This is a strain of Agapanthus from the very cold hardiest varieties that we grow. Not only are these perfectly hardy to cold they are naturally completely deciduous. Even better they wait to emerge until all danger of frost has past. Many ‘hardy’ CA varieties leaf out in the false spring of late winter and then get nipped hard by possible late freezes. Not at all fussy about soil but best in enriched soil with light consistent summer irrigation. Large globes of rich sky blue flowers are bigger than a grapefruit and wave at the top of 3′-4′ stems. Quite a bit taller than other hardy varieties. Full sun to very light shade and not fussy. They will live in containers for eons and bloom like crazy. Flowers appear from late June to early August and are very showy. This is a very pretty tall strain that is reliable and kind of hard to F up. If you’ve lost Agapanthus in a cold garden or unfortunate freeze this is the one to try. As with all Agapanthus they thrive and bloom in neutral to alkaline soil. Incorporate a handful of lime in the hole at planting time. Strappy clumps of mid-green leaves are handsome following bloom. As the plant multiplies it increases its blooms stem count markedly.
Xera Plants Introduction
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 white 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.
A really interesting and wonderful vine that we grow as an annual but its a perennial in warmer climates and can be here too if you treat it right. Arrow shaped leaves have modified petioles that attach and hoists this climber to 8′ in a single season. A continuous supply of tubular (snapdragon shaped) purple blue flowers with a white throat. Loved by hummers this native of the driest parts of the mediterranean is adapted to being dry in the winter and wet in summer. If wet and saturated the whole vine is only hardy to about 26ºF. However, if the plant is kept dry in the winter it is hardy to MUCH colder. In a former garden I had it planted against the south facing side of my house under the eaves. It was bone dry in winter and to my shock it lived for 7 years with temperatures down to 10ºF. I offer this information as interesting but its a primo delicate vine with beautiful flowers that appear continuously all season which makes a lovely seasonal bower. Great on a tripod, or teutier in containers. Full sun to very light shade in rich, well drained soil. Excellent on spring blooming shrubs that are quiet in summer- its a fine textured plant that will never smother the host. Excellent plant.
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.
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.
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.
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
Big, bold, and hardy, this is the cold hardiest Elephant’s ear that we’ve yet grown. Large (14″ long by 9″ wide) leaves with a distinct black dot in the center- the pearl. Large growing perennial to 4′ tall and running underground to spread as wide. Rich, moisture retentive soil with regular summer water. Excellent companion for other bold leaved plants- such as gold leaved Acanthus. Excellent for tropical effects w/ no fear of freezing out. Root hardy below 10ºF when clumps are established Give this large plant room to spread. Easy to grow for the most part. Goes deciduous with the first frost and emerges late in spring when the soil truly warms. Be patient. Not bothered by pests. Mulch for the first autumn. Great for big subtropical effects. Tolerates shallow water, but is not as hardy to cold.
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.
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.
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 area 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.
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
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.
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.
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
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. Pairs well with Madrone and Arctostaphylos. Oregon native plant.
Xera Plants Introduction
Mountain garland is a hardy annual native to the mountains of southern Oregon south into the Sierra Nevada in California. Sparkling white crape-like flowers line tall upright stems on this plant that can be small in poor soil and soar in rich conditions. Size can be difficult to determine based on this…an average of 1′ tall is probably safe. Blooms continuously from May to as late as August if supplemental light water is supplied. Excellent among perennials such as Penstemons, Erodiums, Salvias, Cupheas. Sets copious seed for the following season and these will be white as well. Leave open disturbed sites in your garden to supply next years crop. Excellent cut flower as well and loved by Butterflies. Very easy to grow.
Oregon native plant
Lovely ubiquitous woodland flower that brings waves of glorious airy stars for weeks in late spring to mid summer. Occasionally pink the flowers most often are white. Handsome somewhat bold foliage provides a plant that is more than suited to competition on the forest floor. Often self sows and this is welcome. Plant containerized plants in spring and water faithfully through the first summer- but never boggy. Then it is yours. Let it romp among ferns, Hosta, Japanese Forest Grass for a sparkling NATIVE treat. Mix with other natives such as Vancouveria and deer fern. Very easy to grow. Blooms for a very long time and longer if we have a cool beginning to summer. AKA Candy flower. To 10″ x 10″ on average. Summer deciduous and emerges early in spring. Not bothered by pests. Forms spreading colonies in rich, humus enriched soil in part shade to shade. Locally native in the Portland city limits. Oregon native plant.
Great Hounds Tongue or Giant Pacific Forget-me-Not is one of our most remarkable native perennials. On the property where I grew up near Eugene it was native. There was a clump of this majestic perennial that was there for nearly my whole life. Unfortunately, we sold the property but this plant was still there last I checked. In the Willamette Valley and out into the Columbia Gorge you see these enormous blue flowers on a sturdy spikes in the dry areas under oaks. Often seen with Wyethia -Mules ears. Large fleshy leaves form a substantial clump. In early to mid spring 2′ spikes reveal outrageously large versions of Forget-me-nots. Established plants will then go dormant with summer drought. Adapted to xeric clay soils that dry in summer. Not only does it not require it established plants can resent it and rot. Place in a wild, unwatered part of your garden. Amend the soil lightly with compost and water in well. Pairs well, of course with other native perennials such as Sidalceas. In the wild it is accompanied by Erythronium oreganum , Lathyrus nevadensis, Fritillaria lanceolata, Dodecatheon hendersonii, and Ranunculus occidentals. That is what grew with our patch, under white and black native oaks, with a madrone here and there. Impressive native perennial whose intense blue flowers are hard to convey in a photograph. Oregon native plant.
Our selection of a superior deep black leaved Dahlia. Finely divided leaves are symmetrical on towering stems to 4′ tall. In mid summer to fall a constant procession of vibrant red single flowers. They harmonize greatly with the leaf color. Full sun and enriched soil with regular summer water. Soil that does not become sodden and frozen in winter will yield the cold hardiest plants. Mulch in fall. Nice cut flower, arrangement material. Multiplies into large clumps in time. This selection has survived the coldest winters of the past 15 years. We’ve kind of let Jack frost do our selecting for us.
Xera Plants Introduction
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 appearing plant out of bloom.
A wonderful garden perennial and by far our favorite mum for fall. Much more informal and relaxed in habit and flower form it puts on a stellar show for months in autumn. Soft, copper pink single flowers radiate from a soft yellow center. A bushy perennial to 28″ x 28″ in full sun to light shade. Best in enriched soil for a good start in life. Regular summer water propels growth and blooming which begins in September and stretches nearly to Thanksgiving. Cut back hard the previous years remnants in early spring – as per your tidying routine. Very pretty cut flower. Underplant with Ivy leaved hardy Cyclamen for a soft but showy display. Long lived perennial gaining scale each year. Moderate deer resistance. Aromatic curly foliage is classic Chrysanthemum.
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.
The bodaciously named Chilean Glory Vine is a great low weight, long and strong blooming perennial vine in our climate. Filligree intricately divided leaves and petioles wind this deciduous vine up to 10′ in a season. Most years it returns to the ground and resprouts in spring and that isn’t a bad thing. It gives you the opportunity to clear away the previous seasons chaff. If we have a mild enough winter it will retain some green but you may still cut it back in early spring. Waves of long stemmed tubular flowers are soft pink with a recurved lip tipped in yellow. Its an exquisite show that goes unabated from late May to September. We’re very attracted to this orchid like coloration of this form and we find it accommodating for mixing colors. It also comes in red, orange, yellow, and cream- in time we will offer those. Hummingbirds LOVE this vine and will immediately show up when flowering commences. Much easier than cleaning and refilling a feeder. Remove spent flowers and that will encourage more flowers. Blooms on new growth. As it grows it blooms. Fantastic on the wall of a chicken coop providing ample shade. Rich soil that drains and regular summer water. Mulch the base- protect the crown in the first winter.
A beautiful color form of California Fuchsia with kind of a creepy name. No idea who named it. But this is a very long blooming, low, spreading perennial with downy gray green foliage and a constant procession of tubular peach/pink flowers. Loved by low flying hummer’s this plant is ideal for hot, locations in soil that never becomes boggy. To 6″ tall x 2′ wide and forming substantial patches in full sun. Excellent performance in hell strips. Most Epilobiums (Zauschneria) in our climate are drought tolerant but they perform better and are showier in bloom with light, occasional summer water. Water during the driest times of the year about once every two weeks. Blooms begin in late July and are resplendent well into autumn. Great long term performance in large containers, planters. Winter deciduous. Remove frost damaged tops when frost kills them. Best to match the vigor of this perennial with vigorous neighbors. It can swamp shy plants. Excellent in rock walls, at the top of walls. Combine with Sedum palmeri, Helichrysum thianshanicum, Chocolate cosmos for a community of perennials with identical requirements. Winter deciduous. Spreads laterally by underground stolons. Give Woody some room.
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.
True pink California poppy. Seed from this exceptional pink flowered selection comes true about 95% of the time. Deep rose pink semi-double flowers appear in late spring and continue sporadically until mid summer. A happy plant can become a short lived perennial but the majority will behave as bloomy annuals. Full sun and rich to average soil with good tilth (crumbly texture). It can even thrive in compacted soils. To 10″ x 10″ forming a compact plant with lacy blue foliage. The strident rose pink flowers are showy from a distance. Leave the last round of flowers to seed for the next several seasons. Excellent wildflower display in rough areas w/ low water. Water plants to establish then taper off. Remove spent flowers to encourage more. Wonderful flower color. Mix with Eschscholzia c. ‘Alba’ the white form. Deer resistant and drought adapted native plant. Oregon native plant.
Xera Plants Introduction
One of my favorite separate strains of CA poppy. ‘Purple’ gleam is a tiny bit of an over statement. More accurate its pink w/ purple overtones and a lighter center. Blooms from April August in a wave of big flowers that tossles over compact plants with filigree blue foliage. Full sun and average to even poor soil. Often potted Eschscholzia will perennialize and live for a year or two in the ground. Otherwise its an annual and will succumb when the whole plant blooms itself out. To 10″ x 12″ forming a spreading plant. Remove spent flowers to continue the show. Many plants will take a break over summer and then resume blooming w/ cooler autumn rains. Great pollinator plant. Containers, dry areas, borders. Reseeds reliably w/ about 80% true to parent type. Wonderful with Clarkia unguiculata ‘White’ and Collinsia grandiflora. High deer resistance. Leave open disturbed soil for it to reseed. Light summer H20. Oregon native plant
We love ultra hardy Fuchsias, they are so carefree and they bloom and bloom. We found this Fuchsia in a garden near our shop. It was identified by our friend Annie Hayes at Annie’s annuals. Large growing subshrub to 5′ x 6′ in time. Red sepals surround a deep purple corolla with each petal marked with a strip of hot pink. Lovely. Flowers are large for a hardy Fuchsia and are profuse from June to frost. Fuchsia mite resistant. Very easy to grow in light shade to full sun. Rich, well drained soil with regular summer water is ideal. Very established plants can make due with less. Freezes to the ground in the low 20’s- but not every year. Wait until new growth emerges then remove the frozen material. Loved by hummingbirds as well as gardeners. Lustrous deep green foliage outlines the pendant flowers. You’ll never lose this long lived plant to winter. Good to try where rabbits are a problem.
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.
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.

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. 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
Excellent selection of a long and fantastic summer blooming perennial. We’ve shied away from this genus because it does like regular water to look its best. That having been said, where you see our native Helenium bigelovii, it sits in riparian zones and along the edge of permanent and intermittent streams and in wet meadows. This selection is an exciting color break. Developed, chosen, and named at Rogerson Clematis Gardens here in Lake Oswego, OR. They obviously don’t just do Clematis- but if you have never been its one of the premier gardens in our area. Hardy perennial to 30″ tall from an expanding fairly dense clump. In a season or two it reaches about 1′ across at the base. Wonderful flower color that is sumptuous and it blooms for many weeks. 4-6 weeks in late July, August, and early September. Excellent cut flower and it has a perfect scale for the middle of a well irrigated border, in full sun and rich soil. Loved by pollinators- and perfect for butterflies to land and feed. Long lived and winter deciduous.
Xera Plants Introduction (Via Rogerson’s Clematis Garden)
A really cool form of Oak Leaf Hydrangea that I picked up in North Carolina. Full double thick, dense white flower spikes appear in place of the lacier form of the species. The dense cones of flowers appear on sturdy stems in late June and are effective until September. They are exceptionally showy as well as long lasting. Large, deciduous shrub for full sun to part shade in rich soil with consistent summer moisture. Very established plants can get by with less. Blooms on wood from the current season. If pruning is required do it in early spring. To 9′ x 9′ in 6 years. Fall color on the immense leaves is remarkable. For all the months of fall into mid-winter purple/red/orange tones wash over the whole plant. Leaves finally abandon the shrub in mid winter. Easy to grow wonderful multi-dimensional shrub that is cold hardy and durable. Give it room to spread, you won’t regret it. Yay ‘Turkey Heaven’. Limited supply. Native to the SE U.S.
Bare stem biscuit root is a locally native perennial that is found in rocky dry areas among clumping native grasses. The stemless rosette bears upright entire glabrous blue leaves. 6″ stems rise up in late spring to earl summer with umbels of sulphur yellow flowers (sometimes purple). To establish, water thoroughly through the first month in the ground. Winter deciduous it emerges very early in spring. Loved by pollinators of all kinds. In the Willamette Valley this biscuit root grows in various biomes but is most common on dry hillsides. Festuca californica and Festuca roemeri are two native grasses seen with this plant in the wild. Full sun to light deciduous shade. Avoid standing water in winter. Long lived perennial once established. Excellent in gravel gardens. Leaves remain handsome after blooming. Spreads slowly to form colonies. Locally native in the Portland city limits. Drought adapted when established. Moderate deer resistance. Oregon native plant.
PNW Orange Honeysuckle is one of our most showy native vines. Our region is sparse on native vines so this pretty plant is welcome. In late spring to summer clusters of brilliant orange tubular flowers decorate the branch tips. Loved by hummingbirds as well as other birds which is obvious, its also important for all native pollinators. The flowers change to brilliant red fruit which is consumed by wildlife and seldom lingers. Deciduous mid green foliage is verdant all through the season. As with the vast majority of Honeysuckle vines this plant nearly always goes leafless at the base. Expect this and plan for it. Strongly twining plant to 12′ tall and almost as wide. Provide strong support. Light consistent summer water to establish then very little necessary once established. (Also accepts regular summer H20). Excellent vine for country fences, decorating mailboxes etc. Protect from deer, otherwise it is pest and disease resistant- occasional mildew in the autumn is virtually harmless – great news for a honeysuckle. Blooms on wood from the previous season, prune if needed after flowering. Oregon native plant
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.
Probably the best looking and easiest to grow lily turf species for our climate. Tightly clumping deep green grasslike mounds of foliage are good looking YEAR ROUND- no scorching or freeze burn. To 8″ tall x 10″ wide eventually it thrives in quite a bit of shade to even sun if irrigation is consistent. Loves heavy clay soils and will happily live in standing water for part of the year. Established plants (1-2 years) are much more drought resistant even in full sun. The glossy leaves are just 3mm wide and 10cm long. In summer masses of white flowers appear within the foliage. These turn into masses of large, vivid sky blue berries which are showy well into winter. Excellent for massing (plant on 8″ centers) for a small scale ground cover. For this application it plays to amend the soil with compost and all organic fertilizer to speed growth and establishment. Excellent as a marginal plant near natural ponds and creeks. Very deer resistant. Native to eastern China.
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.
Sumptuous zonal geranium with deep black and green foliage and vibrant coral pink flowers non-stop for months. To 20″ tall and as wide. Seems to go up for a while but always ends up with horizontal stems. Blooms heavily and constantly- Very pretty delicate appearing flowers. This is a fantastic zonal for containers, its thrives in rich soil with regular irrigation. Rich, soil that drains. Add a table spoon of all organic fertilizer at planting. This guy loves food. Tender to cold. Over winter in an unheated but not arctic garage or try something new next year. This plant has become a real favorite of ours. Its also a fantastic conservatory plant and might work as a houseplant in a very sunny window. Full sun to very light shade.
Sea Blush, or more commonly Rosy Plectritis is a locally native hardy annual in the Valerian family. In April-June it swarms meadows and glens with orbicular globes of dense fragrant pink flowers. They rise on average to about 10″ tall. Rich soil will yield larger plants. Excellent bulb cover for late narcissus, tulips etc. Fun to grow heavily reseeding annual that also makes a sweet cut flower. It can be found in the western third of the state. Also wonderful with Pacific Coast Iris as they bloom concurrently. Sets seed and dies by mid summer when the spent carcasses may be removed- when doing that give them a shake where you want next years display to occur. Make sure not to cover the seed, native annual seed requires light to germinate and it will very quickly sprout with the first cool fall rains. Traditionally, Rosy Plectritis can be found in a mix of perennial and annual communities. In its many habitats it can be found with Oregon Iris (Iris tenax) and often Giant Blue Eyed Mary (Collinsia grandiflora). Water to establish as plants- then none. Full sun to very light shade. New seedlings have paddle shaped true leaves with a rubbery texture. High deer resistance. Native in the Portland city limits. Oregon native plant.
Slender Cinquefoil is a common, somewhat quiet but easy to grow long lived native perennial. Palmate leaves are conspicuously serrated on long stems. In early to mid summer 20″ stems support multiple clumps of sunny single yellow flowers. Full sun to part shade in average to enriched soil. Water to establish the first season then let it go with seasonal rainfall. Wild looking perennial that shines in borders, among shrubs and along the urban wild lands interface. Very pretty clustered at the foot of Holodiscus whose bloom is simultaneous. Loved by pollinators and an important food source for many butterflies. Native from SW. British Columbia south to San Diego County California. Often found in Ponderosa pine forests. Blooms much more heavily in full sun and improves under cultivation. Winter deciduous. Little deer resistance. Rose family. These are seed raised from Willamette Valley populations so it is the local form. Oregon native plant.
Western Buttercup is our own wonderful wildflower. This is the real thing and NOT the invasive Ranunculus ficaria or repens. Traditionally it occupies open Oregon Oak woodlands and meadows including vernally wet meadows. Though it handles winter inundation it is also adapted to upland situations and in every biome it goes quickly summer dormant. Rosettes of pretty pinked leaves elongate in bloom to an airy spray of bright yellow flowers. Intimately, the petals have a glossy sheen. And growing up in the country it was traditional to put a picked flower under your chin and the reflected color yellow revealed that indeed you did like butter. Great cut flower that peaks on May Day and has made many a wild flower bouquet with purple Oregon Iris and purple Dodecatheon hendersonii- Shooting stars. Pictured here with Common Camas Camassia quamash at the Camassia reserve in West Linn, Oregon. Blooms from mid-April to early June. Vast meadows of western Oregon still harbor this sweet short lived perennial. Adapted to heavy clay soils- reseeds when happy. Suitable for mowed meadows as long as it has gone to seed by the time you mow. Wait until June. Good competitor with invasives and absolutely integral to a Willamette Valley meadow. High deer resistance. Oregon native plant
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.

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.

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
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.
This is red, no pink, very little orange, true blasting red. Our employee Chris thought we needed it and after observation I heartily agree. Bushy semi-woody perennial to 30″ x 30″ for full sun and rich well drained soil. A slope is best. Blooms unabated from May to frost. It takes a break in temperatures above 97º but resumes blooming with a cool down. This is redder ( with no white) than Hot lips with very large flowers in deeply colored calyxes. We have been impressed with the cold and wet tolerance of Salvia microphylla. Of utmost importance is to refrain from cutting them back until all danger of frost has passed, then you can go for it and regrowth to bloom is rapid. Obviously a hummingbird attractant. They stake them out, they fight and its all good fun. Long blooming Light deer resistance. Drought adapted when established.
Graceful and formal at the same time. This low arching form of winter box is wonderful with curly 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. 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. Nice plant. China.
Rare native perennial that can be found in wet marginal areas along the coast from Oregon to S. Alaska. Never common it forms large clumps of verdant green scalloped foliage and towers of deep pink hollyhock-like flowers. The flowers are arranged densely on the stem.

Very good with border delphiniums or even Penstemons. Tough long lived plant given the correct site. Climate adapted perennial. Rare. Cut back spent stems in winter. Oregon native plant.
This seedling of the millions of Tiarellas that we’ve grown over the years is a stand out. Found at the edge of a shade hoop house it thrived for years before I realized, this is a really good plant. Palmate leaves are widely divided and stamped on the center with black. An edging of green surrounds this imprint. From mid spring to summer a continuous supply of spears of flowers that are tinted pink and open to white. Spreads to form prodigious colonies in rich, moisture retentive soil with regular irrigation. Lovely plant that brightens woodland in part shade. An annual top dressing of compost is greatly appreciated. To 1′ tall in bloom and leafy clumps spread out to several feet wide. Excellent along stream banks, ponds spreading love in dappled light.

Is this hardy? Why, yes, yes it is. Mexican Shellflower or just Tigridia is a fun bulb that produces large, immensely showy flowers that last but a day. Three large petals emanate from a wildly speckled center. White, red, orange, yellow, and pink flowers are all represented in this mix. Rich, well drained soil in a warm position- mine are on the south side of my house in average soil and they not only multiply year to year they self sow.

A pretty spreading spring wildflower with heads of brilliant magenta/purple flowers. Blooms in mid spring to early autumn. 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.

We love Violas, so fresh and pretty during cool/cold weather. This enchanting strain is hard to describe. It comes in a multitude of colors and color combinations, each flower looks like it has been freshly stroked with a wet water color brush. Adorable and whimsical flowers with a light fragrance for full sun to light shade and rich soil. Consistent summer water will often get them through the most torrid times. Otherwise we have found this to be a lovely group to plant in fall for winter to spring color. Nice little cut flowers. Each plant is completely unique. Reminds me a bit of Tye Dye or Batik. Very easy to grow. Lovely in mixed containers.
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.
