Requires full sun- at least 6 hours per day for best bloom. Prune AFTER blooming if necessary. Blooms on wood from the previous season. Alpine Australia.
Dianthus ‘Pink Pyrenees’
We received this as a gift from the O’Byrnes who aside from breeding the very best Hellebores on the planet have a garden that is to die for. Drifts of Erythroniums, Trilliums, Epimediums, Pacific Coast Iris wash around dry rock areas. Thats where you will find this compact growing but wildly floriferous species pink. The O’Byrnes collected the seed of this fragrant soft pink wildflower in the Pyrenees. And after years of attempting to find the exact species we have given up. So ‘Pink Pyrenees’ is the name. Beginning in late April and blooming solidly until mid june the 8″ wiry stems support subtle clove scented flowers. Excellent in small bouquets, you can cut a bunch and not even notice- so prolific are the blooms. Full sun and lean to gritty soil with light consistent summer water. Takes dry conditions when established. The blue green leaves form a tight bun less than 1′ wide in several years. Deer leave the foliage alone but will nosh on the flowers.
Oregon Sunshine is the cheery common name that greets this widespread native perennial. Silvery gray intricate foliage forms a spreading mat. In late spring and early summer brilliant golden yellow daisy flowers spangle 10″ stems. Loved by pollinators and we’ve been impressed with its draw to butterflies as well. To 2′ across and excellent on slopes where water never lingers. Add compost and this perennial will soar- give it room in that case.In the wild its a frequent of road cuts and other disturbed sites. It also competes admirably with exotic invasive weeds and will persist where other natives are swamped. Rock gardens, dry borders. Water to establish- the first season- but never boggy. The following year it will rely only on what falls from the sky. Full sun to light shade. Adapts to poor soils. Moderate deer resistance. Goes quickly dormant following bloom. Native to the Portland city limits. Very good planted beneath Pinus ponderosa var. benthamiana Pacific Ponderosa Pine this pair can frequently be found in the wild. Oregon native plant.
Callistemon viridiflorus ‘Xera’s Hedgehog’
We love this cold hardy species also known as mountain bottlebrush. This is our selection of a dwarf form and it achieves a very dense, compact habit at just 2′ tall by 3′ wide in 7 years. In May/June 1″ acid green bottlebrush flowers illuminate the tips of the branches. Pollinated by birds in nature it is a beacon to our local hummingbirds as well. Following the flowers rows of button shaped seed pods become woody and add to the shrubs interest. Full sun and rich to average soil with light consistent summer water for the first few years. It can tolerate regular irrigation but is summer drought tolerant when established. A great plant for foundations, rock gardens, hell strips. The pointed forest green foliage takes on maroon tints in the coldest weather. Cold hardy to 5ºF. Moderately deer resistant.
Xera Plants Introduction
Iris x pacifica ‘Multiplicity’
One of the most striking pacific coast cultivars. Large somewhat flat flowers are a saturated orange/ rust color with contrasting purple nectary guides. Excellent plant that is not only extraordinarily heavy in bloom it blooms the LONGEST of any PCI that we grow. Often repeat blooming 1-3 times following the grand first display. Grassy evergreen leaves form spreading clumps to several feet wide. The large flowers rise on 10″ stems. Loved by pollinators. This intense flower color and propensity for heavy bloom endears this wonderful cultivar to gardeners and its often on the list of favorites. Full sun to light shade- ideally it may be grown best in an open north exposure. Such as the north side of a house with no overhead shade. Blooms late April-early June. Very deer resistant. Water consistently through the first summer than none in subsequent years. And once established it resents disturbance.
Prunella vulgaris var. lanceolata
As a child in the country near Eugene western self heal was one of the first wildflowers I learned to identify. And its a beautiful and fascinating native perennial. This ‘weed’ circles the world but our locally native form is an exceptional improvement. Lance shaped basal leaves (the trick for identifying our local sub-species) forms stout upright stems. They are crowned with ‘cones’ that have whorls of showy deep purple tubular flowers- they appear continuously for up to 6’weeks into August decorating the tops of a 1′ tall plant. Spreads to form a clump as wide and appreciates average to enriched soil in full sun. Regular summer water increases vigor and lengthens the bloom time. A very charming native cut flower that produces new blooms continuously after its picked. This is a very important plant for native pollinators. Also, it differs from the pan-weedy form in larger cones and much showier flowers. Its a larger plant as well. Adapts to clay soils with regular irrigation to establish. A natural magnet for butterflies. Blooms May-August. In our region it is now found primarily away from the valley in upland valleys to alpine meadows and scree. A good native weed that is a great garden plant as well. Oregon native plant.
Rosmarinus (Salvia) officinalis ‘Carollina’
This beautiful, deep sky blue flowered rosemary we found planted at a 100 year old farmhouse in Milwauke, OR. The flowers are scintillating and this plant- installed in the early 1980’s, has proven longevity as well. To 3′ tall by 5′ wide eventually. Blooms appear unabated from autumn to summer. Vigorous evergreen shrub with an upright and then spreading habit. Full sun and no water necessary once established. It can take light, regular water in summer as well. Otherwise, it thrives on only what fall from the sky. A very showy winter blooming shrub for hot locations, south facing hillsides, adjacent to walls, asphalt anywhere another less heat durable plant would fry. Moderate deer resistance. Pungently aromatic and great for culinary use. Prune- if needed, in late spring following bloom. Blooms on wood from the previous season. This variety would make an admirable upright, clipped hedge. Named by and for our friend Carol. Thanks Carol. Salvia rosmarinus.
Xera Plants Introduction
Erodium ‘Pickering Pink’
‘Pickering Pink’ Cranesbill. The name sounds like it will have an all pink flower. Not really. The simple five petalled flowers have two petals that are pink on top with a distinct black blotch. The two lower petals are soft pink almost white. This contrast of colors gives this small plant extra impact as well as a fun wild flower appeal. It forms a tight mound of soft, divided foliage to 3″ tall by 10″ wide. The cheery flowers are born on 6″ wiry stems. Blooms appear continuously from mid-spring to frost. Erodiums bloom and bloom with little intervention from the gardener. They also excel in the rough life of hellstrips. In borders, rock gardens, containers, even small meadow gardens this European native is excellently adapted to our climate. Light summer water increases the flower display and spent flowers can be snipped to not only spur more but to achieve a tidier look. Evergreen foliage and low stature also make it appropriate between pavers. Some deer resistance as well as rabbit resistance. Very easy to grow. Full sun.
Pelargonium ‘Vancouver Centennial’
One of the very finest Pelargoniums or (Geranium- annual) with stupendous jagged foliage and vivid flowers. Each palmate leaf has a center of dramatic bronze and is outlined in bright chartreuse green. The star shaped hot orange flower is a bright and elegant contrast with this foliage. Compact growing habit. Excellent seasonal container subject or even bedded out. To 20″ x 20″ by the end of the summer. Rich, well drained soil with light consistent summer moisture. Remove spent flower spikes to tidy, encourage more. Moderately deer resistant. Avoid over watering. This Pelargonium is a VERY HEAVY FEEDER. Use ample amounts of all organic fertilizer. It also responds to foliar feeding with liquid fish. But fertilizer is essential. Easy, striking plant and our favorite Pelargonium.
Aloiampelos (Aloe) striatula
We’ve grown a lot of Aloes with purported cold and wet hardiness and this is the one that has been the most successful. A large succulent shrubby plant with rosettes of deep green succulent foliage. In late summer to autumn a showy display of large yellow flower spikes can occur. Very pretty and loved by all nectar seeking folks. Give this South African perennial VERY GOOD DRAINAGE in full sun and a warm position. A slope is always helpful. Amend the soil with plenty of gravel and sand as well as compost- these guys do need to eat- so a little handful of organic fertilizer is recommended. Capable of freezing to the ground (below 15ºF) and resprouting from the base when truly warm weather arrives. Plant on a south or west facing slope preferably against a warm wall or boulder for added reflected heat. Easy, if large, container plant that you should protect from temperatures in the teens. To 3′ x 3′ on average in our climate. Mostly evergreen here. Combine with Agave, Cactus which will also increase their growth rate if you provide light, consistent water during hot weather.
Achillea millefolium ‘Salmon Beauty’
Yarrow is an unbeatable native perennial that blooms for a LONG time with a minimum amount of effort from the gardener. Foamy, ferny gray green leaves creates a low carpet of evergreen foliage. Rising up on 2′ spikes flat umbels of soft salmon flower create landing pads for pollinators. The flowers fade lightly after opening for a wonderful multicolor effect. Remove spent flowers, apply a little water and it will repeat bloom until frost. Best in lighter soils that are enriched but drain quickly. Best floral displays occur with light consistent summer water though it is very drought tolerant when established. Tolerates the toughest, hottest sites. Admirable if a little pungent cut flower. LOVED by pollinators. Creates a growing patch to several feet wide quickly. Blooms spring- autumn. Moderately deer resistant. Borders, dry borders, hell strips, etc. Oregon native plant.
Carpenteria californica ‘Elizabeth’
A wonderful selection of Bush Anemone that was chosen because it produces more flowers (though they are a tad smaller than the species) born in multiple sprays. And this form is slightly more compact as well. An evergreen shrub with lanceolate leaves w/ a rolled margin (revolute). The deep green leaves are attached to tan stems and trunks that with age exfoliate to a glossy metallic sheen. To 6′ tall by 4′ wide in 5 years. Full hot sun to very light open shade in average, well drained soil. For clay soils its best planted on a slope. Water to establish then none after the first summer- in fact this extremely drought adapted shrub prefers to go with out water. Provide good air circulation. Adaptable to the hottest sites, including western and southern exposures. Moderate deer resistance- they will try young plants so protect them. Long lived, climate, adapted shrub. Cold hardy to about 0ºF. The white flowers that occur in May/June are sweetly fragrant. Prune, if needed AFTER flowering.
Leptospermum scoparium ‘Washington Park’
Manuka. This is a wonderful very upright wispy evergreen shrub with tiny leaves that turn maroon in winter and masses of white flowers in early summer. Flowers are born on wood from the previous season and are much larger than the foliage. The effect in early summer is a shrub clad in snow. To 8′ tall x 4′ wide in 5 years. Full sun and a protected position, such as against a south facing wall. This form is from the Washington Park Arboretum in Seattle where it has thrived for many years. A selection made from high elevation inland New Zealand. Grows very fast w/ light summer water. Excellent fine textured plant. Moderate deer resistance. Cold hardy to a little below 10ºF- it has been damaged but recovered from lower temperatures. Very easy to grow wild looking plant. Drought adapted when established.
Eschscholzia californica ‘Jelly Beans’
Spectacular mix of double flowered California Poppy in shades of pink, yellow, apricot, rose, red, orange, and yellow- and more colors than that. Easy to grow plants that can even be perennial if happily sited and cared for. Otherwise an incredibly showy annual that also makes a great cutflower- cut in bud and they will last several days. Sophisticated selection of our own native poppy and they will most likely reseed in open disturbed sites. Blooms May-August and sometimes longer. Remove spent flowers to encourage more. Leave the final round of blooms to set seed for the following season. To 1′ x 1′ with beautiful lacy glaucous foliage. Rough areas in full sun with light summer H20. Highly deer resistant. Oregon native plant.
Passaflora x caerulea ‘Damsel’s Delight’ ®
Fantastic new hybrid Passion vine with impressively huge, spectacular flowers and a more restrained habit. 4″ wide brilliantly colored flowers feature deep blue and purple and white alternating stripes on the row of filaments that encircle the center. The sepals- petal like structure surrounding the flower alternated between white and lavender. To only 8′ tall in a season and remaining compact for all of its life. Happy evergreen vine that climbs by tendrils.- provide support. Small enough to find a long happy life in containers. Rich, well drained soil in full sun and a warm position. Evergreen to about 15ºF- the vast majority of winters. This passion vine has the largest flowers by far of any cold hardy selection. Truly beautiful and impressive. Flowers emit a light sweet scent and we have yet to see fruit produced. Loved by children and adults as well as the occasional butterfly. Blooms on the current seasons growth. Prune whenever you feel like its necessary- rare for this compact and easy vine.
Passaflora caerulea ‘Becky’s Blue & White’
Blue crown passion vine is an incredibly popular if huge vine in our climate. This form has the typical 3″ intricate flowers with the tinker toy center but the filaments that encircle the middle are deeper blue w/ a contrasting zone of brighter white. The result is bolder coloration and contrast. Rampant evergreen vine to about 13ºF . The vine is root hardy to about 0ºF- especially when established. Give this big vine room and proper support. To 18′ tall and wide very quickly in average, well drained soil. Evergreen lobed leaves are glossy and this vine blooms profusely on new growth. The more it grows the more it blooms. Winding tendrils assist its climb and will adhere to anything with a diameter smaller than a regular sharpie pen. This includes screen…and if it is too close to a house and they attach to the screen….bad scene getting them off. Otherwise provide a trellis or pergola that can accommodate its size. Flowers appear from May-Frost. It may be cut back very hard in spring to refresh, supply new blooming wood, or just to restrain. Overly rich soil leads to rampant growth and less flowering. So, average soil that drains is ideal. Flowers often transform into golf ball sized orbs that are sweet tasting but not really food. Established passion vines will often sucker quite a way from the parent plant. Plant for this and be vigilant. There is no vine, however so magical in flower form that it transfixes people and is a special joy for children. Little water once established. Deer resistant. Mountains of Brazil.
Solanum (laxum) jasminoides
White Potato Vine is an incredibly floriferous plant. Large and profuse clusters of stunning star shaped flowers are clear white and appear continuously from May to frost and if winter fails to materialize even longer. Semi-tender in our climate it requires protection for the base and rich, well drained soil. Vigorous climber to 12′ in single season. If it freezes the ground- this happens below about 20ºF it can break from the base and regrow quickly. In Portland this happens about every 3-4 years. Climbs by modified leaf petiole and requires substantial support. Personally, I think the best way to grow this everblooming vine is in containers, even window boxes where the plant will become a trailing cloud of white stars for months. Blooms on new wood, it may be pruned at anytime. Mulch the base in fall with compost or leaves and place against a warm wall or in-between close shrubs that will bolster further protection. Loved by bees and bumbles. Regular deep summer water produces the best results. Full sun to very light shade. Spectacular performance on the Oregon Coast. Native to Chile/Argentina.
Dianthus x ‘Eileen Lever’
Eileen is a little bun of fun. A tight mounding Dianthus that forms a dome of prickly blue/green foliage 8″ wide and just 2″ tall. In May-June this foliage is obscured by a solid mass of brilliant pink flowers. They emit the treasured clove fragrance so loved in this genus. A first rate rock garden perennial, or for troughs or even amenable with drainage to the front of borders, dry gardens and even Hellstrips. Gritty soil is what most dianthus buns crave, and you can achieve this by simply amending the soil with a handful of sharp gravel. Otherwise this cuties is adapted to not many nutrients but must have full sun. Light consistent summer irrigation makes the slowly expanding bun speed up. Just a touch. Not difficult and stunning in bloom. Buns, we love the buns of fun. Thanks Eileen. Evergreen. Cut off spent flowers for a clean and neater appearance. Very good to try where bunnies and deer are an issue. They tend to completely overlook this plant. Long lived perennial.
Viola ‘Tiger Eye’
We grew this just for fun last year and not only was it one of our most talked about plants it became one of our favorites as well. Each yellow/gold/burnt umber flower is intricately and completely marked in black lines. On very close inspection they almost look like a drawing of flowers. And its the most FRAGRANT viola we’ve ever smelled with a sweet perfume that carries quite a distance. Compact hardy annual to 6″ x 6″ for full sun to light shade. Excellent tolerance of cold (down to zone 7) as well as heat. All around its a winner of a viola, for containers, borders etc. Blooms non-stop, removing spent flowers does encourage more. Stop and smell the Violas and then stare at the patterns. Its a trip man.
Anchusa azurea ‘Dropmore’
Alkanet, Italian Bugloss- neither name is very appealing but I’m here to testify that if you are a connoisseur of the color blue this big showy perennial is for you. To 4′ tall multiple spikes bear rich, deep, true blue flowers in one bodacious cloud. This form is not only a superior blue, but its a more reliable perennial. Most live 2-3 years but this often persists for longer. This borage forms a basal rosette of rough leaves- this is important to identify the inevitable seedlings- they are dark, dark green and spiny. Blooms first year from seed. A Spectacular plant for a young garden, a dry garden, wild border or in its most classic home the cottage garden. Full sun and average to enriched soil that drains quickly. Light consistent water to establish then drought adapted. Long, long blooming plant that often has bumble bees fast asleep in the cup shaped flowers. Very cool. Obvious pollinator gem. Very climate adapted plant.
Lewisia cotyledon ‘Rainbow’
This strain of our native Siskiyou Lewisia contains a stunning range of flower colors. Pink to orange to white to yellow and permutations in-between. One of our most cherished wild flowers this plant is found at high elevations in the southern part of the state. A succulent that forms an evergreen rosette it displays its flowers for literally months on end beginning in spring. Excellent, long blooming, easy to grow container plant but not difficult in the ground given rock garden conditions. Drainage is crucial, in average to enriched soil. Drought adapted but it blooms longer with light summer water. Full sun to very light shade. Excellent at the top of walls, spilling out of cliffs as it does in nature. To 6″ tall forming multiplying rosettes up to a foot across. Moderate deer resistance. Oregon native plant.
Lavandula x lanata ‘Ana Luisa’
So many lavenders that we’ve decided to go with the very best. This hybrid is a cross between english lavender (L. angustifolia) and wooly lavender (L. lanata) and gives you wonderful almost white wooly foliage with deep purple thick flowers. To 2′ tall and 2′ wide in time this rounded evergreen shrub blooms for an incredibly long time beginning in early summer. Full sun and rich to average soil with light but consistent summer water. Very easy to grow in our climate. Shear the spent flower spikes and cut into about 1/2″ new growth for a compact and more densely blooming habit. Excellent landscape plant, informal hedge or specimen in a border. This Lavender looks good year round- better winter appearance than most. Lightly deer resistant. Not their first choice but not 100% immune to browse either. Aromatic foliage. Wonderful white foliage contrasts greatly with deep green foliage for depth in plantings. Bred and named by Andy VanHelvingen of Vanhelvingen Herbs.
California meadow sedge is native to stream banks, and vernally wet places at the beach from British Columbia south in to Baja. A deep green winter growing sedge which each plant reaches about 18″ across and 10″ or so inches high. It flops over gracefully and has a very uniform appearance through the year with light irrigation. This is a winter growing plant that resumes growing and greens up with winter rains. In very cold weather (below 20ºF) it can take on russet tints. A FANTASTIC LAWN SUBSTITUTE where it has been used extensively for that application in California. We should use it here too. Plant on 1′ centers for a lawn (faux lawn) cover from one gallons and water regularly through the first season. No water plantings can go summer dormant but in wetter environs this can be avoided and it will remain green and verdant. Water once a week in summer to remain green. Fantastic ground cover, slope cover as it will out compete weeds and form a uniform cover. Tolerates clay soils well, but some amending will reap rewards with a faster growing plant. Tolerates mowing very well. Oregon native plant.
Rosmarinus (Salvia) officinalis ‘Portland Violet’
After almost 30 years of selling plants I can say that usually the first plant to go into a garden is Rosemary. And why not? It loves our climate. Its drought tolerant beyond measure and heck its even edible. And that fragrance. One thing you might not think of is winter flowers. This form from an ancient plant that has unique flowers. From September to June it is alight in clouds of soft violet blue flowers. Flowers all winter! Excellent as a specimen or hedge. This cold hardy variety can inhabit the coldest gardens. And my god there is always pork. To 3′ tall x 5′ wide in 10 years. Full sun and average soil that drains. Light to little summer water required. Moderate deer resistance. Salvia rosmarinus
Xera Plants Introduction
Camellia sasanqua ‘Li’l Rose’
Obscure and stunning DWARF Sasanqua Camellia. Beginning in October and opening blooms through December and sometimes even later. Smaller stature than a standard Sasanqua. The double glistening pink flowers decorate the shrub in a dense way. To 4′ x 4′ in 8 years- but growing larger. Deep, deep green glossy leaves are pretty on this open and lax evergreen shrub. Full sun to light shade in rich to average well drained soil; light consistent summer water increases fall bloom set. Excellent and dainty espalier subject. Very pretty blooms.
Grevillea x ‘The Precious’
Excellent introduction from Desert Northwest Nursery in Sequim, WA. This seedling of ‘Leanne’ exceeds that cultivar in several ways. First, it has decidedly smaller, needle-like deep green foliage. Second, its profuse flowers are a brighter and lighter yellow that is showy from a distance and great contrast with the darker foliage. This brand new plant is likely to reach 3′ x 5′ in 8 years. Moderately fast growing. Blooms begin in mid-winter and repeat to autumn. They take a brief break late in the year. They are a beacon to hummingbirds as well as gardeners in the the last cold days of winter. Full sun to very light shade in average, un-amended native soils. Good drainage is helpful. Very little to no water once established. Extremely drought adapted. Beautiful, free blooming shrub that has great promise.Somewhat open habit often with a twisting attitude. Lots of character. Thanks, Ian. High deer resistance.
Callistemon pallidus ‘Eleanor’
More than 25 years ago I raised some Callistemon from seed. This seedling with vivid magenta purple flowers has survived temperatures below 10ºF for all that time but requires a protected spot inland to thrive. Amazing performance at the Oregon Coast where the bright brushes may appear several times a year. To 6′ x 6′ and arching this willowy evergreen accepts light summer water and requires as much sun as possible. Best against a south facing wall in Portland. It may freeze back below about 12ºF, but recovery from the base is rapid. Virtually any soil. Moderate deer resistance. This seedling was planted at our then neighbor Eleanor’s house so it received that name. Photo credit: Evan Bean.

Famous for its hardiness to cold, this shrub eventually becomes very big with very large double, powerfully fragrant flowers. This fabulous Gardenia gains cold hardiness with age. Rich, moisture retentive soil that drains- see- LOTS OF COMPOST and regular summer water. That will not only speed growth and establishment it will encourage a constant supply of blooms from on average early July to September. To 4′ x 6′ in 7 years. Best in a protected location- especially from east winds. Full sun to full shade. Excellent with some overhead protection- tree branches , eaves, or a pergola. This slight protection provides the plant with less dramatic swings in temperatures which helps it harden off to cold. REGULAR irrigation is crucial for the first few years. Never let a Gardenia dry out entirely- no like. All the leaves from the interior out will turn yellow and drop. Not pretty. But a well grown shrub is gorgeous with large, deep green glossy foliage ensconcing the 3″ wide flowers. The fragrance will waft in warm summer conditions. Lovely. Excellent in containers – pay attention to irrigation and move the containerized Gardenia to an unheated garage or porch. Lucious and very tropical looking. Resprouts from the base if frozen.
Coast Polypody or creeping leather fern is an evergreen colony forming plant that is native from British Columbia south along the coast to even the Guadelupe Island off of Baja. It makes its home as an epiphyte trees, logs, rocks, the ground almost anywhere it finds adequate moisture and shade. During the summer it will take a surprising amount of dryness but we recommend light consistent irrigation for the best appearance and to spur multiplication. Fronds to 10″ long with rounded lobes. Excellent garden plant, grows very well in rich to average soil as well. Good year round appearance. A native fern that should be grown all the time. Great in winter containers- excellent winter appearance with little maintenance. Protect from hot sun. Highly deer resistant. A natural for the Oregon coast which is its native home. Oregon native plant.
Mountain white gum or just Mountain gum is a wonderful cold hardy Eucalypt that can achieve the largest proportions of any that we grow. In Portland specimens of 60′ occur and it presents as a large spreading tree with sickle shaped leaves of deep green and glossy. Very aromatic when crushed and excellent material for wreaths. In time it develops fantastic powder white bark. Fast growing in youth to 6′ a year in rich soil with regular irrigation. Once established it is very drought tolerant. In time it forms a large spreading crown on a majestic and easy to grow tree. Requires a large site. Eucalyptus are intolerant of all shade and should be hit from all sides by sunlight. Otherwise they will grow sparsely and lean towards the sun. White flowers occur in late winter and are more curious than showy. Does have some leaf drop- take note near patios. Cold hardy to 5ºF when established. Gains cold hardiness with age. Moderately deer resistant.
Arctostaphylos pumila ‘Small Leaf Form’
Immensely handsome dense rounded Manzanita that has smaller than average silver foliage and fantastic bark. Moderately fast growing shrub to 4′ tall x 5′ wide in 8 years. In late winter each branch tip is bedecked in clusters of small white flowers- they are born in profusion and expand from pink buds. Russet colored berries often follow and are consumed by wildlife. The black/mahogany glossy bark is beyond striking with the silver foliage. It splits, rolls up into ribbons, and exfoliates in late summer. In time it may be pruned to reveal trunks–for most of its youth they are hidden by dense almost formal looking foliage. Adaptable to many soils including clay soils- especially on slopes. Excellent long term landscape plant that looks great year round. Very good cold hardiness enduring 0ºF with no problem. Dig a hole 3x as big as the rootball in the pot to loosen the soil and allow the new roots to penetrate virgin soil. Water regularly through the first summer- then little to none in subsequent years. Combine with green leaved Arctos for great foliage contrast. Perfect on slopes, areas with intense reflected heat such as parking lot planter islands. Great urban shrub. Appreciates good air circulation.
Pittosporum tenuifolium ‘Garnettii’
One of the cold hardiest selections of this species native to New Zealand. This stunning evergreen shrub of unknown origin shines in the garden with round leaves edged in white with an interior of soft green. And these bright leaves are held on dramatic black stems. In spring small black to maroon flowers decorate the leaf axils. Moderately fast growing pyramidal shrub to 8′ tall x 4 wide in 7 years- and gradually larger. In winter the leaves become even more colorful taking on bright pink tints. Requires a somewhat protected location- avoid exposure to subfreezing winds directly. Best sited with protection from east winds. Full sun to high over head shade. Accepts regular summer water which will increase the rate of growth- but established plants are remarkably summer drought tolerant. Excellent cut foliage for arrangements. A luminous shrub that virtually glows in the landscape. Cold damage begins at about 10ºF- but spring recovery is rapid. Limited quantities.
Pittosporum tobira ‘Variegata’
An old shrub that deserves a new lease on life. Venerable old specimens are found throughout Portland proving its durability over time. The rounded evergreen leaves are edged in cream with an interior of soft sage green. In May/June masses of small white deliciously citrus-blossom scented flowers perfume a wide area. Not as dense or fast growing as the species- and prone to losing older leaves in colder than normal winters- so it can have an open appearance. Excellent evergreen specimen shrub for a hot location. A south or west facing wall is ideal and it can withstand the most withering afternoon heat. Slow growing to 6′ x 6′ in 10 years. Very drought adapted when established, but it will happily take regular summer water. The foliage is so fetching that it is often seen for sale as cut material in bouquets. It lasts for several weeks in a vase. Full sun to quite a bit of shade. Nice foundation shrub. Established shrubs are cold hardy to about 5ºF. Avoid exposure to strong subfreezing winds. Easy and pretty urban plant.
Chilean Myrtle is a very good looking dense evergreen shrub/tree in our climate. It requires a slightly protected location as it can be tender when young. Protect young plants from temperatures below 15ºF. With age and establishment it gains much, much more cold hardiness enduring 5ºF with just light leaf burn. The leaves are deep, dark green and rounded with a sharp tip. Almost formal looking. In protected gardens it can attain tree like status in about 8 years. Most often in our region its a shrub of about 12′. And perhaps the most impressive thing about this Chilean/Argentinian tree is the exfoliating orange to tan bark it achieves with age. In mid-summer masses of small white fragrant myrtle flowers with a central boss of exerted stamens smother the whole plant. These turn into sweetly edible if not a little mentholated black berries. They can be messy so locate away from paths, pavement. Birds almost always make off with the berries so that is helpful. Avoid direct exposure to subfreezing gorge winds. In gardens subject to that locate on a south or west facing wall. Very drought adapted when established, but consistent water and average soil will yield the best growth. Grows about 1′-3′ per year. Moderate deer resistance. Not a good plant for cold rural gardens. Tree size specimens are phenomenal and worth the effort to protect when young. Excellent performance at the Oregon coast.
This is one of the most popular shrubs in western Oregon of the last two decades. And rightfully so. This wild lilac sports excellent cold hardiness, prolific flowers, and glossy handsome evergreen foliage year round. A strong growing shrub that can literally explode in growth in rich soil but is much more restrained in poorer mediums. Remember this when planting it. It performs the best in average, un-amended soils in full sun with regular summer water for the first season to establish and then none in subsequent years. Sky blue flowers are profuse covering this dense shrub in a haze of color for 3-4 weeks in May to June. Later blooming that most other Ceanothus. This good looking shrub is so durable its made its way as highway verge mass plantings but it is just as stellar of a garden plant as well. Cold hardy to about 5ºF- it survived -5ºF in the southern Willamette Valley in 2013 by freezing to the snow line and then vigorously re-sprouting. Durable, dependable Ceanothus. Avoid the summer heat + water that it abhors- it leaves it open to root water molds that can do it in and fairly quickly. Excellent shrub for the beginning gardener. Loved by pollinators of all kinds and is virtually rolling in bees during its fabulous bloom. NOT DEER RESISTANT. Most likely a hybrid with C. thyrsiflorus which must be responsible for at least half of its make up. Found in Victoria, Canada- hence the name. Likely it is the old cultivar ‘Skylark’ that was re-named upon its survival there of a hideous winter. The old name was forgotten and the glee of survival and discovery led to the renaming. To be clear ‘Victoria’ and ‘Skylark’ are exactly the same thing. Very fast growing to on average 8′ x 8′. Excellent with all west coast natives. Blooms simultaneously with yellow Halimiums. A fantastic floral and cultural combination.
Canyon live oak is a vastly underused, beautiful evergreen native tree. Found from Lane county, Oregon south through California, slight parts of Nevada around Lake Tahoe and sporadically in Arizona and even New Mexico. This venerable tree is found on the steepest slopes of canyons and mountain ridges. In Oregon it represents the northern most native Live Oak or evergreen oak in North America. Leaves are glossy army green on the the top with a conspicuous furry gold underside. This is a rugged, tough tree that should be used in both gardens and as a street tree. In the Alameda neighborhood in Portland there is an ancient specimen to 60′ tall and wide with a large trunk. This heritage tree was reportedly brought to the city from southern Oregon via horse and wagon. Slow growing in youth it picks up speed exponentially several years after planting. To 40′ x 20′ in 30 years with a broad spreading crown. In the wild it often forms a gnarled multi-trunked rounded outline. Its very possible to train this tree to a single trunk/leader to extend the crown skyward. Extraordinarily cold hardy enduring temperatures slightly below 0ºF with no difficulty. The large acorns are born in a showy golden hued furry cups- and are produced profusely in banner years. Water to establish for the first season then none in subsequent years. Full sun. Beautiful, native Oak that we cherish at Xera. Oregon native plant.
Ceanothus thyrsiflorus ‘Rogue Sky’
A selection of Coast Blue Blossom or Ceanothus thyrsiflorus that we made very far inland from its natural range in SW Oregon. Typically relegated to the coastal strip we found this variety more than 35 miles inland. This improves cold hardiness. A rapidly growing shrub/tree to 16′ tall and 8′ wide in 7 years. Robin’s egg blue flowers smother the whole plant in May. Extremely drought tolerant this fast grower may be either used as a cool, evergreen, native, blue flowered tree or it may be pruned aggressively after blooming to limit the size- increase density create a screen or hedge. Loved by honey bees and all pollinators in general. No summer water once established. Excellent background tree that delights in bloom but fades to a green screen the rest of the year. Plant with other drought tolerant plants- Arctostaphylos, Cistus, etc. Grows 3′-4′ per year when established. The flowers are a soothing blue- which is hard to capture in photographs. The effect in bloom is a blue cloud. Takes partial shade and the worst soils. Oregon native plant.
Xera Plants Introduction
Aucuba japonica ‘Hosoba Hashifu’
A dazzling female selection of Japanese Aucuba with long, thin, tapered leaves of deep green randomly splashed with yellow spots. Dense and slow growing evergreen to 5′ x 5′ in 7 years. This selection will produce clusters of large red berries if a male is present. Very showy. Tiny brown/green flowers in spring are not conspicuous. Part shade to quite a bit of shade in average to enriched well drained soil. Established plants are incredibly drought tolerant and this striking shrub adds light and texture to dry shade areas. It will take full sun with regular irrigation and the leaves will be not as dark lustrous green. A very handsome shrub year round with great cold hardiness. Regular water through the first season to establish. Then light water. Long lived, easy to grow shrub whose dense habit does not require pruning.
Melianthus major ‘Purple Haze’
Nice selection of Honey Bush that shares tints of purple predominantly when new leaves are unfurling. The enormous blue/lavender serrated leaves are amazing. Lower growing than either the species or ‘Antonow’s Blue’. To 4′ tall (usually shorter) by at least 6′ wide. Red flowers are produced on the black scape that can follow mild winters. Technically a subshrub as it can freeze to the ground and fully recover from the root in a single season. IF it has been well established in its first season. For that reason we only sell Melianthus in 2 gallon sizes. A larger plant establishes faster and has more mass going into winter. Plant in a protected location- against a wall or with light overstory protection. Mulch for the first winter. Freezes to the ground at prolonged temperatures below about 20ºF. Re-sprouts in mid-late spring. Water and fertilize to speed the recovery. South Africa.
For several reasons this is a fantastic Helianthemum (Sunrose). Felted green/gray foliage is handsome as a backdrop to the masses of fully double pink flowers that appear for weeks. The single forms of Sunrose have flowers that last just one day but this double flowered form has flowers that individually last for days. It significantly lengthens the bloom time on this charming low plant. Blooms appear from mid May to July. To 10″ tall and spreading to an area 2′ x 2′ in several years. Full sun and well drained soil of rich fertility. Beautiful small scale groundcover for banks, drier borders, rock gardens. Its best to cut Helianthemums back hard when blooming has ended. Remove the blooming stems and part of the current seasons growth. In return you achieve a dense compact plant that will yield more flowers the following year. For pink-o-philes this is a must have plant and one of our favorites at Xera. Light summer water. Some deer resistance. Not available in 2023
Grevillea x gaudichaudii
Impressive ground cover Grevillea that can be difficult to locate. To less than one foot tall it spreads out laterally easily 8′ wide in 7 years. The distinctly oak shaped leaves on this shrub emerge deep red before settling to green. All the while it is producing red upward facing “toothbrush” shaped flowers. These appear from February to August primarily but can pop off occasionally year round. All together it forms an amazing ground cover shrub that features fantastic foliage and flowers in a bold tapestry display. Cold hardy to a bit less than 10ºF- it appreciates successively colder frosts to harden off for its ultimate frost resistance. Full sun to part shade in average, well drained soil. Light summer water increases the growth rate- and it can zoom once established. Avoid crowding from other plants- it seems to require good air circulation. Excellent performance on gravel mulch. Large rock garden plant or hot slope cover. Protect young plants from temperatures below 15ºF- it can burn the foliage. Hardiness increases with establishment. The very short trunk emerging from the ground can be surprisingly stout- several inches in diameter. Cover with frost cloth- held down for wind protection during extreme arctic events. Drought adapted when established. A protected location. One of the coolest shrubs we can grow. A naturally occurring hybrid from the Blue Mountains. Excellent around and over boulders which add radiant heat during extreme cold. Should only be attempted in the mildest gardens.
Scorpion weed is a beautiful native perennial found on rocky slopes/ hillsides/road cuts throughout California and western Oregon. Handsome corrugated trifoliate leaves are silver and have a pointed tip. In May-July curled flower inflorescences arise unfurling as they bloom to reveal rows of mauve/blue flowers. To 2′ tall in bloom it forms a handsome dome of evergreen foliage to 14″ across. The leaves are the most striking and conspicuous feature of this plant. Pollinators adore the flowers and its especially important for native bees. Full sun to very light shade, average, well drained soil. Light summer water. Excellent in the front of borders. Wonderful bold contrast with other fine leaved silver beauties- it even shines with lavender. As you hike throughout the mountainous parts west of the Cascade Crest the incredibly handsome leaves are sure to catch your eye. Easy to grow and perfectly climate adapted. Oregon native plant.
Grevillea juniperina ‘Firewoman’
About 15 years ago we planted this tiny seedling at the top of our propagation hill behind our wholesale nursery in Sherwood. After all those years and two trips down to 5ºF, numerous ice, snow, wind events it has remained completely happy and unblemished. This is closer to the species in form. To 4′ tall x 6′ wide in 5 years. Very prickly needles pose as the leaves forming a very formidable shrub. From January to July flaming red/orange flowers are curly and lick the tips of the stems like flames. And LOVED by hummers. Full sun to part shade, the very poorest, most well drained soil with no summer water once established. Takes clay soils on slopes. Completely drought adapted and it likes it that way. Great deer resistance. Long season of bloom on a charming architectural evergreen shrub. Excellent companion shrub for Arctostaphylos ( they both bloom in winter and attract hummers) as well as other drought adapted plants such as Italian Cypress and Arbutus. Our plant lives in what is termed ‘gravel reject’ which is the tailings from the gravel pit near by. It is 50% gravel and 50% fine soil- and is fairly challenging as far as summer drought goes. This plant has thrived. In richer soil expect faster growth. We do not give our stock plant supplemental water ever. Tough plant.
Xera Plants Introduction
Dianthus petraeus ssp. noeanus
Adorbs rock garden Dianthus with fine deep green foliage forming rounded mounds. In late spring to summer 8″ stem support feathery intensely fragrant white flowers. They come in a mass and are fragrant of cloves many feet away. It makes a great cut flower for small arrangements. To 8″ across for full sun and sharp drainage and light consistent summer water. Rock gardens, troughs, slopes. Easy to grow rock garden variety.
Baby’s Tears is a useful and surprisingly hardy small scale ground cover. Famous for its role in terrariums its surprisingly hardy to cold as well. Tiny leaves overlap in a perfectly flat deep green ground cover. Part shade to shade but not terrible dry shade or compacted soils. Spreads to several feet wide in several seasons. Rich, moisture retentive soil that drains is ideal. Mist or water once a week to increase humidity which it very much appreciates. Freezes to nothing below 15ºF- resprouts from bits of root vigorously in spring. Do not try to cover the whole planet with this diminuitive plant. Instead isolate it to cool pools of green several feet wide. Excellent in containers or as an easy houseplant.
Iris x pacifica ‘Big Wheel’
Astonishing flower color is one reason to love this large flowered Pacifica hybrid. Orange/coral/pink all morphed into one hue with a central zone of deep purple near the center. To 1′ tall and forming spreading clumps of evergreen foliage. Blooms April-June. The large flowers are showy from quite a distance. Part shade is ideal but endures full sun and tolerates total shade. Water regularly through the first summer to establish- the clump should increase by twice its size then none in subsequent years. Resents disturbance best left where it is to live. Great deer resistance. A very unusual color for a PCI.
Osmanthus heterophyllus ‘Kaori Hime’
What a sweet little version of Holly Tea Olive. Leaves are tiny compared to the species and the whole plant is a diminuitive version of the that plant. To just 4′ x 4′ in 10 years it eventually gets progressively larger. An extremely floriferous form that condenses hundreds of small white fragrant flowers along the stems in October to December. Slow to finish in a container because of its size- be patient. Grows about 4″ per year. Foundations, rock gardens, hedges, specimen. Great cold hardiness for a broad leaved evergreen. Drought adapted when established otherwise it tolerates regular irrigation which will eventually speed growth. Cute. Really, freaking cute ancient cultivar from Japan. Rare plant that is slow to increase. Limited quantities.
Camellia x williamsii ‘Brigadoon’
HUGE. The flowers on this Camellia are HUGE. Semi-double pink flowers are up to 5″ across. Don’t diss pink. No other flower does pink quite like Camellias. ‘Brigadoon’ is a spectacular hybrid that blooms for the last month of winter and the first two months of spring. Clean, glossy, deep green foliage is handsome at all times on a dense growing shrub to 8′ x 4′ in 6 years. Grows about 1′ per year. Full sun to part shade to quite a bit of overhead shade so long as it isn’t oppressive. Huge amounts of buds open to these voluptuous blossom. Excellent cold hardiness enduring temperatures just right below 0ºF with no damage. Excellent resistance to subfreezing gorge wind- it would be a great windbreak to stop that arctic blast. Flowers fall completely off of the shrub never clinging and turning brown. Easy, long lived, climate adapted shrub.
Iris x pacifica ‘Rio Dorado’
Yellow is a special color for Pacific Coast Iris and this selection does a great job at producing profuse large luminous yellow flowers for an extended period. To 14″ tall and forming spreading clumps. The vivid flowers are showy from a distance and resonate with the candy-like colors of other Pacific Iris. Mix with ‘Blue Moment’ for a classic blue and yellow combination. This Iris also blooms simultaneously with the clouds of blue flowers of Ceanothus. And they appreciate the same cultural conditions- a late spring vignette that gets by on no summer water! Evergreen. Not fussy about soil. Water consistently through the first summer to establish (established Iris will double their clump size in the first summer). Then only what falls from the sky in subsequent years. Heavy bloomer in April-June. High deer resistance.
Anthyllis vulneraria var. coccinea
Kidney Vetch is a playful, short-lived perennial with shocking red flowers that come in clusters much like clover. Low, spreading plant that hugs the ground, all the better to see the piercing red flowers on this form. Seeds prolifically, and the seedlings are both easy to identify as well as move or dispatch. To 3″ tall by 18″ wide, when very happy. Loved by pollinators. Forms a vivid patch of color in the most unlikely places. Seeds germinate in autumn and bloom commences in spring. Excellent little nitrogen-fixing temporary plant for new gardens. Enriches soil in a wonderful way. Light to little summer water. Mediterranean.
Osmanthus heterophyllus ‘Akebono’
An exceptional Tea Olive that we love. New growth emerges pink before changing to lacquer white and finally deep green. This period of transition lasts for months and is far showier than the small white flowers that cluster at the leaf axils in autumn. They do, however, emit a sweet perfume that is detectable for many yards. Great cold hardiness for a broad leaved evergreen enduring temps below 0ºF with no harm. Tolerates subfreezing wind and would be a fantastic and showy hedge to block the east wind. To 7′ tall in 7′ years eventually reaching small tree size. Full sun to part shade in average to enriched soil where there is never standing water in summer. Tolerates clay soils on slopes and it is best with about 3 deep soaks per summer once well established. Mulch when planting. Avoid reflected heat. Moderately deer resistant. Blooms on old wood. Prune if needed AFTER blooming has ended. Naturally dense habit. As the shrub matures the leaves which are mildly prickly in youth change to smooth edged entire leaves. Pretty, tough, dynamic shrub. Japan.
Veronica peduncularis ‘Georgia Blue’
Its been around for a long time and its an introduction that has stood the test of time. This low mounding evergreen perennial is beyond delightful when it alights in masses of deep blue flowers from late February to late April. Each simple blue flower has a small white eye but the effect from a distance is a pool of blue. To 8″ tall and forming large 2′ x 2′ wide patches in full sun in rich to average well drained soil. It excels on slopes and in rock gardens. The new growth that follows is tinted mahogany before become strong glossy green. Cut back by 1/3rd after blooming to create a much denser and ultimately more floriferous plant. Light, consistent summer water. Excellent bold backdrop to early and mid blooming bulbs. We suggest large white Crocus vernus followed by Narcissus ‘Blushing Lady’. Very easy to grow. Long lived for a speedwell.
Epimedium x ‘Supernova’
Something about the clean lines of the hot yellow flowers topped with a symmetrical bright red cap recalls a miniature explosion in space. Wiry stems to 14″ support clouds of this starry flowers from late March for and extended period well into summer. New growth is mottled with maroon over an initial hue of amber before settling to soft glossy green. All together this is a great performer for part shade to shade in rich to average well drained soil. Regular summer water not only refreshes these tough shade plants it will spur them to increase. The rewards often are not apparent until the following spring. Cut away the evergreen foliage in late winter to reveal the new years flower as well as highlight the pretty new growth. Good deer resistance. Spreads moderately fast to form a clump 20″ wide in 5 years. Nice cut flower as well. Very easy to grow.
Xera Plants Introduction
Pinus ponderosa var. benthamiana
Pacific ponderosa pine is a lovely tree native west of the Cascades from about the Portland area (with some outliers farther north) south to northern California. Our form is from locally collected seed. Slow growing in youth this pine picks up speed in its teens and grows almost exponentially from there. Pacific ponderosa pine is known for it tall straight crowns of lush green needles in clumps of three. This tree is excellently adapted to our winter wet/summer dry climate and even small trees can endure the very longest, driest, hottest summers with no visible stress. Its adaptable to all types of soil – not fussy and is even found in the most well drained stranded flood cobbles of major rivers. To 125′ in time with ulitimate height of close to 200′ in great age – expect a 3′ tall tree to be about 15′ tall in 10 years. Full sun- not very shade tolerant and when planting with other trees anticipate at least a 25′ wide crown in the future. Needles can drop profusely in September which is a bit of a mess. Take note of this. Underplant with other drought adapted natives. Water to establish for the first summer then none in subsequent years. A regal pine that is among the tallest in the world. Oregon native plant.
Ceanothus thyrsiflorus var. griseus ‘Kurt Zadnick’
What a surprise this very dark, dark, dark blue flowered Ceanothus has turned out to have excellent cold hardiness. In our climate it is a low and spreading evergreen shrub with glossy leaves. To 3′ tall by 6′ wide in 6 years. In April/May a profuse display of the darkest cobalt blue flowers mass over the whole plant. Its so dark that it can seem like shadows over the plant but closer inspection reveals the intensity of the color blue. Full sun to light shade in average soil. Tolerates clay soil as well as withering summer drought. Prune if needed lightly after blooming has ended. This is a great drought tolerant, heat tolerant low shrub for hell strips. No summer water please. Well scaled for hell strips, low massing or a higher ground cover for hillsides. Fast growing to its ultimate size.
Grevillea juniperina ‘Lava Cascade’
Low ground cover form of the Juniper Grevillea. Spreading to 6′ wide it rises to just 2′ when happy. Most of the time it is much lower. This selection is the most commonly seen orange form of this species. Spidery orange/red flaming flowers appear in clusters at the branch tips. The most likely bloom period is February-June- but older plants pump out sporadic flowers year round. Excellent on slopes- especially warm south facing slopes in a protected location. Surprisingly cold hardy enduring temperatures down to about 8ºF with no damage. Avoid subfreezing wind as well as boggy conditions and crowding from other plants. It likes to dry out in winter, and loathes wet plants laying on it. Extremely drought adapted requiring no supplemental water after a year or two. Highly deer resistant. Excellent evergreen- but prickily shrub for Hell strips. Loved by hummingbirds. We have since introduced G. j. ‘Xera Ember’ which is a more compact shrub 2′ x 4′ and has more deeply hued (bordering on red) flowers for a longer period. Gains hardiness with age. Pictured here with ‘Molonglo’.
Grevillea x ‘Constance’
This is an important hybrid that is among the best known in the United States of G. victorae x G. juniperina. A wiry rounded shrub with thin twisted green leaves that are rolled at the margins. Throughout the year a constant procession of orange/red flowers decks the whole frame. Loved by hummingbirds. To 7′ x 7′ in 7 years in average, well drained soil in full sun with little water once established. Not the hardiest Grevillea and has been superseded by cold hardier and superior varieties- such as ‘Neil Bell’. It is, however, an excellent evergreen shrub for the milder coastal regions. In Portland it is relegated to the warmest urban areas in protected locations. Easy fast shrub that you should protect from subfreezing wind inland. There are enormous specimens on the northern Oregon coast that adore that climate and it is naturally adapted to sandy soils. High deer resistance. Loved by hummingbirds. Prune to contain and maintain a compact habit. Hardy to about 13ºF- or slightly less hardy than ‘Canberra Gem’. Very floriferous.
Grevillea australis var. prostrate
Interesting plant for the collector. This is a low and mounding form of the hardiest Grevillea species. The tiny leaves are pointed, not rolled as in the species and they have a uniform tan green hue. In spring- after several years in the ground tiny flossy white flowers swarm the foliage from every leaf axil. They emit a penetrating honey perfume for weeks. VERY VERY slow growing to just 8″ tall and barely 2′ wide after 7 years. Full sun- no shade at all and average to poor well drained soil. It does just fine in native soil that has not been amended and its ultimate preference is for loam. Excellent small evergreen shrub for rock gardens, small spaces. More of a collectors plant. Useful on steep hillsides. Very hardy to cold enduring 5ºF with no issues. Little to no summer water. Moderate deer resistance. Slow. Tasmania, SE Australian Alps. In the wild it cozies up to boulders to absorb radiant heat. This could be repeated easily in a garden. Rare. Limited quantities. This is a form selected and named in New Zealand.
Surprisingly cold hardy and wonderful Grevillea that is threatened in the wild. Crinkly, prickily, finely divided leaves (bipinnapartite) create a haze of a frame to 5′ x 6′ in 6 years. This “cage” of foliage is intermittently decorated with soft purple flowers from spring to early autumn. These are tipped with a bright green style that is released in bloom. The flowers are often described as toothbrush like. Full sun to very light shade in average soil. Light summer water speeds growth but that is the only reason it is necessary. A protected location. Hardy to about 10ºF- and suffering no damage in the wild winter of 2016/17. Protect from subfreezing wind. Easy to grow with neglect and good siting. Same hardiness to cold as ‘Canberra Gem’. Give it room as it will steadily and methodically increase before you know it. Moderate deer resistance. AKA Carrington Falls Grevillea. Avoid fertilizers. If it never bloomed this shrub is fantastic for texture alone. Not for cold gardens- best with some urban protection. Very limited quantities.

Rhaphiolepis umbellata ‘Blueberry Muffin’
Excellent release from the JC Raulston Arboretum in Raliegh, NC. This dense and rounded shrub is useful for its size- 3′ x 3′ in 7 years- or longer. But it has many other fine points. The leaves are thinner than normal with this species which is native to Japan. It is very very black spot resistant and the leathery glossy leaves turn from olive green/gray in summer to amazing stains of maroon and purple with cooler temperatures. New growth is light beige and coated in furry indumentum before becoming glossy. A fascinating and beautiful display. White flowers appear in May and are followed by fairly showy blue berries. Extremely drought tolerant and tolerant of high heat. Excellent on south facing walls or exposed urban situations with reflected heat. Handsome at all times and very easy to grow. Grows about 4″ per year. Nice measured growth that forms a rounded upright shrub. Excellent companion for other drought adapted shrubs-landscapes. It also accepts regular irrigation in summer- a useful adaptation for an already useful shrub. Full sun to part shade.
Achillea millefolium ‘Calistoga’
A fine form of our native Yarrow that has leaves that are a striking gray with pure, clean white flowers. A great combination. Spreads to form a low wide plant that is evergreen (gray). The flat clusters of flowers appear continuously from May to frost. More consistently if you remove spent flowers. The umbels, unusual for the daisy family, are loved by butterflies. Well, actually all pollinators. They are given a flat landing pad and tons of flowers- what more could you want. Excellent for low care areas where this romping perennial will happily out compete weeds and hold ground with very light amounts of water. Full sun and well drained soil. its best to double dig the soil to incorporate oxygen and de-compact the soil. Does not like compacted soil. Light but consistent summer water speeds growth and vigor. Otherwise very drought tolerant. Excellent on slopes. To 20″ tall in bloom on a low spreading foliage plant to 2′ wide or wider. High deer resistance. Great cut flower. Mix with other low water plants. Pretty with other colors of yarrow. Oregon native plant.
Very good evergreen climbing Hydrangea that is a tough and reliable vine for shady walls. Large slightly indented leaves are glossy green year round. Self clinging vine that will adhere to virtually any surface- not for the walls of houses or porches- better on fences, rock walls and even as a ground cover. In June large white buds explode into a doily of 6″ wide white flowers. Blooms 2-3 years after planting. To 15′ tall and as wide. Part shade to shade- regular water in full sun. Rich, well drained soil. Excellent cold hardiness to 0ºF. Gains speed as it ages. Avoid blasting hot locations. Woodlands are ideal.
Arctostaphylos columbiana ‘Parkdale East’
This form of our native Hairy Manzanita was found quite far east of the Cascade crest and offers greater hardiness to cold. Unfortunately, it has the same characteristics of the species- it is unpredictable. To 4′ x 7′ with sage gray leaves and white to pink-tinted flowers in spring. Very well-drained soils in an open position with NO summer water when established. Dramatic smooth mahogany bark is an outstanding feature. This is the variety that is best suited to life in the Columbia River Gorge and possibly eastern Oregon in sheltered sites. It should easily tolerate -15ºF. Best with total neglect and full sun. Russet berries follow the flowers into summer and autumn- always consumed by wildlife. Very limited quantities. This form has been successful in cold gardens east of the mountains where all other California varieties failed. Nice looking shrub. Oregon native plant.
Xera Plants Introduction
Cupressus (Hesperocypress) macrocarpa ‘Citriodora’
Fantastic form of the incredibly tough Monterey Cypress. Foliage on this fast growing large evergreen tree is brilliantly hued in chartreuse/gold and acid green. Pinch the foliage and the fragrance of lemons is released. Fast growing tree for poor to average well drained soil. Avoid overly rich soils- which causes rank, unsteady growth. Average un-amended native soils are best. Light summer water to initiate growth and then completely drought tolerant. To 35′ tall x 25′ wide in 15 years. In time it develops a really cool flat spreading crown that this species is so famous for. Great drought and cold tolerance at our nursery. Give it amble room, full all day sun and not much else. Cold hardy to 0ºF. Long lived tree. This species has been placed in the genus Hesperocypress.
Alexandrian Laurel is the common name for this evergreen shrub that is a member of the lily family. Common as a cut foliage component in bouquets- it lasts for weeks in a vase. Arching glossy evergreen plant with handsome foliage year round. To 3′ x 5′ wide forming expanding clumps. Tiny flowers transform to showy orange/ red fruits which hold for months on the plant. Part shade to full shade- including the worst dry shade. Regular summer water or very little when established. Moderately slow growing- about 2 new stems per year. Rich to average well drained soil. Great plant for dust dry entryways or under stairwells. Very cold hardy and long lived. Moderate deer resistance.
Cupressus glabra ‘Sulphurea’
Remarkable form of the hardy Arizona Cypress. This variety has foliage frosted in chartreuse/cream with interior foliage closer to sea green. A great affect. To 15′ tall but only 4′ wide this is a decidedly fastigiate form of this species. Fast growing tree for screens, specimen. Poor to average soil- avoid rich soil- this causes Cypress to grow to fat and fast in our climate- they get rank and rocky. So plant in average to poor soil with light irrigation until you see appreciable new growth and then none- ever. This produces a more measured growth rate and a sturdier plant. Full sun- from ALL directions- no shade at all. Open exposed sites are best. Very pretty plant that adores our climate. Cold hardy below 0ºF. Rare tree and quantities are limited. Completely drought tolerant.
Parahebe cattaractae ‘Delight’
Cute little subshrub that is for the most part evergreen in our climate. Slightly toothed glossy deep green foliage is demure but sets a great stage for masses of violet blue small flowers with a more distinct red eye. Blooms continuously from Spring to late summer. To 8″ tall and about 2′ across for rich, well drained soil in full sun to light shade. Cute understory for Roses, mixes well in the front of a border, on sunny hillsides. Creates a haze of violet blue rather than a carpet. Cut back hard after blooming for an emergence of new handsome foliage for autumn/winter. Easy to grow long blooming plant.
Helleborus x ‘Blue Diamond’ Winter Jewels ®
Well, blue may be a stretch but this difficult to photograph hue at least attains hints of the color. More aptly its a luminous pewter shade that seems to reflect light in a metallic way. Strong growing perennial for part shade to shade in rich, well composted soils. Regular summer water- though it takes dry conditions in the shade. In extreme drought the leaves will simply lie on the ground- rising up almost immediately with water. Blooms appear from late January and are effective until April. To 2′ tall and as wide in several years. Excellent in combination with the yellow flowered series ‘Golden Sunrise’. Highly deer resistant and long lived. Remove self sown seedlings which will unlikely come true to the parent. A special color.
Curious low, evergreen, winter blooming shrub that erupts in 3″ long pale, ghost green flowers from January to March. To just 2′ tall and spreading twice as wide its large rubbery, dark evergreen leaves are a great backdrop to the flowers. Just as nice the leaf petioles are a dramatic madder red. Rich, well drained soil with regular summer moisture. Part shade to high overhead shade. Excellent combined with Hellebores, Cardamine, Cyclamen coum- which all desire the same cultural requirements. Strongly horizontal habit. Blooms on wood from the previous year prune (very lightly) if needed after flowering has ended. Moderate deer resistance. AKA Laurel Leaf Currant. Wonderful on shady hillsides where it lights the winter months.
This little gray leaved evergreen shrublet becomes a fire of true red flowers for 4-6 weeks in mid to late spring. To 10″ tall and spreading to several feed wide in rich, well drained soil with light but consistent summer water. Better in soil that has been enriched with a bit of compost and light organic fertilizer. Each flower lasts just one day but they come in such profusion that the display is continuous for weeks. Excellent slope cover- rooting where stems touch the ground- ideal erosion control. Cut back hard after flowering has ended. Cut approximately 1/3 of the plant away and new fresh foliage will emerge creating a solid mound of foliage. Very brilliant Sunrose that we love.
Arctostaphylos pajaroensis ‘Lester Rowntree’
Virtually the same as ‘Warren Roberts’ it is completely interchangeable with that cultivar. Why do we grow ‘Lester’? Aside from having amazing blue foliage and clusters of deep pink flowers from January to March we LOVE Lester Rowntree. She was an amazing, intrepid self-taught botanist who roamed California in the 1930’s in her simple pickup truck camping and botanizing throughout that state. Her incredible book ‘Hardy Californians’ is a must read for any gardener on the west coast. And its not just about plants- Check it out. This shrub is large in time to about 4′ tall by 8′ wide. The pink flowers born on the blue foliage is a sublime combination. Following bloom new spring growth is a fantastic red/ orange before settling to blue. Bark is a smooth mahogany with time and the trunks are sinuous and winding. This is an excellent shrub in our climate. Once established it requires absolutely no supplemental water- ever. Sailing through temps in the 100’s and bone dry with NO visible signs of stress. Our kind of shrub. It is cold hardy and completely climate adapted. Hell strips, dry borders, informal shrubberies. Mix with Ceanothus, Grevilleas, Halimiums. Very pretty year round.
One of the world’s most fascinating shrubs. Polymorpha in this case specifically refers to the leaves which are a different, form, shape, and texture on each individual plant. Very unusual for a hardy shrub. In early summer each form produces upright 5″ tall trusses of ivory/white flowers that are sweetly fragrant- blooms appear for 2 to 3 weeks. An evergreen shrub- usually of fine texture, that grows moderately fast to 3′-6′ in 5 years. In time the shrub will be larger. Full sun and light summer water, avoid sites with standing water in winter. Excellent on slopes. Native to the highest elevations of Tasmania. Its been cold hardy to about 5ºF. In cold gardens I would err on the side of protected. Does not tolerate shade of any kind. Full, all day sun. Light summer water. We have chosen three clones that we think are particularly handsome and we will be trialing those plants. Until then seedlings all with variable foliage are what we offer. Some have a very compact congested habit while others have stretched out and appear to be ultimately larger plants. Excellent as cut foliage as well as cut flowers. A large shrub in full bloom is a beautiful, sophisticated, party of curly ivory flowers. Fantastic. Might be deer resistant. Very good performance at the Oregon coast. Very rare shrub. Proteaceaous- avoid compost and fertilizers. Mulch with bark/ wood chips. Best as a single specimen. Most applicable common name ‘Variable leaf Lomatia’. That about covers it.
Osmanthus heterophyllus ‘Variegatus’
Excellent cold hardy, drought tolerant shrub that reaches tree like proportions with great age. The pretty variegation presents as prickly leaves outlined in white. With age/maturity the leaves lose their prickles and become smooth and entire. The variegation on this plant is incredibly stable. I have yet to see a reversion of any consequence. Ancient specimens that are now 20′ trees can be found in old, old gardens. Its obviously been grown in this climate for eons. Very, very cold hardy evergreen that is not only hardy below 0ºF it makes a great hedge even near the Gorge where it endures subfreezing wind with no ill effects. Tolerates regular irrigation which increases the rate of growth- on average about 2′-3′ per year can be expected. 8′ x 6′ in 7 years is typical. Full sun to shade. Avoid permanently boggy soils- otherwise very adaptable- including heavy dry summertime clay. In October-December tiny fragrant white flowers crowd the stems. Moderate deer resistance. Long lived.
Unless you look REALLY REALLY closely you would never even think this was a Pittosporum, let alone even in that family. But life was tough in alpine New Zealand and this baby would have none of the grazing by huge Moa Birds. So the twiggy, zig zaggy stems evolved (the official term is divarication). The tiny, tiny leaves are serrated if you look closely (you might even take out glass to amplify the details). Tiny white flowers line the stem and mostly go unnoticed in spring. What it does provide is a very architectural compact shrub with stunning black stems in winter that change to ashy grey in summer. Perfectly hardy to cold down to below 5ºF. Full sun and average to enriched soil with little summer water once established. Groovy, somewhat rare shrub for excellent effects. To 6′ x 3′ in 8 years. Moderate deer resistance. Great structural shrub for containers.
Viola odorata (Parma) ‘Alba Plena’
This cool cultivar of Parma violet can be difficult to stumble upon. We love the plush double white flowers that sends its sweet perfume on the breeze in late winter to mid-spring. Parma violets are basically the Sicilian version of the common sweet violet (Viola odorata). They are not nearly as cold hardy or pernicious as the species and they tend to have much larger more opulent and fragrant flowers. Also, their leaves are distinctively glossy as opposed to matte. This little sweetie forms spreading patches and the long stems are a bit weak for the large double white flowers- they tend to bend. Excellent for small bouquets that you can sniff and sniff. In the garden they need a sheltered position away from the freeze and thaw and harsh conditions in the open. Instead coset them under large shrubs and among ephemeral early perennials such as Anemones, and small bulbs like species Crocus. Part shade- they bloom best with a bit of sun. Regular summer water encourages them to spread. This form seldom sets seed- I don’t think I’ve ever seen seed in fact. Pity. Rare plant.
Illicium floridanum ‘Pink Stars’
This form of the aromatic Florida Anise shrub which is native to the SE United states bears showy 2″, spidery star-like flowers of the palest pink. The entire large shrub displays these outward facing flowers in March to April and again in September to October. The flowers have an odd scent up close- mothballs or fish- but in our climate it blooms when it is cool and the odor does not carry. More importantly its a handsome broadleaf evergreen shrub with sharply pointed long leaves that have a sweet delicious anise flavor when bruised or brushed. Upright and then spreading shrub to 8′ x 6′ in 7 years. Best with light shade to shade for the deepest green foliage. Tolerates full sun as long as there is not the reflected heat of a wall. Flowers are showy from quite a distance. Excellent among rhododendrons, as an understory shrub for interest, joy. Very hardy to cold, enduring subzero readings with no damage. Nice hedge. Moderate deer resistance. Rare, cultivar. Light consistent summer moisture. Established plants are summer drought tolerant. Easy.
Roughbark Manzanita is a little known species of Arctostaphylos from the central California coast that has turned out to be a great garden plant. Nearly round leaves cling to the winding upward pointing stems. In a short amount of time it forms a rounded, spreading shrub to 3′ tall by 5′ wide (5 years). Late winter bring profuse blush pink urn shaped flowers- followed by clusters of large tight blushed red drupes. Full sun and average, well drained soil with good air circulation. No summer water at all when established. This not only gives it the neglect it adores it increases hardiness to cold in winter. Avoid, exposure to subfreezing winds… not a Manzanita for Gresham or Troutdale but in milder parts a great landscape shrub. Group with other drought adapted shrubs. Handsome smaller scale shrub for hot sunny sites. Develops shredded cinnamon red bark with time. Performs very well in containers. Photo credit below: Lance Wright.
Camellia sasanqua ‘Hugh Evans’
Rare, obscure, insanely heavy blooming fall and winter blooming Camellia sasanqua. Individual flowers are not formal or stiff, instead the the petals are separated, loose and vivid pink. They appear en masse from October to January and decorate the lithe arching stems in pretty cascades of flowers. Blooms are exceptionally cold tolerant for a sasanqua enduring temperatures into the low 20’s and still remaining fresh. No bother though as a parade of buds exists to replace spoiled blooms. Full sun to quite a bit of shade- without the expense of blooming. Fast growing, vigorous open shrub that takes well to pruning in spring to encourage density- build blooming wood. Rich, to average well drained soil with light consistent summer water. A very wild and informal appearing Camellia and we love it. Glossy deep green foliage. To 5′ x 7′ and arching. Light flower fragrance.
Iris unguicularis ‘Walter Butt’
Not a very enchanting cultivar name but a useful and distinct flower color variant of Algerian Iris. This winter blooming species produces large pale lilac/ivory flowers from November-sporadically until March. The 4″ flowers are nestled in the grassy evergreen foliage but are a light enough color to read from quite a distance. This for is perhaps best planted with the species to produces contrasting flower colors for more depth. To 1′ tall and twice as wide in several years. Full sun to very light shade in well drained soil of average fertility. Not quite as cold hardy as the species but it has to get pretty damn cold (below 5ºF) for damage to occur and that just never happens. Long lived perennial. High deer resistance. Low summer water requirements.
Camellia x williamsii ‘Waterlily’
Extraordinary hybrid that combines all the great attributes of a Camellia with larger, more dramatic flowers and more of them. It also possesses excellent cold hardiness as well as garden adaptation. Large growing glossy evergreen shrub with fetching deep green leaves. In late January to early March- and often longer than that depending on the weather 5″ flat fully formal double clear pink flowers are stunning. You really have to see them up close to get a handle on the size and perfection of each flower. Upright growing shrub to 9′ tall by 7′ wide in 10 years. Full sun to quite a bit of shade in well drained soil that retains moisture. Light consistent summer moisture aids establishment and also increases the amount of flowers the following season. Established plants can endure quite a bit of drought. Exceptional cold hardiness, slightly below 0ºF. . Flowers shed cleanly- they shatter without clinging and discoloring. Excellent candidate for a large espalier. Exquisite large shrub.
Camellia x williamsii ‘Buttermint’
Unusual, profuse and a great color for a Camellia, ‘Buttermint’ produces fully double, but small flowers that deck all the stems for months in mid-winter to spring.The flower color is elusive with warm tones of light yellow on the interior fading to a bone color farther out on the petals. Moderately fast growing evergreen shrub to 6′ tall and 4′ wide in full sun- but not reflected heat, part shade to quite a bit of shade. Regular, consistent summer irrigation for the first few years to establish. Older plants can get by without summer irrigation- but bud set and flowering is improved with such. The flower color is aptly described by its name. Pale yellow to buff to off white as they unfurl. Flowers do not turn brown and cling when spent instead they drop cleanly so in bloom there is a uniform fresh appearance. Long lived shrub that grows about 1′ a year when young. Give it room in time. Exquisite winter blooming companion for Hellebores, Grevilleas, Iris lazica, Iris unguicularis. Small glossy deep green foliage is fetching year round. Sets many, many flower buds in autumn.
Eschscholzia californica ‘Cream’
A very favorite annual or short lived perennial. This excellent California poppy sports ivory to cream large flowers for an extended period in summer. Fine blue foliage is wonderful with the softly colored flowers. Blooms from April to August if you give it a little water- but never soggy. Full sun to the very lightest shade in average to enriched, well drained soil. Un irrigated plants will bloom for a shorter period and set seed. The seed comes true about 90% of the time. Cull orange or other colors that don’t please you. It may become a short lived perennial if treated well. New plants germinate en masse with the first autumn rains. Don’t be afraid to thin your patch a bit then. Rough areas, along gravel paths. Easy to grow. Containers, Hellstrips. Etc. High deer resistance. Oregon native plant.
Trachelospermum asiaticum ‘Chirofu Chirimen’
Cool little Asian Star Jasmine with tiny variegated leaves that forms dense mounds as a ground cover or in time it can reach up as a cute and not strangling vine. Each leaf is margined and splashed with white. New growth has distinct pink tints for a distinct multicolor effect. Forms a fine textured plant but as a small scale ground cover it will block weeds. To 1′ tall x 30″ wide as a ground cover. To 8′ tall or higher as a self clinging vine in wind free places. Rich, well drained soil with regular summer water. Definitely double dig the soil before planting to incorporate oxygen as well as assist in absorption of water. Add organic fertilizer as well. Trachelospermums appreciate good drainage and regular summer irrigation to do their best. Otherwise drought tolerant but slow growing. Nice on fences or screens or up the trunk of a Trachycarpus (Windmill Palm). Good deer resistance. Evergreen.
Halimium x pauanum
Nice, upright golden rockrose with felted gray foliage and masses of flowers from May-July. To 3′ x 3′ in full sun and well drained soil of average fertility. Little to no summer water once established. The simple, silky, egg yolk yellow flowers shine for most of the day before dropping in late afternoon. They drop all at once- which is kind of cool. A massive new set of buds will be waiting for daily displays for weeks. Good cold hardiness unless soil in too enriched. Grow this baby mean and lean and you get better performance, a longer lifespan, and better cold hardiness. Hell strips, dry borders, gravel gardens. Light deer resistance. Average lifespan 5-7 years- longer with neglect. Prune after flowering has ended if needed. Excellent shrub for a new garden while you wait for focal plants to establish.
Wonderful little small scale ground cover that delivers tiny blue/gray leaves and masses of small white flower clusters in summer. Semi-woody shrub that rises to only several inches tall (3″) but spreads densely to several feet wide in a circle. Excellent weed suppressing ground cover for tough sites. Light to average summer water speeds growth. Completely cold hardy. Full sun is ideal but you can hedge a little in part shade. Its worth it to prepare the soil and enrich with organic matter- double dig to de-compact the soil and add oxygen. Deep soaks in summer- to establish. Great in parking strips- not a full scale rampant groudcover- rather one that you use for a small area. Small shrubs and perennials can grow through it when planted at the same time. Evergreen. Mountains of New Zealand. Deer resistant. AKA Creeping Rice Flower.
Viburnum japonicum ‘Variegatum’
Unusual and actually superior form of this species with large glossy evergreen leaves splashed with yellow. In spring flat corymbs of flowers appear and remind me of lace. Red berries follow but are consumed by birds. This form is not prone to mildew which can afflict the green leaved form. So, we love it for it’s bold leaves that look good year round and easy demeanor. To 8′ x 8′ in 10 years. Full sun to quite a bit of shade. Doesn’t burn in sun. Adaptable. Light summer water once established. Very old specimens get by with no summer water. Excellent year round appearance. Take out green reversions if they occur. Blooms on wood from the previous season- prune if needed after flowering. Specimen. Nice shrub.
Mahonia euryobracteata ‘Silver Seedlings’
This form of this wonderful Mahonia has leaves that are more silver and a little bit larger than the more commonly seen and finer textured selections of this species. It has also exhibited excellent cold resistance. To 5′ tall moderately fast the finely divided leaves shine. In spring clusters of fragrant yellow flowers are followed by dusty purple/blue berries. Full sun to part shade in average to enriched, well drained sites. Very easy to grow and gorgeous, long lived shrub that consorts with perennials or adds a light texture massed with bolder evergreens. Light consistent summer water speeds growth but established plants are more than drought adapted. Excellent in containers and wonderful winter appearance. Great deer resistance. Forms multiple stems in time to a width almost as tall as it is. These are seedlings from a particularly gray and cold hardy specimen. Easy.
Xera Plants Introduction
Pittosporum tenuifolium ‘Marjory Channon’
Surprisingly hardy and spectacular variegated evergreen shrub for protected locations. Each sage green glossy leaf is margined in white and held on contrasting black stems. Very very pretty shrub to 5′ x 4′ in 7 years. In spring small jet black flowers emerge from the leaf axils. Best surrounded by other evergreen shrubs against a wall or with light overhead protection. This cultivar has come through low’s below 10ºF with only light tip damage and recovery was complete in spring. Slightly tender when a young plant it gains cold hardiness with establishment. Takes pruning very well which will increase the plants density. Great in containers that you protect from lows below about 18ºF. Excellent performance at the Oregon Coast. Do not plant this in a location exposed to strong subfreezing east wind- keep it close with friends. New Zealand. Extremely drought tolerant in full sun to part shade.
Oregon Grape, our ubiquitous state flower. This evergreen shrub can be found almost anywhere aside from the immediate coast to high Cascades west of the mountains. Its native from B.C. to Southern California. Variable shrub to on average 5′ tall and suckering as wide. In rich, happy conditions it will soar to 8′ or more and in more impoverished conditions it makes its life as a spreading low plant. In late February-April the top of the plant erupts in golden yellow incredibly fragrant flowers that are one of the first joys of spring. By late summer these flowers have transformed into clusters of dusty blue incredibly sour fruits. Often employed in the toughest situations where its performance is some what rough. It thrives in cultivation with light, consistent summer moisture. Tolerates heavy clay soils and summer drought. The pinnate leaves often take on purple/maroon tints in winter. Ours are cuttings native to our wholesale nursery site. So its a local plant. Full sun to part shade to quite a bit of shade at the expense of blooming and a lankier outline. Excellent deer resistance when established. Oregon native plant.
Viburnum x burkwoodii ‘Anne Russell’
Really there is nothing like the clove/carnation/sweet fragrance of this shrub in late winter to early spring. The large clusters of flowers begin as pink buds and open to white. Nice bicolor effect along the way. Blooms 3-4 weeks. Evergreen to semi-evergreen to deciduous in arctic places. Large growing shrub that can attain tree like proportions with great age. To 8′ x 4′ in 7 years. Full sun to quite a bit of shade in rich to average well drained sites. Light consistent summer water speeds growth and increases spring flowering. Otherwise relatively drought adapted, especially in shade. Tolerate the most obnoxious sticky clay soils- especially on slopes. Plant where you can pass by the flowers and take a big ol whiff. Very easy to grow. Prune AFTER flowering.
Calla Lily- the dream of many gardeners and an heirloom perennial that has been grown in our region for eons. Large clump forming perennial with dramatic pure white flowers with the familiar form. They begin in early spring with a large flush of bloom and then sporadically until frost. The large boisterous foliage is mostly evergreen and rises to 2′ tall with flower spikes twice as tall. Deer resistant. In cold gardens it is traditionally grown agains warm foundations. But I have seen it thrive in the wide open in the coldest parts of the Willamette Valley. Amenable to saturated soils and can reside as a marginal plant in a pond. Rich, well drained soil is ideal. Water VERY heavily the first summer to establish- then light consistent water in summer. Full sun to quite a bit of shade but at the expense of flowering. Can be a little tricky to establish and ironically it can be a little hard to get rid of once you have it. Lives for many decades. South Africa.
Parahebe cattaractae ‘Miss Wilmott’
Long, long, blooming elegant little evergreen perennial that supplies clouds of white flowers with a prominent plum colored eye. This low growing plant to 10″ tall can spread to 2′ wide in time. Blooms appear from spring to mid summer. The evergreen foliage is handsome for the rest of the year. Full sun and rich, well drained soil with light but consistent summer water. If it gets a bit straggly with time simply cut back 3/4 of the plant in early spring and make sure to water and add a handful of all purpose organic foliage. Very easy to grow in rock garden conditions or the front of a border.
Elaeagnus pungens ‘Glen St. Mary’
Compact Silverthorn is a pretty, tough and useful evergreen in our climate. This form is compact with dense foliage that begins clad in brown fur and settles to silvery gray. The underside of the leaves are pure metallic gold. In autumn small pendant white flowers emit an intense sweet perfume. Noticeable many feet away. Hedges, specimens, barriers. Full sun to part shade with any soil that is never boggy. To 4′ x 5′ in 7 years. The juvenile stage of Eleagnus pungent is a shrub , with great age they can assume the figure of a vine, climbing by large canes that reach upward. These can easily be pruned off to retain a smaller shrub. This slower growing form takes many, many years to reach this stage. Flowers on old wood, prune AFTER flowering. Very drought tolerant when established. Fast growing and easy. Very cold hardy. Japan.
Mt. Etna Broom is a remarkable TREE from the slopes of Italy’s tallest active volcano. Unlike Scot’s Broom (Cytisus scoparius) this fine, leafless tree will NEVER become a pest in our climate. Rush like pendulous green stems are replete with yellow jasmine scented pea flowers for months in summer. This tree casts no shade but provides an elegant vertical element. The sweet perfume travels many feet on a warm day. Blooms May-August. Fast growing drought adapted tree to 18′ tall and 8′ wide in 10 years. Full, all day sun in a hot position in poor to average very well drained soil. Little summer water once established. Forms a very nice trunk in time. Plant with drought adapted shrubs/perennials. Wonderful small garden tree where you need height but don’t want shade. High deer resistance. Slightly tender when very young- fully hardy as an adult (3-4 years). Spectacular in bloom. No shade, it casts no shade.

Lyonothamnus floribundus ssp. Asplenifolius
Catalina Ironwood is a tree locally native to the Channel Islands off of Southern California. Surprisingly hardy once established and older this spectacular evergreen tree in the rose family boasts amazing divided foliage with symmetrical scalloped serrations along each margin. Very pretty. The glossy aromatic leaves are seen to great advantage against the straight, red exfoliating trunk. In spring flat umbels of white flowers appear all over the tree. Fast growing in youth to its ultimate size here 25’+ tall in 15 years. Requires a protected location- such as against the wall of a large building. Avoid direct exposure to subfreezing wind. Little water once established. Wonderful tree for courtyards- protected areas. Fantastic performance at the Oregon Coast. Protect young trees from temperatures below 15ºF- wrap or swaddle in burlap or remay until arctic weather has passed. Reaches its full hardiness several years in the ground. There is a wonderful mature specimen of this tree at the McMennamens in St. John in PDX and scattered large specimens occur around the city. Nice, nice urban tree.
Helleborus x ‘Golden Lotus’ Winter Jewels ®
Spectacular strain of hybrids with fully double flowers. They range in color from lime green to vibrant chartreuse/light yellow. Blooms appear in January and remain showy and effective for several months. The flower retaining their form after they have released their pollen. To 2′ x 2′ forming an expanding clump in part shade to shade in well composted garden soil. Light consistent summer water. Highly deer resistant. Evergreen.
Ribes malvaceum ‘Dancing Tassels’
Really excellent form of Chaparral Currant with 3″ soft pink flowers that appear at any point during winter well into spring. A summer deciduous shrub to 8′ x 5′ in 7 years. Leaves drop completely by September and then re leaf as fall rains progress. Surprisingly hardy for its origin- California’s Channel Islands. Full sun to part shade and well drained average soil. Great on a slope. Loved by overwintering Anna’s hummingbirds. Flowers are surprisingly cold hardy and are undamaged to the upper teens. If those that are open are spoiled by frost more will follow after the thaw. Very very drought tolerant, No supplemental water required when established. Loses most of its leaves in summer drought. Grows fairly quickly and is never a dense shrub- all the better to see the pendant flowers. Dry borders, shrub borders, winter gardens. This shrub loves our climate and is supremely adapted to a winter wet/summer dry regime. Moderate deer resistance. Excellent winter blooming shrub. A beacon to Anna’s Hummingbirds.
Alpine Cider Gum from high elevations in Tasmania has proven to be one of the reliable species of Eucalyptus for our region. Juvenile (young) growth is perfoliate and very very light gray blue- this is the foliage used as popular cut material. The tree may be cut back nearly to the ground regularly to retain this foliage- The tree must be established at least a year before you do this. Otherwise the adult foliage is totally different. Bright green and elongated leaves with a round tip hang densely on an upright growing nice looking tree. Eventually, the bark becomes amazing with pink and gray striations. Blooms in early spring with white flowers. Extremely fast growing tree to 35′ tall + that is a great evergreen garden tree. Good looking year round. Handles ice and snow like a champ- shedding snow and bending under ice without breaking. Full sun and rich to average soil with regular summer water through the first year. High deer resistance. Hardier to cold with age.
Osmanthus heterophyllus ‘Sasaba’
We adore this wickedly armed evergreen shrub. Its a piece of pure architecture. The sharply pointed leaves jut out like blades and are deep glossy green year round. Excellent, interesting evergreen for screen or specimen. Totally cold hardy- excellent performance in blasting subfreezing winds from the Gorge. Rounded, upright shrub to 9′ tall and 6′ wide in 8 years. In autumn the stems of older wood are crowded with tiny white flowers that emit a sweet perfume. Bloom Sept.-Nov. and sometimes later. The fragrance carries quite a distance on mild days. Light water to establish then completely drought tolerant in average, well drained soil. Also accepts the regular irrigation of borders. Good bet where deer are a menace. Full sun to quite a bit of shade. Great barrier hedge.
Hebe venustula ‘Sky Blue’
Very architectural cold hardy Hebe with a tidy upright habit and masses of pale, sky blue flowers in summer. Light green/gold glossy round leaves are congested around vertical stems. Very pretty year round appearance. In time it develops a light tan/gray trunk which contrasts with the deep green foliage. To 3′ tall and usually half as wide for full sun an rich to average- to even poor soil that drains well. Light summer water- though this Hebe can take very dry summer conditions. Cold hardy below 10ºF. Very pretty shrub for tight spaces, rock gardens, borders. New Zealand.
Hebe ochracea ‘James Stirling’
Ochre colored whipcord Hebe that is delightful year round for its deep hue as well as arching swept look of the shrub. To 3′ x 3′ tall and arching for a cool position in full sun- an open north exposure is ideal or part shade. Dislikes hot soil. Best in rock garden positions with great drainage- use boulders to shade the soil. White flowers appear at the branch tips in summer. A true alpine plant from high elevations in New Zealand. Perfectly hardy to cold. Light summer water- never boggy. Grows moderately fast.
Laurus nobilis ‘Crispa’
Wavy Bay tree. Good, cold hardy form of this shrub/tree that is prized for culinary use. Fast growing pyramidal shaped dense shrub to 15′ tall and 8′ wide in 10 years. Full sun and rich, to average well drained soil. Little summer water when established- but tolerates regular water in gardens. Very easy and long lived in containers where you can observe the undulate, wavy edges of the leaves. Protect containerized plants from temperatures below 12ºF. Avoid subfreezing wind. Otherwise a hardy easy to grow evergreen. Give this shrub room- it has greedy roots and is not a good neighbor. Aromatic foliage is also useful for holiday garlands and wreaths. Small yellow flowers are not conspicuous in spring. Moderate deer resistance. Mediterranean.
Pieris japonica ‘Little Heath’
One of the best variegated Pieris on the market. This plant was brought to the U.S. by Gossler Farms in Springfield, Oregon and has gained great popularity. In our experience the ‘little’ refers not to the overall size of the plant- which is eventually large 5′ x 5′- but to the smaller size of the leaves. And each leaf is outlined in white with a darker green center. In full sun this shrub sets tons of chains of pink buds which open to white flowers in Feb/March. The overall fine texture combined with the white variegation gives this plant a very graceful mein. New growth emerges salmon and ages to light yellow before its final destination of green and white. Occasionally shows all green reversions. Simply cut these away. Full sun to quite a bit of shade in rich to average well drained soil. Grows more quickly with regular summer irrigation but established plants sail through summer with a minimum. Very hardy to cold- and tolerates subfreezing wind well.
Little Leaf Gum is a handsome, graceful, cold hardy, obscure beautiful Eucalypt for our gardens. Extremely endangered in the wild it survives in just a few locations at high elevations – always above 3500′, in the SE Australian Alps. That alone gives us reason to grow this fantastic little tree. Fast growing small tree of very fine texture. To 22′ tall and half as wide in our climate. Single or multi-trunked the bark becomes glossy and shedding with time. Remarkably fast growing in youth, easily 3′-6′ in a single season- achieving tree status in just a few years. Wonderful fine textured evergreen that casts the lightest shade. Small groups of white flowers bedeck the stems in late summer and autumn- and sporadically through the year when older. Full sun and an open exposure. Very, very hardy to cold when established. There are two of this species planted along I-5 near the Woodburn Factory Outlets that have been there more than 35 years. They have endured temperatures near 0ºF at least twice in that locale with little to no injury. Takes summer drought but prefers a few good soaks when its really dry. Good garden tree. Dislikes shade. Open exposed location. The tree pictured is at the the Oregon Garden in Silverton. Excellent small garden tree.
Spinning wheel gum is one of the prettiest of the cold hardier Eucalyptus. Named for its striking blue/gray perfoliate round foliage as a juvenile. In time as the foliage morphs to adulthood each new leaf becomes longer and more pendulous. A small tree in our climate to 18′ tall with a widely spreading crown. Fast growing tree, especially in youth. It may be damaged in our coldest winters- losing branches or even freezing to the ground if temperatures drop below about 8ºF. Re-growth which will be juvenile is rapid in spring and it can recover its full height in just two or three seasons. Damage occurs about once every 7 years- and slightly more often in rural settings. Best in the warmest possible part of the garden- and not for cold gardens or subfreezing wind prone sites. Excellent, highly aromatic cut foliage. White flowers line the stems like small sea anemones in winter. In time it develops a strongly weeping habit.
Excellent little multi-trunked hardy Eucalyptus that we love for its height, graceful foliage, and handsome bark. To just 15′ tall after many years it grows quickly when young. The 3″ long medium green glossy leaves are thin and slightly curved. In winter the interior twigs are lined with wispy white flowers in clusters of six. Seldom sets seed in our climate. Excellently adapted and scaled for urban gardens. Very graceful and pretty year round. The leaves are held by vivid red petioles and cut material from this tree is excellent- if somewhat limited from size and slower re-growth. This small tree forms multiple trunks- no single trunk ever happens, and the bark is a soft glossy taupe. Very pretty tree. Related to and included in the category Snow Gum. Hardy without damage to just below 10ºF- and likely much lower.
A classic palm in the PNW. Windmill Palm or Trachys as they are also known are extremely popular. And they should be. Moderately fast growing palm to about 18′ tall in 10 years. The trunk is covered in fur and this acts almost like insulation to protect the interior meristem from cold. Very cold hardy to near short dips to 0ºF- many venerable and ancient Windmill Palms can be found in old neighborhoods having gone through the very worst winters of the last 50 or more years. The fronds usually have drooping filifers on the species but that can vary. Male and female and requires one of each for viable fruit set. Following huge aromatic cream colored flower structures pollinated berries drop and will often germinate in open ground. Full sun to full shade. Drought tolerant but regular irrigation in rich soil will speed growth. Excellent performance in tight spaces. Occasionally young palms become nitrogen starved and turn yellowish. To correct simply feed with all organic fertilizer and mulch and water well through summer.
Dianthus caryophyllus ‘Chomley Ferran’
She’s a strange one this Chomley. Found in a garden in Ireland this amazing carnation is astounding in the color of the flowers. Completely GRAY fully double flowers are streaked throughout with hot pink. I remember several raves in this color realm. Amazing cut flower and easy to grow border perennial. The long stems support the flowers in a vase nicely, but not necessarily when in the ground. Expect some flop. Full sun and average to rich, well drained soil with low/regular summer water. Blooms May-July. To 18″ tall and a little wider. Gray blue foliage is evergreen in our climate. Wowza, Carnations on acid.
One of our favorite trailing succulents for containers. This is a half hardy Sedum (Zn8b) that will persist in most gardens most winters. Rolly poly emerald green foliage takes on dramatic red tints- especially on the older leaves. To 6″ tall and 20″ wide in a season. Rich, WELL DRAINED soil with light summer water. Full sun to part shade. I don’t think I’ve ever seen it bloom and I don’t really care. Trails 1′ over the edge of containers. Mix with other succulents or low water perennials such as Erodium or Scutellaria. Excellent performance at the Oregon coast.
Rosmarinus (Salvia) officinalis ‘Majorca Pink’
We can’t all have ordinary blue flowered Rosemary. Not when there are options. This upright growing very aromatic selection has surprised us with its hardiness to cold. To 3′ x 3′ in 5 years in average to poor, well drained sites. Full sun. This happy shrub displays small but profuse red/pink flowers from September to March and often later than that. Excellent culinary use. Extremely drought tolerant. Little water once established. Great form for topiary. Very pretty in bloom. Foliage is smaller and a distinctive gray green. Moderate deer resistance. Salvia rosmarinus
Juniperus ‘Daub’s Frosted’
If you are going to grow a juniper then it better be good. This useful selection has new growth tipped yellow before turning to blue/green. The outside of the plant is always bright and the interior softer and darker- a happy combination. Low and spreading to 18″ high by 4′ across. Excellent drought tolerant easy to grow evergreen for tough sites. Banks, hellstrips, places where you would rather not have the pets potty. Full sun to very light shade. Regular summer water to establish and then none is necessary. Grows faster in better soil- slower where its impoverished. Either way it will grow and thats what you want.
Lonicera ‘Lemon Beauty’
Dramatic yellow foliage with an interior of deep green on the small evenly spaced evergreen leaves of this low spreading shrub. To 3′ x 4′ and forming something of a mound. Spreads low at first- gains height with age. Rich soil with light summer water in full sun to part shade. Very drought tolerant when established. Lights up borders, is easily clipped- without mangling the small foliage. Flowers are tiny and cream colored often followed by translucent purple berries. Sometimes reverts to all green – just cut those reversions cleanly out. Very easy to grow plant for foundation plantings, tough sites, hedges. There is some confusion over the exact species…if you look it up half say L. nitida and half say L. pileata. I’m going to have to go with L. ??. Shrubby honeysuckle.
Cork oak. The commercial source for high quality cork comes from this evergreen mediterranean native. A large growing tree with a rounded crown. To 35′ tall and half as wide. As the trunk grows (expands) it develops the corky bark very quickly. Harvest correctly and it does not harm the tree. In mid-spring golden tassels eventually become acorns- loved by wild life. Frequently planted as a street tree in the city of Portland. Very, very drought tolerant, in fact it really should not see any water during the summer. Eventually casts a good amount of dark shade. Beautiful tree that is amazingly adaptable to freezing rain and snow. Grows about 2′- 4′ per year when established. Very climate adapted.
Halimium lasianthum ssp. formosum
Big spreading Halimium with arching furry gray stems lined with furry gray foliage. In May-July profuse 1″ wide silky yellow flowers with a basal blotch of deep brown appear massively each day. During the heaviest of bloom the foliage is completely obscured. Flowers last until about 4:00 pm and then the petals drop dramatically all at the same time. Full sun and average to poor soil with little summer water once established. One of the hardiest and easiest to grow. To 3′ x 6′ in just a few years. Very drought tolerant. Tolerates clay soils on a slope. Moderate deer resistance.
Trachelospermum jasminoides ‘Variegatum’
Nice form of star jasmine with large sage green leaves edged in cream. New growth emerges a very pretty pink. From June to August a continuous supply of clusters of sweetly fragrant ivory flowers. To 12′ tall and twining. Provide sturdy support. A nice attribute of Star Jasmines is their habit of keeping their foliage densely to the ground- never any bare knees. Takes full sun to quite a bit of shade- and still blooms. Slightly more tender than the species it requires a protected location- against a wall is ideal. Regular summer water speeds growth and this intensifies the re-blooming. Evergreen. Moderate deer resistance.
Cryptomeria japonica ‘Birodo’
Wonderful easy to grow dwarf form of Japanese Cedar. This form has not scales but more like tiny needles. In summer the foliage is deep green. With cooler weather it takes on amazing russet tints. Very slow growing to 3′ x 2′ in 8 years. Incredibly dense growth habit gives the appearance of diligent pruning- but none is required. Extremely drought tolerant. For full sun and little summer water once established. Rock gardens, containers, gravel gardens. With or without other dwarf conifers. High deer resistance. An excellent truly long term dwarf conifer that retains its good looks. It would make a great no prune hedge that maxes out at 4′ tall but provides density. Very good resistance to subfreezing wind. This performs very well in the Columbia River Gorge and eastern suburbs of Portland. Static form but dynamic seasonal color shifts. Cool.
Gray Pine or Foothill Pine native almost exclusively to the mountains of California- but there are several outlying native populations in Douglas, Josephine and Jackson, Counties in Oregon so we can claim it as our own as well. Known as the tree that casts no shade, its almost completely true as the long gray needles allow almost all light through. Large pine tree with gray foliage- usually forks about 1/2 way up into two main trunks, these are buttressed to support the huge cones which can weigh 5lbs or more. Excellent performance in the Willamette Valley where many are seen around old farm houses and older neighborhoods. Perfectly hardy to cold in our climate and incredibly drought adapted. In fact it shuns all irrigation and is ideal for hot dry locations. Grows very fast in youth, settles down a little with age. Its ultimate height is around 35′-45′ in our climate. A smokey, silvery, shadeless skyline tree. Oregon native plant.
Mahonia nervosa var. mendocinoensis
Rare but excellent form of Cascades Mahonia that is actually found only in the redwoods of N. California to southern Oregon. A TALL upright growing shrub with thick trunks to 9′ eventually. It forms a clump of stems and can increase by suckering closely to the main clump and sending up new stems. Handsome foliage- pinnate dark green leaves to 1′ + long. In winter the whole shrub takes on great plum purple tones. In mid-spring trailing clusters of yellow flowers are followed by blue berries. Moderately slow growing evergreen shrub for part shade to dense shade. Established plants take dust dry conditions in shade. Accepts regular summer water as well- in well drained soil that is not compacted. Mulch each year with a coarse bark. Easy to grow. Appearance is very much like the M. x media hybrids. New growth emerges red. High deer resistance. Oregon native plant.
Grevillea x ‘Marshall Olbrich’
Pretty and very large Grevillea that deserves the mildest parts of the garden. Small gray leaves are handsome and a great backdrop to the hot orange pendant clusters of flowers. Blooms year round with an especially large flush in spring. Loved by overwintering Anna’s Hummingbirds. Not the hardiest Grevillea- protect from subfreezing east wind- site on a south or west facing aspect. To 9′ x 9′ fast. Plant in UNAMENDED native soil- avoid compost and fertilizer. Supremely drought adapted. Avoid watering in summer. Excellent performance at the Oregon coast. Our stock plant which has thrived for 15 years in a very cold place is situated on a slope with the overhead protection of Douglas firs. Evergreen. High deer resistance.
Ophiopogon japonicus ‘Pamela Harper’
AKA ‘Pam Harper’. Nice lily turf that brightens up shady areas with ribbon like evergreen leaves outlined in white. The interior of the leaves is soft green. In early to mid summer 8″ spikes produce lavender flowers. To 10″ x 12″ forming a spreading clump. In time it will spread to form a small scale ground cover. Good appearance year round. Part shade to shade in rich to average soil- including clay soils. Avoid compacted soils and regular summer water speeds up the growth rate. High deer resistance.
Juniperus horizontalis ‘Pancake’
So many junipers and so few that are really interesting. This guy caught our attention for its relatively soft growth (to the touch) that is incredibly dense and flat to the ground (prostrate). In summer the foliage is a soft blue green and in winter it changes to soft lavender buff. Very pretty. Excellent solution for tough dry sites where you need to cover the ground completely. To just inches tall a single plant will spread 3′-4′ wide. Light to little summer water in full sun to very light shade. Easy to grow, useful plant. Nice looking year round. Growth flows around any obstruction- around, up and over. Excellent flowing over rock walls. Moderate deer resistance. This has been used as a groundcover/ lawn substitute and it really does work. As with all ground covers the object is not to cover the whole planet but to cover perfectly the space you need (be realistic) and this plant quickly does that. Pretty at the front of borders and combined with winter blooming Cyclamen coum. In time the stems will layer and aid in erosion control- it takes a few years for this process to kick in. Plant on 2′ centers for a fast and total cover. Water to establish and speed growth and then back off.
Dierama ‘Xera’s Darkest Shades’
We’ve been saving seed from our darkest flowered babies. Its taken us years but we think we’ve got a good mix. Deep purple to dark magenta bells on moderately sized plants. EVERGREEN leaves are gray green and erect. Full sun and rich, well drained soil with ample water in summer. Blooms May-July. To 3′-4′ and then taller in bloom. Little competition from other plants- kind of a diva that way. AKA Angel’s Fishing Rod or Wandflower. Dierama is native to open high plains in South Africa as well as in mountains. Never cut back a Dierama to the ground. It will shock it horribly and may not recover. Instead cut out old or winter damaged leaves and leave the fresh foliage. Highly deer resistant. Regular summer water through bloom then light. Spectacular perennial.
Xera Plants Introduction.
Buxus sinica ‘Sunburst’
Useful and pretty and so tough this is a yellow variegated form of Korean Boxwood and its a fantastic dwarf shrub. To just 2′ x 2′ in 7 years this slow growing evergreen shrub is ideal as a hedge or trim it into a crazy shape and make a focal point. Adaptable to full hot sun to part shade. Great in winter containers. Hardy way below 0ºF. A good shrub or hedge in cold gardens or areas blasted by subfreezing east wind. Very good deer resistance. Light summer water in rich, well drained soil. Avoid crowding/shading from other plants in too close of proximity. Easy to grow- good looks year round. For a hedge plant on 2′ centers.
