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.
Plants with Deer Resistance
There is nothing more frustrating than deer devouring your garden. Deer are a lot like people, they will try anything, especially if its new. So, while there are no plants that are 100% deer-proof here are some selections from our plant list that have proven to be less often on the menu. Of course a fence is always the best defense.
Tip: pay attention not just to the species but the genus as well. Though not 100% impervious, some are much less prone to consumption than others. Pay attention to what they don’t eat, for instance they seldom eat Digitalis therefore, it would be prudent to try other species of Digitalis rather than moving on to a completely different genus. You’d be surprised the choices that you have. To extend that line of thinking. Notice that deer seldom bother Boxwood, therefore it would be wise to try other plants in that family (Buxaceae). You might be surprised to find that Sarcococca and Pachysandra are both in that family and their deer resistance is good too. A few other families that share deer resistance are the Iris family (Iridaceae), Ferns (Dryopteraceae) and Daphne, (Thymelaceae). Remember that you don’t know if they will consume it unless you try and deer have tastes that not only vary they can also change.
If you don’t feel like springing for a fence and you insist that Bambi shine free I’ve had relatively good luck with 1cm x 1cm black bird netting, It can be stretched around tree trunks or posts to provide some measure of protection, and it is almost invisible from a distance. The downside is that deer can become tangled in it and UV seems to break it down. But as a temporary barrier it has merits.
More considerations:
Deer will seek out irrigated plants during the driest parts of the year (wouldn’t you?)
Newly installed plants are often more vulnerable. It’s a deer- it can’t tell the difference between your new favorite plant or an offering of food.
Deer will rut on plants, often small trees- they should be protected if vulnerable. Surround with sheep wire to 6’ tall. Rutting is to remove fur from their antlers and to leave their scent. Either way it really screws up trees when they rub off the bark and branches especially if the tree is very young.
Deer do what nature tells them to do- not to piss off gardeners- innovation and patience are your responsibility.
Climate Adapted Plants for Gardeners in the PNW
Acacia spectabilis
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.
Acanthus syriacus
Outrageous Bear’s Breeches for hot and sunny aspects. Forms large rosettes of spiked intricate leaves that almost lay flat on the ground. In summer, enormous chalice-like soft purple blooms rise to 2′ tall. Each flower opens to reveal yellow petals. A beautiful combination. Full sun and rich, well drained soil with light summer water. Give this plant room and air circulation. It does not like to be crowded. Fully cold hardy and completely winter deciduous. Established plants can get by on less water. Moderate deer resistance. To 2′ wide in several seasons. Spectacular cut flower.
Acer glabrum ssp. douglasii
Rocky mountain maple or locally also known as Douglas maple is our form of a widespread and sweet small tree that ranges from the Yukon in Canada to the highest mountains of northern Mexico. Our local variety is found in all of the mountainous parts of the state. This demure tree is the least planted of our native maples and deserves much more inclusion in our gardens. In the coast range it is found primarily above 2000′ and it can even be found lower in the Cascades. It follows the spine of the Ochocos in eastern Oregon up into the Blue mountains and Wallowa Mountains in the far north east. Rarely pole straight in stature its often multi-trunked and single trunked trees are in the minority in the wild. Ours are single trunks but multiple stems do not take away from the fresh green leaves and pretty to stunning fall color. The familiar maple leaves can achieve anything from dull yellow to shots of vermillion. Depending on the weather and tree. Soft gray bark. To 25′ tall moderately fast. Tiny green flowers morph into rosy hued samaras in autumn. Regular water for the first several years. This tree does appreciate rich soil that retains moisture in the Willamette Valley. Excellent woodland tree or even more appropriate on the edge of a stand of trees where it receives at least half a day of sun. The most recent years stems are often sanguine red, nice contrast with the grass green elegant leaves. The most striking fall color is achieved with more sun. A mesic maple that often follows water courses or lines wet ground. Single trunked trees are conical shaped and multi-trunked forms are more rounded and spreading. Deciduous. Avoid blasting heat and drought. Oregon native plant.
Achillea millefolium
This is the green foliage form of our wild yarrow. A rambunctious, easy to grow evergreen perennial for rough sites in well drained soil in full sun. Continuously from spring to autumn ‘umbels’ of pure white flowers rise 18″ above low spreading aromatic, finely divided ferny foliage. Most often it is green with variants that have gray foliage from time to time. Low water perennial that can even be used as a lawn substitute. A single plant spreads to several feet wide. Moderate deer resistance. Butterflies oh the butterflies.This is a pioneer perennial and will often out compete less robust native perennials. Its best use is as a contained weed. It is great for pollinators Individual plants rarely persist more than 3 years. Oregon native plant.
Achillea millefolium ‘Pretty Woman’
Of all the selections of our native yarrow this stands out for many reasons. The ‘umbels’ of flowers are a rich red which holds the color for an extended period. It fades only slightly to a rust red with time. Its vigorous and easy to grow. And it re-blooms reliably if spent flowers are removed. All the way until frost and sometimes longer. A very, very good long-lasting cut flower. To 18″ tall forming spreading colonies. Semi-evergreen. Low water when established in well-drained soils. Excellent to moderate deer resistance. Appreciates an annual application of compost. Oregon native plant.
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.
Achillea millefolium ‘Willamette Gray’
Greg got seed of this distinctive form of Yarrow near Oregon City. Unlike most garden varieties that are derived from European stock which very much appreciates rich soil and regular water to perform and those forms are also not pungent. We wanted our locally native yarrow that is incredibly durable, has gray foliage that is pleasantly aromatic with broad white flowers. This is a much more climate adapted perennial. Its found throughout all of the state, and can be found anywhere from meadows to surprisingly deep woods. This is a very thrifty plant and once established it really doesn’t need supplemental summer water. Spreads to form finely divided low gray foliage. The flat umbels of pure white flowers are very large and this is a landing pad for all pollinators as well as butterflies. To 20″ tall in bloom. Excellent meadow component with clumping grasses, annuals, and bulbs. A great plant for hell strips and hot aspects too. Very easy and forgiving perennial. Blooms May-August. Mostly evergreen save for the very harshest winters. Not bothered by deer. Oregon native plant.
Xera Plants Introduction
Achillea sibirica
A wonderful relatively new Achillea (Yarrow) from Siberia. It brings not only larger chalk pink flowers in bold umbels it is cold hardy to USDA Zone 2. This plant will never freeze out. Forms expanding clumps with upright stems clothed in glossy long green leaves with small teeth. On 22″ stems umbels of flowers appear from May to August. After the first flush of flowers shear away and water and another round will commence. The long stems make great long lasting cut flowers too. Loved by a bazillion pollinators, hover flies, bees of all kinds swarm the flat landing pad. Full sun to very light shade in rich, soil that drains. Incorporate some oxygen in by double digging. Good companion plants are Agastaches and Penstemons as well as ornamental grasses. Completely deciduous in winter. Light consistent summer H20 to establish. Long lived perennial. Moderate deer resistance. Elegant perennial. Siberian Yarrow.
Acorus calamus ‘Variegata’
Nifty foliage perennial that can double as a terrestrial border plant (with regular water in rich, moisture-retentive soil) or submerged as a border perennial in a water pot or the edge of the pond. The majority of the spikey 3′ tall leaves are composed of cream/ivory streaks with dramatic stripes of deep green. The effect is ghostly and vivid from quite a distance away. Forms large spreading clumps in time. To 4′ wide when things are going well. Full sun to part shade. Flowers are not very conspicuous spikes that hide within the foliage. Completely winter deciduous- this is nice, it makes cleaning up in late winter/spring easy and and no fuss and the plant begins anew and fresh each season. Not bothered by pests. If sunk in a pond or water pot use heavy clay soil- like from the ground and mulch with a layer of gravel. Long lived plant. High deer resistance. AKA. Ghost Sweet Flag.
Acorus gramineus ‘Golden Lion’
Is this the best form of golden sweet flag or what? We love the vivid yellow leaves on a dense and arching evergold perennial. Clumps densely but the foliage is born in fans and spreads out. To only 6″ tall but spreading to 1′ wide. Best in part shade and either permanently wet sites or regular consistent water. Mine makes a happy home on the north side of my house at the base of the rain gutter. Plenty of water in winter- and I don’t forget to water it in summer. Good appearance year round. In spring little off-white spikes serve as flowers. Native to permanently wet sites. Give it a bit of shade. Moderately deer resistant.
Adelinia grande
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 luminous blue flowers on a sturdy spikes in the dry areas under oaks. They usually senesce to pink. Often seen with Wyethia -Mules ears which blooms later. 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 water established plants can resent it and rot. Place in a wild, shady, unwatered part of your garden. Amend the soil lightly with compost and water in well. Pairs with other native perennials such as Sidalceas. In the wild it is accompanied by Erythronium oreganum , Lathyrus nevadensis, Fritillaria affinis, Dodecatheon hendersonii, and Ranunculus occidentalis. 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. It takes an extended time from seed to a growable plant. Patience because of limited quantities. SLOW Oregon native plant.
Adiantum venustum
Himalayan Maidenhair fern is one of our favorite groundcovers for shade and rich, moist soil. The divided fronds in the shape of an arrow are always soft and fresh. In spring this deciduous variety emerges with tones of amber and soft pink before taking on a mature soft green hue. These delicate leaflets are held on thin, wiry black stems to 10″ tall and it spreads prodigiously to form vast colonies. It doesn’t smother neighboring plants however, instead it seems to just flow around such woodland neighbors as Epimedium, Hellebores, even woodland bulbs like Erythronium. Regular summer water. Avoid hard, compacted dry soils. High deer resistance.
Agastache ‘Electric Punch’
One of our all-time best introductions ‘Electric Punch’ is a floral powerhouse of a hummingbird mint with exceptional adaptation to our cold and wet winters. Rising to 34″ tall in bloom, a clump can become enormous in rich, WELL DRAINED soil with light, consistent summer water. Also, accepts no water but with interruptions in bloom. Incorporate plenty of oxygen into the soil and slopes are ideal. Do not remove flower spikes during the season- new orange aging to pink flowers appear from the same inflorescence. Best to wait until spring to cut back the previous seasons defunct stems. Moderate deer resistance. Agastache are best watered well for their first season, in subsequent years they will use much less.
Xera Plants Introduction.
Agastache pallida ssp. neomexicana
Cute flowering hyssop that makes a clump of strongly vertical stems clad at the tips with soft mauve/purple flowers. A boon to pollinators as well as hummingbirds. Blooms June to October continuously from the same spikes. To 18″ tall and barely half as wide. Agastaches like light soil. Double dig the soil well to incorporate oxygen and apply a handful of all organic fertilizer at planting. This will establish the plant much faster. Excellent performance on slopes where it achieves the drainage that it likes. Middle of the border or massed in a meadow- this easy to grow perennial performs for a long time. Do not cut back until after Valentine’s Day. Consistent water for the first summer then light water in subsequent years. Excellent performance in mixed container plantings. Moderate deer resistance. Foliage is sweetly pungent.
Agave bracteosa
Far and away the easiest Agave to cultivate in our climate and the handsome contorted sage green leaves are free of a deadly spike at the tip. Don’t be fooled, though. The leaves are lined in fine serrations that can cause a cut if you rub your person against them. To 3′ tall and as wide for very well-drained soils in full sun to very light shade. Amend the soil with pumice to sharpen drainage if needed. Ideally adapted to slopes. Good dimensions as a large focal point in a rock garden or clustered into clumps in the gravel bed. Accepts the highest reflected heat. Light summer water speeds growth. Often produces offspring from the base. These can be detached and replanted when its truly warm. Bold mature clumps are breathtaking. Wonderful life in hellstrips. Obviously deer resistant, but the tips can be brittle so handle them with care when planting. Excellent year round appearance and texture.
Agave harvardiana
Spikes! A very upright and pokey Agave with steel blue/gray foliage that forms large rosettes. To 3′ across eventually this cold hardy Agave demands excellent drainage but is worth the effort. VERY well drained soil- amend with liberal amounts of pumice and gravel. Excellent on a slope. Plant with the rosette tilted to shed winter water. Makes new pups happily and they will often come up quite a distance from the parent plant. To 3′ tall when up and established. Great in containers that you protect from winter wet. Move to a covered place in fall- a south facing eave is sufficient. Cold hardy below 0ºF- when established. Best to plant in March or April so that it has the longest possible season to develop a root system going into its first winter. Light summer water to none. High deer resistance.
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.
Agave parryi ‘Flagstaff’
From the very far north end of this variable species range in Northern Arizona near—‘Flagstaff’. High elevation form that is found above 7000′ in the wild. Very cold hardy moderately large Agave. Full sun and very well drained soil. You must amend the soil with pumice and gravel to avoid wet accumulating around the crown in winter. This is made all the more easy by placing on a slope. The rosettes should be tilted to shed winter wet. Very stiff and sharply tipped steel blue leaves form a rosette that is at first upright then spreads out a little. Remove leaves from deciduous plants that collect in the rosette in autumn- they blow in from god knows where and leaving them can encourage rot. Excellent in containers. Move containerized plants under an eave or overhang to keep it dry in winter. No water required after initial establishment. Beautiful form of this cold hardy species. High deer resistance.
Agave parryi ssp. neomexicana
New Mexico Agave is a spike wonder. Much more upright-growing than the species with sharp-tipped leaves that terminate in a blood red thorn. OW. Forms a very symmetrical plant with many leaves of steel blue. Full sun and VERY WELL-DRAINED soil. Excellent on hot slopes where it will tilt the rosette to avoid winter wet. Pups, heh, freely and you will soon have many rosettes. Amend the soil with pumice and gravel. Make sure there is plenty of air in the soil and no place where water could collect. Fantastic specimen plant for a dry garden/gravel garden. Water through the first summer to establish then none in subsequent years. Clean out the rosette when deciduous leaves collect in there- a shop vac works great. The leaves will cause rot when they decompose….so they must go. Great in containers- large, sturdy containers. Cold hardy. High deer resistance.
Agave parryi ssp. truncata
Consistently one of the most successful Agaves for gardens in our region. Soft gray rosettes have leaves with a distinct upright habit. At the tips of the wide leaves is a single (deadly) black thorn. Very nice. Full sun and very well drained soil with little to no summer water when established. This Agave requires soil that is never soggy- amend heavily with pumice and gravel to create air pockets. Plant this (and all) hardy Agaves in our climate on a tilt. The tilted rosette sheds rainwater and it keeps it much drier in winter. Ideally, this Agave should be sited on a hot, south facing slope. In autumn deciduous leaves from (everywhere) seem to blow into the rosette and collect. You must remove these immediately so that they do not rot the center of the plant. A shop vac works wonders…so do bar-B-Q tongs. Excellent in containers. Its best to plant hardy Agaves in early spring to early summer. They require a long season to develop a root system which ensures that they are cold hardy. No root system and not so hardy. Hardy below 0ºF when dry. Highly deer resistant.
Allium acuminatum
This delightful onion has a wide range in our state. Primarily you see it in dry, exposed sites a little way up from the bottom of the Willamette Valley. Mid green slightly fragrant grassy leaves give way to an 8″ stems in May-June with a chalice of multiple pink/lavender pink upward facing flowers. Full sun to part shade and adaptable to many soils as long as there is a dry rest in summer. This onion quickly goes summer dormant directly after seed set and disappears entirely by mid summer. Great pollinator bulb for Willamette Valley meadows. Its nearly always on a slope where it is found. Replicate this and give it only the rain that falls from the sky in subsequent years. In time the bulb multiplies and it can also self sow. Leave a disturbed area around the plant and keep it free of weeds and they can mature and bloom in several years. Light deer resistance. aka Slender leaved onion. Very attractive food source for butterflies. Oregon native plant.
Allium sikkimense
Blue is an elusive color in Alliums but there are several that achieve that hue. This small bunch forming onion is a delight with clusters of nodding blue flower in mid-late summer. To 10″ tall a multiplying clump will spread to 1′ wide over time. Rich, well drained soil with regular summer water. Excellent in rock gardens, the front of borders and even hellstrips. Very easy to grow herbaceous perennial that blooms for 4-6 weeks. Cute little cutflower and loved by pollinators. Winter decidiuous for full sun- no fudging here. Long lived and hardy in containers. Moderate deer resistance.
Amsonia hubrichtii
Threadleaf Bluestar is a fantastic native North American perennial with many seasons of interest. To 4′ tall this strongly clump-forming perennial has thread-like green leaves that line the sturdy, very vertical stems. Upon rising in late spring they host clusters of star shaped, fragrant (yep) blue flowers. Very pretty. The green, fine-textured foliage holds space as a blowsy presence in borders, gravel gardens, hellstrips. In autumn the entire plant turns shocking yellow and stays that way for weeks. Fall color at ground level and it rocks. Light but consistent summer water to aid in establishment. Very drought tolerant then. Full sun in any soil type but for permanently boggy. Good deer resistance. They will try it once but not again- for what it’s worth. Completely deciduous in winter. Emerges mid-spring. Very long lived, no-fuss perennial. Mix with ornamental grasses, cacti, just about anything.
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.
Anemanthele lessoniana
Pheasant Tail Grass is a clumping large arching grass with colorful surprises throughout the year. To 30″ tall and a little wider the army green arching foliage takes on dramatic orange and red tints if given just a little stress. In summer fine tawny orange/brown glossy seedheads arch gracefully within the foliage. Full sun to very light shade in rich, well drained soil with consistent summer moisture- a little dryness and wham! You get those fiery tints. Requires a protected location in gardens, avoid full on exposure and cold winds. Its best application though is as a large graceful container subject. And the drainage adds to cold hardiness. Remove seedheads before they mature as it does like to seed around. Mulch for arctic weather. Moderate deer resistance. New Zealand.
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.
Apocynum androsaemifolium
Spreading Dogbane is a pretty semi-shrubby native perennial that is found in every biome in our area. David Douglas mentioned this billowing perennial with clouds of light pink/white bells. Mostly he hated tripping over it in the Willamette Valley. This very permanent plant spreads to form big drifts in the wild. Streambanks, prairies, alpine meadows it can appear. The rounded downward pointing leaves emerge on semi-woody stems. In June-August clouds of flowers appear for weeks. Loved by pollinators and birds specifically attractive to native hummingbirds and butterflies. To 2′ tall and spreading by stolons to a wide area. Water to establish then none in subsequent years. Mulch after planting. Virtually any somewhat rich soil type including amended sand. Full sun to part shade. Wonderful plant and floral texture for meadows. I have great childhood memories of this plant in July in full bloom perched with our huge native black bumble bees. Very convenient bloom time- it begins to bloom just as most other natives are finished. Dogbane is toxic when consumed by humans or animals- hence the common name. When stems are broken a milky sap is exuded. Moderate deer resistance. Distantly related to milkweed. Once very common in the Willamette Valley its territory has shrunk. Great performance in hellstrips and verges that are lightly or completely non-irrigated. Give this plant room to spread and plan ahead. Limited availability. Oregon native plant
Aquilegia chaplinii
Native to the Guadalupe Mountains of New Mexico and extreme west Texas this adorable columbine enchants us with its whimsical soft yellow flowers and fine blue foliage. To 18″ tall in bloom the petite flowers have long fantastic tails. They appear from April-June, and occasionally again if you remove spent flowers and prevent seed set. This smaller plant has wonderful finely divided blue green foliage that forms a fountain before and after bloom. Often self sows in open sites. The original plants live about 5 years but the distinctive leaves will give away the seedlings. They seem to favor cracks in pavement, stones. Full sun to very light shade in rich to average soil with regular summer water. Mix with our native Columbine (Aquilegia formosa) for a color echo on the yellow perianth of both. Very popular with pollinators including native pollinators. Winter deciduous. Moderate deer resistance. Charming and easy to grow wild flower.
Arctostaphylos edmundsii ‘Witches Broom’
A very compact and slow growing form of this species.. Round glossy leaves add to the the overall dome shape. In winter into spring a continual procession of whitish-pink flowers. They come in groups and decorate this small shrub evenly. 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.
Arctostaphylos silvicola ‘Ghostly’
Ghostly white fur covered foliage is almost too pale to believed and ‘Ghostly’ is an apt name. A distinctive Manzanita to 8’ tall and 4’ wide in 5 years. Fast growing in our climate. Do not be afraid to cut back lanky new growth for a more upright and sturdier plant. Tends to send out a lot of vertical stems, those may be cut to initiate denser branching. Prune in July. In late winter and early spring clusters of white urn shaped flowers appear at the branch tips and delight hummingbirds. There is no more silver/white foliaged Manzania that we have seen. Truly spectacular in well drained soil with good air circulation and little summer water once established. From a species native to the Santa Cruz Mtns. in California and surprisingly cold hardy.
Artemesia versicolor ‘Seafoam’
Lovely, soft gray curls make up the foliage of this low spreading perennial. Easy to grow and long lived plant for full sun and well drained soil. Little summer water when established. Takes the hottest aspects with aplomb and remains good looking all season. At the end of summer stems extend to produce small white flowers. Not really showy but it expands the overall texture of the plant. Completely winter deciduous. Cut back hard in early spring. Forms woody stems at the base and is a quite permanent plant. Flows in and around other plants gracefully. Moderate deer resistance. To 1′ x 3′ in a season.
Many learn this plant as Douglas Mugwort but its more official common name is Douglas Sagewort. This aromatic vigorous perennial is common throughout western Oregon. It happily inhabits everywhere from ditches to the headlands at the beach. The plant has medicinal qualities that were used by native Americans and they also used the pungent smoke to ward off the spirits of the dead. To 3′ tall and spreading underground by rhizomes. This is a very vigorous plant when established, give it room and the respect it requires. In improved situations it can swamp other plants so best to leave your patch of sagewort to its own devices. Mix with other plants of similar vigor- Spiraea x pyramidata or Rosa nutkana. Give it at least 5′ x 5′ feet to roam. In summer plumes of off-white flowers produce a haven for pollinators. This member of the daisy family brings them from long distances. Very long lived deciduous perennial with long indented leaves that are dark green on top with an underside of pure silver. This makes this almost woody perennial very easy to spot in breezy conditions It appreciates average soil and light water to establish.. If it flags in drought you may give it a deep drink in summer to refresh. Loved by a host of butterflies. Doesn’t need much love to perform. Oregon native plant.
Asclepias fascicularis
Narrow leaved milkweed is an Oregonian butterfly weed that has a great wildflower demeanor and is just as attractive to pollinators as well as Lepidoptera (butterflies). Full sun and well drained soil, though it accepts clay soil on slopes that are strictly unwatered in summer , otherwise light consistent irrigation to establish- then natural rainfall alone. To 22″ tall and making a spreading plant. Mix with fine textured ornamental grasses,such as Tufted fairy grass – Deschampsia caespitosa and tall spiky perennials such as simultaneously blooming Kniphofias. Light summer water when companion planted. Flower color is most often creamy white but ranges to light pink. Often seen on road cuts and in ditches in the Willamette Valley. Blends in with grasses and other plants but pollinators find it no matter what. Spreads to form colonies by underground stolons to 2′-3′ wide. Nice cutflower. Important food source for Fendler’s Blue Butterfly which is very endangered and locally indigenous. Winter deciduous. Blooms open in June and persist to August. The large seed heads are pointed and release their downy seeds on the wind in August-September. Oregon native plant.
Asclepias speciosa
This widespread species is native to the floor of the Willamette Valley and is locally common in the Columbia Gorge where it occupies dry rocky hillsides in full sun but tolerates heavy clay soil. In the best conditions (loam) it is huge spreading perennial that requires pre-planning and some real estate. Gray green stalks and leaves rise up to about 4’tall and bear deliciously fragrant pink orbicular flowers. These are irresistible to butterflies, including Monarchs, and if you want one to visit your garden this plant is good insurance. However, all butterflies find it irresistible. Spreads underground vigorously by stolons and can come up quite a way from the initial clump. Full sun and well drained soil. Completely winter deciduous and emerges relatively late in spring. Be patient. see video below. IMG 6323. Oregon native plant.
Asclepias tuberosa
Common butterfly weed native to the central parts of the continent makes a striking long blooming perennial in our gardens. To 2′ tall flat cymes of brilliant orange flowers appear in July and re-bloom until frost. Emerges late – not until May and then rockets out of the ground and almost immediately commences blooming. Fantastic plant for all pollinators. Remarkably showy perennial for very well drained soil- try a slope and deep but infrequent irrigation or add a few handfuls of pumice to the planting hole. Mine thrives in the heat and rigors of my hellstrip. completely deciduous in winter.- its good to remember where you planted it. Butterflies, Oh the god damned butterflies. Excellent combined with blue and purple flowered perennials such as Verbena rigida with the same cultural requirements and bloom time.
Asphodeline lutea
You don’t see this perennial from the middle east very often in our gardens. Its a great, low water long lived plant with dramatic, showy flowers. Spikes to 4′ tall are clouds of large starry yellow fragrant flowers. Blooms appear in May and June and are showy for weeks. Grassy blue green leaves form a clump at the base. Rich, well drained soil with little to no summer water once established. Mass for a very showy effect. Remove spent flowers and you are left with relatively good looking low arching blue green leaves. Must have full sun and a bit of patience to bloom. We try to sell them in bloom to avoid the wait. Moderate deer resistance. Winter deciduous. Long lived.
Athyrium x ‘Ghost’
A hybrid fern discovred in Oregon and it has become a garden staple. Soft gray/sage green intricately divided fronds arch out from a central rosette. To 2′ tall and as wide in rich, well drained moisture retentive soil in part shade to shade. Loves regular irrigation and bulks up more quickly then. More adaptable than its harder to grow parent Japanese painted fern. Completely deciduous in winter. Takes poorly drained sites. Mix with chartreuse leaved Lamium maculatum ‘Aureum’ and Vancouveria chyrsantha for wonderful woodland trio. Emerges in March- not bothered by snails/slugs or deer. Excellent in shady, perennial containers. Good appearance thought hot summers with irrigation. A classic.
Baeckea gunniana
Heathmyrtle as it is known is a fine textured shrub that closely mimics Erica (Heath) and is an aromatic member of the Myrtle family- Hence the common name. The fine needle leaves emit a powerfully sweet menthol perfume when bruised. In winter the entire arching dense shrub takes on vivid copper tints. Early summer brings boughs spangled in tiny white flowers like frost. To 3′ tall and 4′ wide in 5 years in rich, well drained soil with light consistent summer water. Pairs perfectly with Heaths and Heathers with identical cultural requirements. Strong deer resistance. Cold hardy to 5ºF or below. Wonderful evergreen shrub. A Xera favorite. High mountains of Tasmania. It would make a fine sheared hedge. Any amount of pruning results in a much denser plant. Plant on three foot centers. Underused wonderful shrub.
Beesia deltophylla
Still relatively new this extraordinary perennial has so many fantastic attributes it will become indispensable in our gardens. Glossy concave heart shaped leaves emerge tinted black before settling to a deep forest green. The dense foliage is seldom bothered by pests and appears to be slug/snail resistant. Throughout the growing season 2′ spikes emerge over the dome of dense foilage with small white flowers. The over effect is cool sophistication in the shade garden. Slowly expanding to 2′ wide. Rich, moisture retentive soil with regular summer irrigation. Mix with Hosta, Hakenochloa, Epimedium. Semi-evergreen.
Berberis darwinii
Darwin’s Barberry is probably one of the showiest barberries in bloom and has excellent performance in Western Oregon. Deep green, glossy, prickily small leaves clothe the frame of this dense and arching shrub. In March/April the whole plant is alight in chains of vivid orange/yellow pendant small flowers. They come in such abundance as to obscure the foliage. By summer those that found a pollinator transform into blue berries covered in a light powdery bloom. Full sun to very light shade in virtually any soil that does not experience standing water. This Chilean native loves our similar maritime climate and is supremely tolerant of summer drought as well. Typically grows to 4′ x 6′ moderately fast. High deer resistance. Locate out of the path of subfreezing wind (east wind) in Portland as it can burn the foliage in severe arctic events. Recovers quickly. No longer recommended for the Oregon Coast. It has been recorded as escaped in several coastal counties. Inland colder temperatures mitigate invasiveness.
Berberis x lologensis
Very cool, rare evergreen barberry hybrid that is naturally occurring in the far southern Andes of Chile/Argentina. Apparently where B. darwinii and B. linearis grow together you can get this lovely huge evergreen flowering shrub. In early spring the arching stems are lined with pendant flowers that arrive as bright red buds and open to hot orange- both colors are present on the flowers which have the fragrance up close of coconut oil. Large growing arching shrub with kind of a wonky habit. Site it where you can spot the vivid flowers in March and then let this spiny creature fade into the background for the rest of the year. Completely drought adapted but will also take regular water. Virtually any soil apart from standing water. Perfectly hardy to cold. High deer resistance. Very difficult to propagate so we only have this fast growing handsome shrub on occasion. But no one else grows it so we list it. Long lived.
Blechnum penna-marina (Austroblechnum penna-marina)
Antarctic Water Fern is a low creeping evergreen ground cover fern for moist shady sites. To just 5″ tall the new fronds emerge a bright red before settling to soft green. The pointed finely divided leaves overlap densely creating a cover that blocks weeds. Slowly expands up to 3′-4′ wide when really happy. Rich, moisture retentive soil with regular summer water. Avoid compacted dry clay- does not like. Easy to grow in woodlands, Excellent performance under large shrubs. Avoid hot sun. Good small scale shady ground cover. High deer resistance. Chile.
Blechnum spicant (Struthiopteris spicant)
The second most common fern in western Oregon Deer fern is a lovely native evergreen clumping perennial that is invaluable. The tiered upright and then settling to horizontal mid green glossy fronds are handsome all the time. To 2′ wide and 2′ tall (when fronds are emerging). Rich, moisture retentive soil high in organic matter. Light summer water in part shade to shade. Familiar fern of the Oregon Cascades but very widespread. High deer resistance. Excellent native fern for life between Rhododendrons and Pieris that are ancient. This fern loves part shade and cool moist soils but has a bit of drought adaptation as well. Its supremely adapted to to the rough life of competition. Useful plant that looks very good year round. Design by Vanessa Gardner Nagel Seasons Design. Oregon native plant.
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.
Boorinda angustissima
Little leaf CLUMPING Bamboo has risen to the top as one of our favorite Bamboos. Rapid growing with culms shooting quickly to 10′ tall, they then become clad in masses of tiny mid-green leaves as the culms begin to leaf they slowly sink down. The effect is a a wide spreading fountain. The clump increases painfully slow though and the 1/2″ culms crowd together at the base. Part shade to shade in any well drained soil. Extremely drought adapted for a bamboo. Though it does not run you must give it a wide berth to arch. Amazing texture of green fountains. Culms are purple upon expanding. Light summer water. Protect from reflected heat of hot walls. Takes pruning exceedingly well. Responds almost immediately as a denser plant. It appears best to prune once the culm has completely unfurled. Then head back the culm from the top. If you against pruning it sounds brutal but it actually looks quite natural and does not really diminish the plants grace.
Brachyglottis greyi
Excellent grey leaved evergreen low shrub for hot and sunny sites. To 3′ x 4′. Foliage is grey on the top of the rounded leaves with a distinct white undersides. In summer clusters of brilliant yellow daisies are showy and provide excellent contrast. Best in poor to average well drained soils – accepts clay soils with little summer water. Very drought tolerant. Best in the mildest gardens. Dry hillsides, shrub borders, hot aspects. Little to light summer water. Good deer resistance. Cold hardy to about 10ºF or a little lower if soil is strictly un-amended and summer water is sparse- neglect leads to a hardier plant in the long run. New Zealand. Excellent performance at the Oregon Coast. Don’t be afraid to cut back this shrub after blooming has ending. Cut several inches into existing branches this will form a dense upright plant with more foliage and a tidier habit. Very good urban shrub.
Brachyglottis monroi
Fun small shrub that we love for its wavy (undulate) gray foliage and compact habit. Evergreen shrub to 3′ x 3′ moderately fast. In summer it is topped by clusters of electric yellow daisies- nice contrast with the gray foliage. Full sun and well drained soil with light to little summer water once established. Avoid exposure to subfreezing east winds- site on a south or west facing aspect if you are in the wind zone. Excellent performance on hot dry slopes. Moderate deer resistance. Great at the Oregon Coast. Evergreen. New Zealand.
Buddleia loricata
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.
Bupleurum fruticosum
A subtle but very sophisticated hardy evergreen shrub that is found in all the best gardens. Shiny sea-green leaves are reminiscent of a Euphorbia and are handsome year round. In summer long stems sport umbels of chartreuse green flowers gives away its familial affinity to Dill. Tough shrub that is adaptable to all but boggy soils. To 6’ tall and as wide in several years. Blooms on new wood, may be hard pruned in early spring nearly to the ground to refresh and resize. Re-growth is rapid. Equally tolerant of drought and regular irrigation. A great plant that instantly makes a planting look sophisticated. Excellent with Lavenders and Russian sage. An irresistible pollinator plant that will be covered in multitudes of insects while in bloom. Very easy to grow. Water weekly until firmly established.
Buxus sempervirens ‘Graham Blandy’
Hard to find but so useful columnar boxwood. Graham becomes a 10″ wide pillar up to 6′ tall or taller within a decade. Very easy to keep it much smaller. Prune reliably to retain a tidy demeanor. Deep green foliage is thick and handsome year round. Average soil, light summer water. Full sun to full shade- no difference in performance. Very cold hardy. Grows 6″ a year.
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.
Caesalpinia gilliesii (Erythrostemon gilliesii)
Bird of Paradise shrub is an incredibly showy flowering plant that is surprisingly adaptable to the Willamette Valley. Native to Argentina/ Uruguay the exotic large yellow flowers in whorls each with 3″ strings of blood red stamens protruding. Each flower lasts but a day but a truss carries many individual flowers. Fine divided foliage is light gray green and a great foil for the exotic flowers. Full hot, all day sun in a hot site. Ideally, it should be located against a south facing wall- this heat lover is slow to break dormancy in spring and doesn’t normally begin flowering until mid-summer and continuing until cool weather. To 8′ x 8′ drought adapted but water speeds growth. Deciduous. Spectacular. Non-blooming youngsters may need a year or two in the ground to commence blooming heavily. Patience is all that is required. This shrub loves the hottest spot in the garden. Pick a place that would be unbearable on a hot day and you’ve found the home for this sun lover. Bipinnate leaves close with darkness. Each flower opens for just one day but a procession of buds releases them over a period of many weeks. Blooms on new wood, growth from the current season.
Calamagrostis foliosa
Mendocino Reed grass is a regal plant from the northern California coast. Well scaled for gardens a 1′ x 2′ wide clump eventually forms with stiff, tidy blue green arching leaves that are blue with purple highlights. In spring to mid-summer 1′ tall spikes of flowers that begin russet and age to soft tan appear and are immensely showy and symmetrical. A back lit plant in bloom is a festival of brilliant tones. Best in light shade and average to rich, well drained soil with light summer water to improve vigor and appearance. A cool season grass that looks wonderful in winter as well as summer. Excellent garden plant that has proven to be easy and adaptable, Unfortunately, it can be hard to propagate and availability is spotty. Evergreen.

Wow- one of the best perennials that we grow. Easy to grow, so useful, pretty and even a nice edible that we enjoy in summer iced teas. A dome shaped perennial that is virtually everblooming. Clouds of tiny white flowers are absolutely LOVED by pollinators of every kind. A well grown clump in bloom is a buzzing fountain of activity. Blooms May to September unabated. Full sun, rich to average well drained soil with light but consistent summer irrigation. The fine white clouds of flowers work well as filler in borders or as a low cloud supporting taller flowers. Winter deciduous. Loved by the kitties. To 2′ tall and 2′ wide in a single season. Cold hardy and low water. Exceptional plant. See video below. No other plant we grow is as popular with pollinators as this. Takes a second for the video to load.
Callistemon (Melaleuca) ‘Woodlander’s Hardy Red’
This has become the standard cold hardy red flowering bottlebrush in our climate. 4″ brushes of raspberry red occur en mass in May/June and sporadically there after on established plants. Low, spreading arching habit. Give it horizontal space to grow. Virtually any soil type and incredibly drought adapted when established. Accepts regular irrigation as well. Must have full, all day sun to perform. Avoid exposure to subfreezing east winds, err on the side of protection. Cold hardy to a little below 10ºF but has vigorously recovered from subzero lows returning from the base. If damaged by cold cut back in spring- then supply regular irrigation and recovery is rapid. Moderate deer resistance. To 3′ x 5′ wide in 6 years.
Callistemon (Melaleuca) (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.
Callistemon (Melaleuca) 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.
Xera Plants Introduction
Callistemon (Melaleuca) 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.
Callistemon (Melaleuca) pityoides ‘Mt. Kosckuisko’
Dwarf alpine Bottlebrush that we like most as a clipped hedge. Dense rounded shrub composed of fine olive green needles. To 3′ x 3′ in time. Full sun and very little water when established. It can also tolerate regular summer irrigation. Sporadically, in late spring starry cream colored bottlebrush flowers appear. Extremely hardy to cold and very deer resistant evergreen. Alpine Australia. This durable shrub with a fine texture makes a fantastic clipped hedge. It can be trained as one solid shrub or separated into spheres. Pruning is done just once a year in early summer. This can sacrifice blooms but the effect is striking for a small cold hardy, drought tolerant, low prune hedge. In time it blooms more heavily. Give it a few years. The starry white stamens are tipped in yellow for a light yellow overall color. Highly deer resistant shrub. Great year round appearance.
Callistemon (Melaleuca) pityoides ‘Wetland’s Challenged Mutant’
A great introduction from the Sequim, WA nursery Desert Northwest. Incredibly showy in bloom this easy to grow shrub produces 4″ long 1″ thick soft yellow colored sweetly scented brushes in late spring and early summer. Moderately fast growing shrub to 7′ tall and 3′ wide in 6 years. The pretty, fine foliage is handsome ochre green and contrasts beautifully with the light taupe colored bark.This is an exceptional shrub out of bloom as well and has a very upright, tidy habit for this genus. From a distance a mature shrub appears like a Podocarpus. Full sun and average to rich soil with light but consistent summer water. Drought adapted. Considering the size of the brushes this is an exceptionally hardy Callistemon taking 5ºF when established. If there is any confusion about which species this appears to be- the foliage is unlike C. pityoides but the large brushes are dense and fragrant just like that species. A hybrid is likely. This very upright shrub would make a fantastic informal hedge/screen with minimal pruning. Great shrub. Pollinated at night by moths who will literally glue themselves to the brushes for hours. Fascinating shrub.
Callistemon (Melaleuca) pityoides ‘Corvallis’
I found this Callistemon in a garden in Corvallis, OR over 20 years ago. For the previous 30 years it had thrived through the coldest (0ºF or -18ºc) winters. Upright growing fine textured evergreen shrub to 6′ tall and 3′ wide in 7 years. 2″ pale yellow fluffy brushes appear in late spring/summer and again in early autumn. Full sun, average soil – especially good in clay soils and regular summer water- though it can live on no supplemental water in summer irrigation improves fall bloom. Completely deer resistant. Perfectly hardy in all of Western Oregon. Long lived shrub that tolerates heavy snow and ice. Easy shrub. Moderately fast growing. Excellent performance on the Oregon coast. Prune if needed after bloom has ended. Excellent companion shrubs are Ceanothus x ‘Topaz’ and Myrtus communis ‘Andy’s Hardy’ which bloom simultaneously,
Xera Plants Introduction.
Callistemon (Melaleuca) subulatus ‘Dark Red’
There are several hardy red flowered bottlebrushes on the market but if you really like red this is the one. Small gray thin leaves densely clothe the arching stems of this clumping multi branched low shrub. In spring and then sporadically all summer deep red 2″ long and wide bottlebrush flowers appear. Happiness and hummingbirds ensue. To 3′ x 3′ in 5 years and strongly arching. Full sun and a protected location- against a south or west facing wall is ideal. Light summer water.

Common variegated sedge that is useful. The arching thin leaves have an interior of rich yellow with green lines on the sides. Dense forming evergreen tuft to 1′ tall by up to 2′ wide. Rich, moisture retentive soil with regular water in full sun to part shade. Tidy discolored leaves individually in spring- do not cut to the ground. It hates this. Gold stems support tan flowers in summer. Unfortunately, this sedge is often thrown into new landscapes and is marketed as a low maintenance carefree drought tolerant thing. Its not. It likes good care to look its best. Moderate deer resistance. Evergreen.
Carex pansa
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.
Carex tenuiculmis
We playfully refer to this large sedge as rootbeer grass. Its that color of ochre brown and it shine on this plant all year. One of the hardiest and longest lived New Zealand sedges for full sun, well drained soil and light consistent summer water. To 14″ tall but spreading up to 3′ across. Trailing stems hold little brown flowers in summer. Very good winter appearance and it has survived temperatures below 10ºF with good drainage and full sun. Elegant trailing down a hillside. Very good in large containers including winter containers. Easy to grow. Moderate deer resistance. Give it room to spread.
Carpenteria californica
Bush Anemone is a locally rare native of the Sierra Nevada foothills in Fresno County in central California. This tough evergreen shrub with thin deep green leaves set against pale exfoliating glossy bark is perfectly hardy to cold and drought. In May/June 3″ wide pure white flowers with a central yellow boss of stamens are sweetly fragrant. Full sun to almost full shade in any soil with adequate drainage. Adaptable to dry clay soils and able to endure extreme drought. Extraordinarily climate adapted- enduring summer drought and winter rain. Appreciates good air circulation. No crowding. To 8′ tall and 5′ wide in 6 years. Often left alone by deer- but they will definitely try newly installed plants. One of our most treasured west coast native shrubs. Very long lived sited correctly and denied summer water. Accepts blasting reflected heat. In time you can limb up the shrub to reveal the white/taupe exfoliating bark which appears glossy with age- this also assists in the air flow that this shrub craves. A monotypic genus. There’s just one species. Limited quantities.
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.
Catananche caerulea
Cupid’s Dart is a simple to grow and wonderful perennial that blooms non-stop all summer long. The papery blue flowers with a deeper blue center attract all kinds of pollinators and are a specialty of Butterflies. Clump forming plant with tall wand like stems that support the flat flowers. Remove spent flowers to encourage more. Full sun and a host of soils that are sharply drained. Regular summer water though it makes due with dry conditions when established. Highly deer resistant. Wonderful companion for roses and perfect with Lavenders for a long blooming light textured wave of flowers. Each flower closes tightly at night. To 20″ x 20″ forming substantial clumps.
Ceanothus ‘Blue Jeans’
One of the cold hardiest blue flowered cultivars and one of the earliest to bloom as well. An open spreading shrub with prickily deep green leaves. In March/April the whole shrub is obscured in violet blue clouds of flowers. Upon first viewing in bloom most people are shocked at how showy this evergreen shrub is. To 7′ x 5′ in five years in any well drained soil with little to no summer water. Very adaptable to clay soils, especially on slopes- as with all Ceanothus avoid boggy sites. One of the toughest cultivars that also takes very well to pruning which should be done after blooming to increase density if needed. Blooms on wood from the previous year and the button shaped flower clusters are so profuse that they obscure the foliage. Tolerates blasting reflected heat and is great in hot urban situations. Makes a wonderful informal hedge for wild areas but is just as at home clipped into urban scenes. Full sun. Moderately deer resistant- unusual for a Ceanothus. Cold hardy to 0ºF. The cultivar name might obliquely refer to the flower color but its an apt comparison to this tough , tough, shrub as well. No summer water. See clipped hedge below.
Ceanothus cuneatus ssp. cuneatus ‘Adair Villiage’
This is a Willamette Valley native form of Buckbrush found in the SW part of the Valley. This species is found historically from the Portland/Oregon City area in the Willamette Valley and throughout the southern half of the state well into California.Small isolated populations occur in central Washington- revealing a much larger range at some point. It has lost large areas of its northernmost natural range to development and fire suppression. It is a fire adapted species that requires disturbance to distribute. Thats a pity because this is a fantastic native shrub for hot dry sites. It is now employed by ODOT for freeway plantings and we are happy to see that. A large, angular evergreen shrub with small deep green paddle shaped leaves. In April the whole shrub is swarmed with pure white flowers.This is a beacon to all pollinators and the sweetly fragrant flowers will literally be buzzing in bloom. Fast growing incredibly tough shrub for areas of intense drought and reflected heat. To 8′ x 8′ very quickly in any soil that does not become boggy. Excellent performance in tough urban situations. Irresistible to bees and butterflies. Associated plants in the wild are Rubus ursinus, Dodecatheon hendersonii, Iris tenax and Ranunculus occidentalis. Extremely cold hardy to below 0ºF. No summer water. Moderate deer resistance. Oregon native plant.
Ceanothus gloriosus ‘Pt. Reyes’
The most popular ground cover Ceanothus and an important plant in our climate. Evergreen ground cover shrub that covers the ground densely. In March the entire plant is smothered in light violet blue flowers. Stems root where they touch the ground making it a valuable erosion control. Full sun to light shade in any well drained soil. Excels on steep slopes. To 10″ tall and 3′ wide very quickly. Plant on 3′ centers for a fast dense ground cover. If the shrub grown as a ground cover gets too tall it may be sheared after bloom has ended. Water to establish for the first season, this also speeds growth. Excellent performance in Hellstrips. Little water once established. Moderate deer resistance.Avoid direct exposure to subfreezing east wind. Very well adapted to the Oregon coast.
Ceratostigma willmottianum ‘Xera Sky’
A cool sub shrub that covers itself for months in dime sized sky blue flowers. The intensity of the color is hard to capture- it must be experienced. Forms a rounded wiry shrub with diamond shaped wavy small green leaves. To 2′ x 2′ in a season. Full sun, and rich, well drained soil with regular summer water. Freezes to the ground below about 15ºF- re-sprouts form the base in spring. Great in containers. The better the drainage the hardier this extraordinary plant will be. Provide a warm position and mulch in autumn. Once it has been established through a winter it is a fairly permanent plant. Some deer resistance. Do not cut back until you see new growth in spring- then remove all damaged stems. Great in hot sunny borders. Regular summer water.

Mixes very well with Arctostaphylos as well as Ceanothus. A really great rock rose. Tp 3′ x 3′ in 5 years.
Cistus x bornetianus ‘Jester’
We’ve grown a LOT of pink flowered rockrose. This is our favorite by far. The large flowers are clear pink on the edges fading to near white around the boisterous orange/yellow center. This gives each cupped flower a luminous backlit effect. It blooms profusely and the elegant but subtle flower color virtually marries its gray leaved backdrop. Excellent. To 3′ x 4′ in 5 years ‘Jester’ exhibits great cold tolerance as well as drought adaptation. Full sun and well drained soil with little summer water once established. The large (3″) Pink flowers appear for 4-6 weeks in late spring. Fragrant foliage is waxy and could be unpalatable to deer. Long lived for this genus. Colorful, tough plant.

Cistus x crispatus ‘Warley Rose’
A fantastic low growing Rockrose with superior pink/purple (Pinkle?) flowers for an extended period in May-July. To just 18″ tall it spreads to 3′ wide in average to enriched soil in full sun. The crinkled sage green foliage emits a sweet perfume, especially if you stick your nose right up to it- but mostly it is noticeable on warm days. Its spicy and sweet and adds to the good feelings this very cold hardy selection gives gardeners. One of the last plants to be marauded by deer it makes a great border shrub for rural areas as well. Drought adapted when established, give it one or two good soaks in summer to keep it fresh. Well scaled plant that seldom requires pruning. This selection has survived 0ºF with minor leaf burn and a full recovery by bloom time. Flowers that each last one day come in a weeks long promenade. Rock gardens, hells strips.
Cistus x pagei
Rockrose are famous for the sweet balsam fragrance emitted from their foliage. The chemical ladanum is responsible and the heart shaped thick leaves of this hybrid are drenched with it. This chemical imparts a certain amount of fire retardant. Hot days bring a wave of perfume from Cistus x pagei long after its profuse display of pale pale pink flowers. Its vaguely pink from a distance. Very heavy bloomer. To 5’x 5′ in 5 years. Exceptionally hardy to cold and very very drought tolerant as well. Tolerates subfreezing wind and temperatures near 0ºF with no harm. Excellent low care shrub for rough areas. Full sun and well drained soil. Light summer water to establish. Moderate deer resistance. Excellent shrub for rural areas. In time it develops gnarled trunks with a shredded exterior. Prune if needed AFTER flowering. Rugged, beautiful, fragrant shrub.
Claytonia sibirica
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.
Clematis cirrhosa ‘Wisley Cream’
Winter doesn’t end the Clematis season and this variety delights from November to February with masses of small cup shaped cream flowers. A very vigorous evergreen vine that prefers part shade to full sun and a large support system. To 15′ tall very quickly. Rich to average well drained soil. Visited by Anna’s hummingbirds. The delicate appearance of this vine belies its vigor. Nice looking glossy foliage. Flowers are cold hardy into the low 20’s and if open flowers are frozen more buds will be waiting for milder weather. in summer this plant goes into a kind of drought dormancy. No water is necessary, the leaves droop and may drop. This is totally normal. This winter growing vine will wake up quickly with the first cool rains. Excellent up a large tree or along a pergola. It may be pruned hard in late summer. Blooms on both old and new wood. Mediterranean.
Clerodendrum trichotomum
Glorybower. Iconic in the city of Portland this small umbrella shaped tree lines streets and populates gardens throughout the city. Late summer brings masses of white flowers held in a red calyx that perfume the area for many blocks with a sweet jasmine fragrance. Following the flowers the calyx swells to a red star and a turquoise blue berry forms. To 16′ tall moderately fast in full sun and rich soil with regular summer irrigation. Avoid disturbance around established trees which can cause it to sucker annoyingly. Large tropical leaves have the fragrance of peanut butter when bruised. Little to no fall color. Completely intolerant of shade. Do not even try. Japan.
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.
Collinsia grandiflora
Native annuals often get over looked in our gardens. They occupied vast stretches of the Willamette Valley and civilization has caused those displays to suffer. In our gardens they are precious reminders that we should include every category of native plant. Giant Blue Eyed Mary is one of our most delicate looking and stunning in floral detail, It makes a hazy cloud of beautiful blue and white small snapdragon flowers from late April to Mid June. A true annual that dies once the floral display is done. But leave the skeletons of the plant for several weeks longer to form and shed seeds for next years display. This 20″ tall grassy plant occupies open sunny sites as well as the margins of forests. In our gardens it appreciates open slightly disturbed soil. Seedlings germinate in autumn and over winter as small plants. They will heavily occupy an area about the size of a 9″ pie. Excellent plant to succeed mid and late spring bulbs. Water lightly after planting and to establish then none required. Native to the Portland city limits as well. Fantastic displays of this plant can be seen at Camassia in West Linn all through late spring. This is a very reliable re-seeder if you give it some open ground and check for slugs. Seedlings germinate quickly following the first rains and are incredibly cold hardy and drought tolerant. Don’t worry, they are from here, they know what to do. Attracts a wide variety of native pollinators including a wealth of smaller hover flies. Oregon native plant.
Convallaria majalis ‘Fernwood’s Golden Slippers’
Usually this old a fashioned species sends chills up our spines. No mind it has one of the best floral fragrances of all time its a known thug. Enter this MUCH more restrained variety with new foliage in a remarkably soft texture with gorgeous citrus/chartreuse foliage that darkens up a bit in summer. To 8″ tall and blooming in mid spring as it emerges. Fragrant! Glowing! Gorgeous! Part shade to shade with light consistent summer water. Handles clay soils with no problems. Very deer resistant.
Coptis laciniata
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.
Coreopsis tinctoria var. atkinsoniana
Columbia Coreopsis or Columbia tickseed is a locally native annual but more often biennial that is found along the Columbia River and into the gorge. Also, native throughout eastern North America. Its first season is spent as a rosette of curly, finely divided leaves that have a glossy sheen. The following early summer it erupts into groups of gold flowers, slightly reflexed petals and a red dot that surround a brown protruding cone. Loved by pollinators and they come en masse. To 22″ tall on average in bloom. For rich to average soil in full sun. The sun part is non-negotiable. Mix with native Oregon perennials and annuals such as Sidalcea virgata or Clarkia amoena var. lindleyi as well as Madia elegans for a summer long show. Very good butterfly plant. It has a scattered population in the Willamette Valley but should be grown here much more often. Self sows in open disturbed sites. Very prolific in bloom with clouds of golden flowers unobscured by pesky foliage. Nice cut flower. One stem can be an entire bouquet. light consistent summer water improves the show but this is a tough, climate adapted biennial. Reseeds itself prolifically, Moderate deer resistance. Oregon native plant.
Corokia cotoneaster
Why, its not a Cotoneaster at all, in fact Corokia is a wildly architectural shrub and evolved its twisted zigzagging stems (the official term is divaricating) and tiny leaves to fend off grazing by giant Moa birds in New Zealand. The birds are now extinct and we are left with this shrub as an evolutionary natural bonsai. To 5′ tall and 3′ wide in 7 years. Average to enriched soil. Full sun to part shade. Flowers are more profuse in sun. Regular water. Great container plant. The yellow flowers in May are often followed by red /orange berries that don’t last long. I assume the brilliant color draws birds. Established plants accept both regular irrigation as well as summer drought. Irrigation encourages growth. Left to contend with summer drought the plant is naturally smaller. Cold hardy to 5ºF or lower for brief periods. Excellent landscape or garden plant that imparts a haze on the landscape from a distance but thrills with up close views of the zig zagging branches and tiny black shovel shaped leaves. Excellent long lived container subject and will thrive even with constricted roots. We love this shrub for its silvery winter appearance in containers and in container combinations. Mix with Sasanqua Camellias and Western Blue Fescue (Festuca californica) for months long entertainment. Seldom bothered by deer.
Coronilla glauca var. valentina
Demure winter blooming shrub that produces whorls of pea shaped flowers from January to March and sporadically through the rest of the year. The divided leaves are edged in cream making a great backdrop to the soft yellow fragrant flowers. Open lax habit to 3′ tall and 4′ wide for a protected location in full sun to light shade. Great winter container plant and thrives in conservatories where it will bloom non stop. Well drained soil with light summer water. Site out of subfreezing winds- a west or south aspect.
Cotula ‘Tiffendel Gold’
Low evergreen South African ground cover with 3″ high ferny medium green foliage that densely covers the ground. Beginning in May and repeating heavily through summer wiry stems to 6″ tall are topped by petal free gold rayless disks. Little bobbles. These flowers age to a darker color giving a sea of these curious blossoms extra color depth. Cute little cutlfower that lasts. Vigorous grower that covers ground quickly in rich, well drained soil with consistent summer moisture. Avoid compacted dry soils- it will die out. Excellent weed supresssing ground cover. Good looking year round. Cold hardy to 0ºF. One 4″ pot can cover 2′ x 2′ in a season and beyond. Moderate deer resistance. Not really a whole lot here they can even get to.
Crithmum maritimum
What a cool name ‘Sea Samphire’ not sure what that means but I do know this is a beach plant on European shores. Sparse, angular and almost succulent blue foliage forms a ring of upright facing thin leaves. In late spring into summer large soft sulphur yellow umbels arrive. UMBELS UMBELS UMBELS are so in style right now. To 2′ x 2′. Full sun and average to rich well drained soil. Light to little summer water when established. Leave the Sea Samphire strictly alone. Evergreen perennial in the carrot family. Umbels. Its all about umbels. Moderate deer resistance. Edible and a fair substitute for thyme. Excellent in salads as well as cooked.
Crocosmia x crocosmiflora ‘Solfaterre’
The market is full of Crocosmia selections but we think this one is a classic. The foliage is a dramatic bronze color and the spikey leaves are a great backdrop to the apricot yellow flowers that occur in July to September. To 2.5′ tall and forming an expanding clump. Full sun to part shade in rich, moisture retentive soil with light but consistent summer water. It makes a very good cut flower that lasts in a vase. Combine with other sun loving late summer blooming perennials. Completely deciduous in winter. 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.
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.
Cupressus macrocarpa ‘Wilma Goldcrest’
We love Wilma and have found that she’s a great landscape plant and not just relegated to seasonal containers. Fast growing dense, columnar acid green/gold tree to 9′ tall and 2′ wide in 7 years. Average, well drained soil. Do not plant this in rich amended soil, it will grow rapidly and rank and likely tip over in the first windstorm of the autumn. Instead rely on its adaptation to poorer soils to create sturdy, measured growth. You’ll thank yourself in the end. Foliage can be burned by strong subfreezing wind- plant this out of the path of east wind. It recovers quickly in spring and you’d never know there was winter burn by about May. The foliage has an intense lemon fragrance. Great in containers. Little to no summer water. Moderate deer resistance- they won’t eat it but they may rut on it.
Cupressus sempervirens ‘Swane’s Golden’
The golden form of Italian Cypress which is a very useful plant for bright vertical effects in gardens. Fast growing fastigiate tree to 18′ tall and just 18″ wide. Full sun and average to poor soil with little to no summer water. If it becomes disheveled in ice or snow simply give it a good hair cut and a denser form will emerge. You may also cut the top to limit size and a new vertical leader will quickly form. Deer resistant. Avoid overly enriched soil and shade or growth will be rank and unkempt. Grows about 2′-3′ in an average year.
Cupressus sempervirens ‘Totem’
A superior form of Italian Cypress that is thinner and more resistant to ice and snow. The foliage is forest green eschewing the blue hue of the more common ‘Glauca’. To just 10″ wide it rises to 16′ tall in a fast growing spire. Full sun (which means all parts of the columnar tree from top to bottom should receive full sunlight) and poor to average, unimproved soil. Avoid overly enriched soil which causes fast rank growth which can make the tree unsteady. Its adapted to the very poorest soils which ensure measured, sturdy growth. Our favorite form of this useful disease and pest resistant columnar tree. Cold hardy.
Cyclamen coum
Winter Cyclamen is a fantastic adaptable bulb that will form impressive colonies in time. The fabulous leaves are marked with silver and deep green designs. This form is known as the ‘Christmas Tree’ for its shape on the rounded leaves. From January to March small nodding purple/pink flowers form groups in concert with the foliage. A tonic for winter. To just 4″ tall in bloom and each corm gets bigger and bigger as years pass. Ants spread the seeds far and wide and new plants appear quite a distance a way. If you begin with a fancy leaved variety chances are most of your seedlings will mimic the parent. Part shade to shade in rich, well drained soil. Goes dormant and can tolerate completely dry conditions in summer. Excellent companion for winter Crocus, Hellebores, Snow drops.
Cyclamen hederifolium ‘Xera’s Silver’
Our seed strain of the fall blooming ivy leaved Cyclamen. After 15 years we’ve separated the best all silver leaf forms. Most have white or light pink flowers that appear from late summer through mid-autumn. In time the corms become enormous and they will seed with a large majority revealing silver or heavily silver marked leaves. Great plant for competition with dry tree roots or anywhere that is dust dry in summer. Leaves appear after blossoms and are showy all winter before going spring/summer dormant. Deer resistant. Excellently adapted to our climate. Mediterranean.
Xera Plants Introduction.
Cylindropuntia whipplei ‘White Spine’
Love this small growing Cholla that has the most amazing luminescent white spines. Densely branching low plant to 2′ tall by 3′ wide in time. Not terribly fast growing. Fast draining soils that have been amended heavily with gravel and pumice and ideally on a slope will make this a focal point in the dry garden. Light summer water will speed growth. Extremely cold hardy and not terribly fussy. Give it an open position with sun all day long. Wonderful in rock gardens. Flowers we have not seen but we assume with this species that they will be pink/purple in summer. Highly deer resistant. Great container plant. Move to a dry position in winter just for extra protection from wet.
Cynara baetica var. morrocana
Fancy and beyond showy ornamental thistle/cardoon. Finely divided silver foliage lines a stem that elongates to bear multiple large violet blue flowers. The calyx (the mechanism that holds the flower (s)) is nothing more than fiercely and lethally armed with razor sharp spikes. They will cut you . Be careful. The violet blue and lower down, pink flowers are host to every pollinator in the neighborhood, Monarch Butterflies, Hummingbirds and even the post person is drawn to this remarkable flower. To 28″ tall for full sun and rich, well drained soil. Drainage must be sharp. Light summer water. Appreciates a hot position. Moderate deer resistance. Winter deciduous. N. Africa.
Cypella (Phalocallis) coelestis
Wonderful Iris relative from South America that we cherish for its daily large three petalled intricately marked blue flowers. Rising to 2′ tall, corrugated blue green leaves accompany the strong upright stem. Beginning in May a daily procession of flowers that open at sunrise and close and finish by 2 to 3 in the afternoon. Don’t remove the spent flower as curiously more (and more) flowers will appear from the same stem. Large seed pods will form. These may be snipped off to refocus on more blooming. Full sun and rich, well drained soil in a warm position with regular summer water. I add a handful of all organic fertilizer around the base just before blooming. This markedly increases vigor and even the size of the flowers. Freezes back almost to the ground below 20ºF. Moderate deer resistance.
Cypella (Phalocallis) herbertii
Adorable little bulb that forms grassy colonies. Beginning in early summer and continuing to fall 10″ stems support amber orange intricate three petalled flowers. Each lasts just one day but new flowers appear seemingly from nowhere from the stems so do not remove- these stems can produce flowers for up to 6 weeks. Grassy medium green corrugated leaves accompany the flowers. Open sites with little competition from other plants. Sharp drainage in average to rich soil with regular summer irrigation. Full sun to light shade. Surprisingly cold hardy. Rock gardens, containers. Native to rocky plains in Argentina and Uruguay. It makes a great candidate for troughs and perennial containers where you can closely inspect the fascinating blooms. Mostly evergreen in our climate. Some deer resistance. Close iris relative.
Cyrtomium falcatum
Japanese Holly fern we love as a great fairly large evergreen. Large glossy fronds extend to 2′ long in a substantial rosette. Part shade to shade in rich, well drained soil with regular summer water. Very heat tolerant- but requires shade. Excellent container fern- great winter appearance. High deer resistance. Mass under shrubs, in woodlands for a great texture and year round good form.
Dahlia ‘Bednall’s Beauty’
We grow just a select few Dahlias now but over the decades we’ve been able to observe hardiness by cultivar. This is consistently one of the hardiest. And its a wonderful perennial. Finely divided foliage is dark, nearly black on a compact plant to 2′ x 2′ with stunning black/velvet red single flowers. These appear consistently from June to frost. Shorter stems lead to a smaller cut flower but it is still wonderful none-the-less. The intense deep flower color is a perfect match for the foliage yielding a dark tinted plant. Provide contrasting light to golden colored foliage for extra depth. Excellent border perennial for full sun and rich, well drained soil with regular summer irrigation. This hardy perennial requires very little protection other than a layer of mulch in autumn. Even a layer of leaves will provide a modicum of cover. Emerges with truly warm weather in spring. Protect emerging plants from snails/slugs. Full grown plants seem less affected. Loved by pollinators and moderately deer resistant. Far from 100% but still one of the last they will munch.
Dahlia ‘Forncett’s Furnace’
We choose the Dahlia varieties that we grow very carefully. Time has taught us that all Dahlia cultivars do not share the same cold hardiness. What we’ve whittled down is a list of Dahlias that have never frozen away for us. This marvelous selection boasts large single firey orange flowers on tall waving stems. The intensity of the flower color is shocking and it make a great denouement to summer blooming well into autumn. To 5′ tall in the ground this robust perennial requires some protection as it first emerges to deter slugs/snails. Once its up and growing fast this is less of an issue. Full sun and rich, well drained soil with regular summer irrigation. Excellent and lurid cut flower. Excellent hardiness to cold- it is not necessary to dig and store the tuber so long as the soil is well drained. Mulch in autumn post first frost adds insurance. Moderately deer resistant.
Dahlia ‘Towering Blonde’
We promised this very tall dahlia that it didn’t have to play basketball. And she agreed to produce a constant supply of amber/blonde single flowers that we love. This is a very old variety for us. In the past 20 years we’ve let our original seed and cutting raised plants dwindle as they are taken out by horrible freezes. What we’ve found is that we lose Dahlias by variety which implies two things. One, Dahlia’s cold hardiness is different for every cultivar let alone species. And (two) we’ve let nature do the selecting for us. The varieties that are left are the very cold hardiest Dahlias, and we’ve been very impressed with their performance. Rich soil that is never boggy but is moisture retentive with regular summer irrigation. Full sun and this variety also sports dark foliage which is highlighted by the lighter colored flowers. To 5′ tall with long flower stems. Dahlias as best planted in a warm full sun position in our climate where the soil seldom freezes. A thick mulch in fall is added insurance. Our varieties have been reliably hardy down to 5ºF with no issues. If you live in a colder zone you can lift and store the tubers over the winter. Replant when all danger of frost has past. Mulch annually with compost.

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.
Daphne odora var. ‘Alba’
The pure white flowered form of winter Daphne that we cherish for its large,profuse clusters of flowers that are intensely fragrant of lemon from February to April. The entire leaves are deep green and lustrous. We have decided this is the most fragrant form of winter Daphne. Dome shaped dense evergreen shrub to 3′ x 4′ for part shade to shade. Amazingly tolerant and adapted to dry shade. Avoid blasting hot afternoon sun. Great on an eastern exposure. Light water to establish. Well drained average soil but at its very best in clay soils that dry in summer- what most people have- do not amend the soil rather dig a wide hole to incorporate oxygen and allow water to percolate to the roots. Remarkably drought adapted when established. Supremely deer tolerant. Fantastic Daphne that we carry very early in the season. Reliable and heavy blooming cultivar. Exquisite.
Dasylirion wheeleri
Sotol or Desert spoon is an excellent Yucca relative that does amazingly well in our climate given the correct conditions. Native to the northern Chihuahuan Desert of northern Mexico into Arizona and stretching to the east through New Mexico into Texas is where you will find this handsome desert dweller. Rosettes of serrated blue green leaves radiate out in a circular orb. The ends of each leaf become frizzy and add an overall hazy texture to the plant. In time, when happy 9′ spikes erupt from the center and display columns of small white flowers. Very well drained soil in a full, hot position. Excellent on hot, south facing slopes but perfectly at home in the dry gravel garden. Foliage to 3′ x 3′ slowly. Evergreen. Light summer water to establish then none in subsequent years. Great in containers. High deer resistance.
Datura wrightii ‘High Altitude Form’
LOCO WEED. We discovered this native SW perennial growing very high up east of the cost of the Sierra at above 6500′. Damn it gets chilly up there. Herbaceous perennial that emerges with large, bold, silver-blue leaves. Sprawling to several feet wide in a full, hot position with exceptional drainage. All summer huge white goblet like flowers unfurl from curiously colored gray buds. You can literally watch the flowers open in the evening. They glow in the moon light and emit a soft fragrance. By 2:00 the following day the flower has withered. <sad face> but more are in the wings. Begins blooming in late June and repeats to frost. Completely deciduous (gone) in winter. Good drainage in a hot position- where the soil warms early. Spectacular. Toxic- but what garden plants are not? High deer resistance. Native to the american southwest and northwest Mexico. It has become naturalized in arts of the Willamette Valley, Columbia Gorge, and Eastern Oregon. Rarely seeds itself in our climate. The seedpods that develop following the flowers are round and spiney.

Delosperma basauticum ‘Sunfire’
Nice compact little ice plant that requires excellent drainage, full sun and regular summer irrigation. In May/June it is covered in bright yellow star shaped flowers. They open in full sun and close when its cloudy or at night. To 3″ tall and 1′ wide in a season. Best in rock garden conditions. Works well in fast draining troughs. Tiny, congested succulent foliage.
Xera Plants Introduction.
Delphinium nudicaule
Brilliant orange/red tubular flowers each with two spurs on the rear of the flower. They appear to be swarming around the green wiry stems that support them. To 20″ tall, blooms rising from a basal rosette of leaves. Blooms May-July in Portland. Somewhat tricky southern Oregon native wildflowers that needs a bit of care and correct siting to establish and become perennial. Rich, well drained soil with light but consistent summer moisture. Native to very steep slopes and cliffs with excellent drainage but with groundwater in the form of seeps near by. Wild areas, gravel gardens for the ultimate wildflower effect. Established plants will often re-bloom if spent flower spikes are removed. Hummingbirds. Moderate deer resistance. Oregon native plant.
Delphinium trolliifolium
Giant Larkspur or Cow Poison, I prefer the first common name for this stunning large growing native Delphinium. In vernally wet sites to moist upland sites it forms large spectacular colonies. In late spring and early summer stems that soar to nearly 4′ tall are loosely decorated with marine blue flowers with a lighter central bee. In habitat its common associates are Oregon Ash (Fraxinus latifolius) and Oregon white oak (Quercus garryana) where it can be found in the shade of these deciduous trees. The one variable with this Delphinium is that it is found in cool places- never hot and dry. These shadowy environs can make this plant hard to spot even in full bloom. Often they will be in standing water during the winter months and they are adapted to very heavy wet clay soils. In cultivation the need for moist conditions continues and it does appreciate at least an application of all organic fertilizer and compost at planting time. Keep it well watered through its bloom cycle, then it can go drier but never dust dry- in time it can handle much less irrigation. An annual mulch is beneficial. Wonderful, bold cut flower , but its loved by pollinators as well ( what is it about blue flowers? ). Forms spreading colonies in time. Give it room to stretch out. Its often found with our native Cow Parsnip (Hieracleum maximum) and great Camas ( Camassia leichtlinii) in habitat. This could easily be replicated in a garden. Native to the Willamette Valley into the Columbia River Gorge. Once widespread in the Willamette Valley its territory has shrunk precipitously. Long lived perennial. Very good deer resistance. Extremely showy in bloom. Oregon native plant.
Dendropanax trifidus
Underused cold hardy evergreen tree that has fascinating and handsome foliage and tolerates full sun to total shade as well as summer drought. Umbrella shaped tree with glossy large triple lobed leaves that become entire on adult foliage. Slow growing to 17′ tall and half as wide. Attractive pale tan bark. Very tough and adaptable small tree. Green flowers in summer become black berries by autumn but are almost always stripped by birds. Great branching structure and form in time. Very cold hardy and deer resistant. Flowers attract bees and beneficial wasps. Rare but stately evergreen tree. A member of the Aralia family from SW China. Moderately fast growing with supplemental summer water. Excellent small evergreen tree for courtyards.
Dianthus ‘Dainty Dame’
We love this selection of Dianthus that includes masses of white flowers with a bold maroon eye and tight handsome foliage. The incredibly fragrant flowers appear from April to frost- repeating quickly if spent flowers are removed. Good blue foliage is handsome at all times forming a dense dome. To 8″ tall for full sun and rich, well drained soil with light but consistent summer water. Great color echos can be achieved when planted in concert with purple foliaged plants. Cute, fragrant cut flower. One of the best re-blooming pinks.
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.
Dicentra cuccularia
Dutch Man’s Breetches. One of the first wildflowers that I learned mostly because of the funny common name. Native to selected spots in Oregon- in the Columbia River Gorge as well as along parts of the Clackamas River. Adorable little thing closely related to bleeding hearts. Ferny blue foliage emerges in early spring and is followed by a precious display of two spurred upside down white flowers. Each patch holds many. By the time hot weather has arrived this true spring ephemeral has disappeared completely- a good rest during the summer drought. Part shade to high overhead shade in a protected location in rich, moisture retentive soil. Occasional summer water is good- even though it is dormant. Mix with other spring delights like Erythronium (Dog tooth violets) and mid spring small bulbs like Scilla or Chionodoxa. Moderate deer resistance. Oregon native plant.
Dicentra formosa
Oregon bleeding heart is a widespread lush, long blooming perennial wildflower for moist conditions in shade to full sun. A somewhat rambunctious plant that spreads quickly by stolons. Do not plant it near shy or small plants that can become swamped. It tolerates quite a bit of shade and if in full sun it thrives with supplemental water and a massive flower display. Divided soft green foliage is very good looking, in April-July a continuous supply of rose colored downward pointing clumps of flowers on an 18″ spike. The foliage rises on average to half that height. Responds vigorously to amended soils and regular irrigation. In hot dry situations it will go quickly summer dormant. In the shade with water leaves persist to autumn and re-bloom occurs. Not bothered by pests, including deer and snails and slugs. Frequently found in shady ditches in the Willamette Valley. Winter deciduous, if not already summer drought deciduous. An easy to grow, self sufficient perennial for wild areas. Mix with other vigorous and scaled plants. Very easy to grow. Oregon native plant
Dicentra formosa var. oregana ‘Langtrees’
Excellent form of our native bleeding heart that is an incredibly long blooming perennial for gardens. Remarkable blue foliage is beautiful if it never produced 1′ spikes of clear white pendant flowers. Blooms begin in spring and with regular summer water in rich soil continue throughout summer. Shade to full sun (with regular water). Forms widely spreading colonies. Give it room to spread. This tough, adaptable plant handles any soil situation from perpetually moist to quite dry. Resistant to pests- that includes slugs and snails as well as deer. (They will briefly browse it before ditching it for better things- it recovers quickly). Completely winter deciduous. Oregon native plant.
Dierama pulcherrimum ‘Magenta Giant’
A fantastic Angel’s Fishing Rod that includes great cold hardiness and enormous 8′ wands that support hot magenta tubular flowers in early summer. Gray/blue foliage is evergreen and in this form is seldom disfigured by winter cold. Clump forming with leaves to 3′ tall and spreading slowly in rich, deep soil with regular summer water. Full, all day sun with little competition from other plants. The incredibly graceful wands arch over and dip and sway with the slightest breeze. We do this variety by division so it is not in great supply but if you’ve had Dieramas fail from cold or another reason this is the one you should grow. Do not cut back the foliage in autumn, rather cut out old and damaged leaves individually to tidy. Resents disturbance once established. By far the easiest and hardiest Angel’s Fishing Rod that we’ve grown. This is done by division so availability is limited.
Xera Plants Introduction.
Digitalis ambigua (grandiflora)
If you are a victim of deer and rabbits let me introduce you to the vast world of Foxgloves beyond the weedy bi-ennial purpurea. They are all supremely deer and pest resistant in general. This relatively long lived perennial sends up 20″ spike of the softest yellow tubular flowers. They appear in late May- July. If you remove the spent spike often more flowers will occur. This soft color – staunchly in the realm of pastel goes so well with other colors. Its a harmonious hue and this is an adaptable plant. Rich to average soil- go for rich, with regular summer water. Requires FULL SUN to bloom its best. Excellent cut flower. Winter deciduous but it returns very early in spring. Plant with Euphorbia ‘Dean’s Hybrid’ for a close tone on tone color scheme. Very pretty with Penstemon heterophyllus ‘Electric Blue’. and purple/blue Salvia cohuilensis ‘Nuevo Leon’. Very cold hardy and easy to grow.
Digitalis ferruginea ‘Gigantea’
5′ spires of condensed tubular rusty orange/brown flowers densely line the stems of this perennial foxglove in late spring into summer. From a basal rosette of corrugated mid green foliage they rise and delight pollinators and floral arrangers alike. Really cool mixed with wispy ornamental grasses. Full sun and average to rich soil with light, regular summer water. Long lived for a foxglove. I once had one persist in my garden for 15 years! Very dry adapted when established. Basal clumps increase annually and therefore so do the numbers of spikes. Supremely deer resistant as all Digitalis (we’ve expanded our offering of this genus for that very reason). Semi-evergreen. May reseed in open disturbed soils. Seedlings are easy to dispatch, move, or share with friends. AKA Rusty foxglove.
Digitalis lanata
Wooly foxglove is a vigorous and indispensable perennial for areas ravaged by deer. Native to the mountains of Greece it sends up remarkable 3′ spires with fascinating intricate flowers. Each spikes is tightly packed with small tubular flowers that have a brown/amber netting pattern on the outside. In the front of the flower a prominent white lip protrudes. The symmetrical effect of all these flowers is grand and individually reminiscent of an orchid. Part shade to full sun in rich, well drained soil with light but consistent summer water. Forms spreading rosettes to 2′ across in a short amount of time. Semi-evergreen in winter. Supremely tolerant of deer browse- they rarely even mess with this stately easy to grow perennial. Average lifespan 5+ years. The mid green handsome leaves are finely coated in white fur.
Digitalis obscura
One of our fave foxgloves, this (sub)shrubby species forms large spreading plants with multiple spikes of the most amazing flowers. 2′ spikes support tubular orange flowers with an interior of russet brown and more intricate markings. An excellent candidate for hot sunny slopes as it is native to the Iberian peninsula. Full sun, well drained soil and light summer moisture. Reseeds happily in open disturbed sites and those seedlings can be dispatched, moved, or shared with friends. Spectacular flowers appear in spring and continue into summer. High deer resistance. Average lifespan of an individual plant is 3-5 years. Dry borders, gravel gardens, exposed areas with voracious deer. Wonderful plant.
Digitalis parviflora
The so called Chocolate Foxglove gets its moniker from the soft brown tubular flowers that densely line the stalks. They tower up to 4′-5′ when happy. A perennial foxglove with amazing architectural bloom spires. That remain effective for weeks. Full sun and rich, well drained soil. Regular summer water which can often lead to re-bloom. Nice corrugated foliage lined in fine white hairs. Strong deer resistance. The textures and combinations that this offers are mind boggling. Silvery gray foliage is striking with the flower color. Also rabbit resistant. Bloom appear from April to July. Forms increasing colonies with time. A very beautiful and tough perennial. Winter deciduous.
Digitalis x ‘Honey Trumpet’
What great luck. The bees were busy in our nursery years ago and they crossed a shrubby species of Digitalis with a tetraploid herbaceous species. What we got was a fantastic incredibly long blooming and tough perennial with exquisitely honey colored flowers. Remove spent spikes in June and more will likely appear. Sterile and very likely a tetraploid. Each clumping plant creates multiple 3′ spikes of flowers- up to 15 spikes per plant! Blooms April-June and sporadically after that. Forms semi-evergreen clumps in FULL SUN and rich to average well drained soil. Wonderful in combination with Kniphofias and Tulbaghia ‘Edinburgh’. Excellent cut flower- which will spur it bloom further. Completely deer resistant. Light summer water requirements. Somewhat difficult to propagate so quantities are limited. But its worth it.
Xera Plants Introduction.
The Iris family is enormous and it features members from every continent except Antarctica. This native of higher elevations in Tasmania is a hardy species in a fairly tender genus. AKA Tasmanian Flag, this evergreen perennial forms 8″ tall narrow leaves forming a clump 1′ wide with time. In late spring to early summer a fairly long show of the most pristine white flowers. They have three prominent petals and surround a center with three tabs each marked with purple, yellow, and black.like an intricate orchid. Very light shade in average to enriched soil with light consistent summer water. The flowers rise on thin stems to 2′ and a clump with many flowers is sublime. Easy to grow- when flowering is over it leaves a clump of foliage that remains good looking year round. Good pollinator perennial. Not bothered by deer or slugs/snails or anything in general. Mulch with leaves for the first winter for added protection. This is the high elevation form of this perennial and has not been damaged in my garden down to 10ºF for the past 8 years. Rare and fun to grow. Excellent performance at the Oregon coast. Protect from subfreezing wind. Wonderful cut flower.
Dudleya brittonii
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.
Echinacea purpurea ‘Prima Donna Deep Rose’
Echinaceas have been bred, crossed and pretty much turned into mums. There is no doubt that the straight species and those closest to it are the easiest and longest lived plants. This seed strain of Echinacea purpurea displays all the best traits of the species, Large deep rose reflexed petals around an orange/brown fragrant cone. Echinacea in our climate requires regular irrigation for the first two years to establish. Its critically important in the first year. Full sun and rich soil that drains with regular irrigation. Wonderful border perennial and even cut flower. Blooms late June to late August The spent flowers may be left to feed overwintering birds, the stems turn deep black and are handsome as well. I’ve had excellent luck adding a handful of all organic fertilizer (dry) to the hole before planting. This helps the plant establish faster and in time it will require much less water. To 3′ tall and forming an enlarging clump. Moderate deer resistance. Native to the plains/midwest US. Fragrant. ( We don’t grow any double Echinacea because they are worthless to pollinators.)
Echinaceas are irresistible and this pure white flowered seed grown plant even turns it up with a soft, sweet fragrance. Echinaceas in our climate thrive but they need to have the proper beginning and soil to really work their charms. To 30″ tall and forming spreading clumps, regular water – once a week for the first year is critical. Also, I’ve had great luck amending the soil with a little gravel added to the compost that I dig in. It seems they really need a good start to perennialize and expand. In subsequent years only occasional water is necessary. Also necessary is total and complete sunshine. That seems to gird them to establish too. So, no fudging with shade. This single flowered form is pollinator magnet and you’ll find a host of native bees and bee friends visiting the flowers. It also makes a great container plant and will happily over winter no problem. ‘White Swan’ has been a Xera favorite for years. Great, long lasting cut flowers (Surprise). Long lived low care spectacular perennial. Moderate deer resistance. July to mid September. Remove spent flowers and more will often follow.
Echinacea x ‘Cheyenne Spirit’
We love this seed strain of Echinacea the least of which is that they seem to establish and over winter in a superior way. Multiple colors in these hybrids from reds to orange and yellow. large up facing flowers with a central fragrant yellow cone. Clump forming perennial for rich soil that is very well drained with consistent light irrigation in summer. Blooms naturally appear fro July to September- and occasionally longer. Remove spent flowers and more will likely appear. Great pollinator plant. Awesome cut flower. Over winters better if there is plenty of oxygen incorporated in the soil. Mulch annually with compost. Full sun to light shade. Excellent in our region on slopes.
Echinacea x ‘Green Twister’
There are SO MANY Echinaceas its hard to sort the best from the chaff. We love this unique coneflower with sophisticated flowers of pea green and pink with a central warm honey colored cone. To 2′ tall and forming expanding clumps. Rich, WELL DRAINED soil with regular H20 for the first several years. After that it seems to be much more established and requires quite a bit less. Full sun to the very lightest shade. Very groovy, fragrant cut flower and removing spent flowers will lengthen the bloom season which begins in June and sputters out in September. Echinaceas can be a little tricky to establish. What they love is the combination of rich and WELL drained soil. So, incorporate ample amounts of compost and cut it w/ a lot of pumice. Water regularly but never boggy. Butterflies adore this flower and use the blooms as a conspicuous landing pad. Leave the spent flower seeds over the winter, mine have provided food for a number of species. Seedheads turn a handsome black. Moderate deer resistance.
Echinops ritro ruthenicus
A great plant in all of its parts. Beautiful intricate large blue gray leaves with an underside of white form substantial clumps. In high summer flower spikes rise up to 3′ bearing dense sky blue orbs of flowers- the structure of the orbs gives them a metallic glint. Amazing. Obviously where it got its common name of globe thistle. Long lived herbaceous perennial for fast draining rich soils in full, hot sun. Spreads to form substantial clumps in time. Avoid sodden soils and heavy un-amended clay. Great on slopes. Completely deciduous in winter. These flowers seem to be made for butterflies- all sorts visit the flowers frequently. Light deer resistance. Plant with other large sun loving perennials to match the vigor and scale of this plant.
Echium russicum
Cold hardy member of a mostly tender genus. This native of the Ukrainian steppes sends up a 30″ spike of rose red flowers in mid summer. Excellent to include in meadows, with ornamental grasses in nearly any soil that is not boggy. Full sun. Loved by pollinators. Spike rises from a low basal rosette of leaves. Lifespan 3-5 years.. Reseeds reliably. Very light summer water.
Epilobium (Zauschneria ) ‘Solidarity Pink’
If shocking vermillion, red, and orange are a bit too vibrant for you enter this softly hued selection. Soft pink tubular flowers appear constantly from early August to October. Low spreading perennial to 8″ tall by 2′ wide in a short time. The very light green foliage is clad in soft hairs giving the whole plant a soft mien. Full sun and rich to average well drained soil is ideal. Slopes, rock gardens, walls, hellstrips all are appropriate for this low water plant. Water diligently to establish but never boggy. In subsequent years only light water on occasion is required. Spreads laterally underground by stolons. Long lived perennial if sited and somewhat cared for. Completely winter deciduous- cut away the previous years dead growth in February. Somewhat deer resistant. Mix with other late blooming perennial. Wonderful combined with Cuphea hirtella and the soft yellow flowers of Erodium chrysanthemum. West coast native plant that calls to hummingbirds far and wide. Takes blasting hot conditions in stride.
Epilobium (Zauschneria) ‘Bowman’
Possibly our second most popular California Fuchsia cultivar as it is more upright but also a free and early bloomer. To 20″ tall the fine green leaves that line the stems make the brilliant orange tubular flowers stand out. Blooms early August to October and spreading underground by stolons to form expanding colonies. To several feet wide- give it room. Rather than running over neighboring plants ‘Bowman’ flows around other plants never over topping or even crowding the. Ideal in full sun, well drained soil- or on a slope which will further assist in drainage. Brilliant flowers are a beacon to Hummingbirds. Completely drought adapted and requires little if any summer water. Long blooming western native perennial. Water regularly to establish the first year.
Epilobium (Zauschneria) ‘Carmen’s Gray’
California Fuchsia that is an excellent combination of hot orange tubular flowers set agains dusty gray foliage. To 18″ tall in bloom this Epilobium is a spreader especially in light to rich soil. Adapted to life on slopes and often between boulders on cliffs. There its roots penetrate the cool, wet cracks and that provides sustenance. Give this perennial at least 2′ x 3′ feet to roam. Wonderful performance in hell strips. Add a little compost and organic fertilizer and you’ll be off to the races. Most (Zauschnerias) require irrigation about once a month and no more than once a week to look and bloom their best. Though it is supremely drought adapted this occasional irrigation substantially improves looks. Loved by hummingbirds and bush tits too who play with the flowers and rip them apart- their goal I have no idea. Dies to the ground in winter- the only presence then is spent stems. Cut these away in early spring after a threat of a hard freeze has passed Companion plants in the wild are Diplaucus, Delphinium cardinalis, Sedum spathulifolium. California Fuchsias range into southern Oregon and technically they are native to our state. This is an excellent perennial with great contrast between the masses of hot flowers and gray foliage. Not bothered by deer. Loved by hummingbirds Oregon native plant.
Epilobium (Zauschneria) ‘Sierra Salmon’
Cool late blooming California Fuchsia with silver foliage a great foil for the soft coral and prolific September/October flowers. Spreading to 2′ wide and 1′ tall in bloom it prefers very well drained rich soil with little summer water. Full sun including hot aspects for the best results. Winter deciduous. A great flower color for the genus and pairs sweetly with autumn Salvias, such as ‘Playa Rosa’ and ‘Flower Child’. Drought adapted and cold hardy.This is the most cold hardy and drought adapted Zauschneria that we grow. It spreads and thrives on no additional summer water once established. The flowers are relatively large for this species and they are a wonderful color that meshes better than the orange/vermillion varieties. Long lived perennial.
Epilobium (Zauschneria) ‘Silver Select’
No other California Fuchsia has foliage that even approaches being as ashy white as this cultivar. Its as if the foliage is covered in dense white powder. The 1″ long hot orange/red flowers absolutely shine against this ghostly backdrop. Vigorous perennial for well drained sites and just light summer water. Full sun. To 20″ tall in bloom which starts in early August and continues into October. Hummingbirds dive down for this vivid sweet treat. Expanding to a clump 2′ wide in just a few years. Dies completely away in winter…only the stoloniferous roots remain to regenerate this sexy perennial in spring. Moderate deer resistance.
Epilobium (Zauschneria) septentrionalis ‘Select Mattole’
Our most popular hummingbird fuchsia because of its low habit, dense silvery foliage and early and extended bloom period. To just 6″ tall and spreading to form a patch 2′ wide quickly. Well drained rich soil with little summer irrigation once established. Hot vermillion orange tubular flowers are born continuously and en masse from July to October. Completely drought adapted when established. Great on slopes. Light summer water to establish. Winter deciduous. Loved by Hummingbirds. This species is native to the northern California and SW Oregon redwood region. Clumps expand stoloniferously (underground). Light summer water improves bloom in very hot locations.
Epilobium densiflorum
Spike primrose is a quiet but important long season hardy annual. It rises up to 2′ tall when happy. A dense thick spike of buds rises and the small pink flowers decorate the spike in a circle. Loved by pollinators and especially popular with butterflies. This drought adapted annual blooms from July to October. Mix with other hardy native annuals. Especially nice with Madia elegans as their bloom period are the same. Full sun in virtually any soil. Water in potted plants well and you will likely see seedlings in open disturbed sites in the spring. The seedlings of this Epilobium mimic several more weedy types (they are native but kind of rambunctious). This plant is never showy but its a primary nectar source for late in the summer. Very easy, climate adapted native hardy annual. Native in the Portland city limits. Found primarily in stable meadows on both sides of the Cascades. Oregon native plant.
Epimedium pinnatum ssp. Colchicum
We love this wide spreading and tough barrenwort. Prior to the new foliage emerging in early spring 18″ spikes arise clad in wonderful sulfur yellow almost transparent flowers. The individual flowers are large for this genus. The new growth that follows emerges amber and red before making its way to its green summer hue. Runs underground to form large stands, give it room – or at least expect this. Mostly evergreen- to be honest that foliage looks pretty beat up by spring so we advice removing it in February prior to spring growth. Part shade ( to a surprising amount of sun – if you water and are brave) in rich, deep, moisture retentive soil. Once of the most drought adapted of the genus making due with light summer water- which spurs it to spread. Ground cover under dense tree shade, dry hillsides, woodland gardens. High deer resistance. Long lived.
Epimedium wushanense ‘Spiny Leaved Form’
Beautiful barrenwort selection of an already beautiful species. Large spiny leaves with a glossy sheen begin in shades of vivid salmon red with darker mottling on new growth changing slowly to medium green by mid summer. A really good evergreen perennial that always looks its best. Evergreen leaves over winter fairly well, and if they get beaten up simply chop the leaves to the ground in February. In March, accompanying the stellar new growth tall spikes of many congest off white and pale yellow flowers seem to pour out between the new leaves. All in all its a great color coordinated perennial, dynamic and always changing. Clumps expand markedly in rich, moisture retentive woodland soil. Avoid blasting bright sun. To 2′ x 2′ shortly. Moderate deer resistance. Adapts quickly to dry shade conditions.
Epimedium x ‘Domino’
Can’t help but love the excellent performance of this exceptional barrenwort. From pretty scimitar shaped green leaves rise wiry stems supporting clouds of star shaped flowers. The center of each flower is plum colored and the extending spurs are crystal white for a great bicolor effect. Extraordinarily long blooming from March well into summer- and sometimes longer if it feels like the weather has been perfect. Semi-evergreen to evergreen but we heavily advocate cutting the whole thing to the ground in February to make way for a fresh new year. New foliage is heavily mottled in red before settling to mid green. Part shade (open north exposure like the cool north side of your house is fantastic too) to shade in rich, well drained soil with consistent summer moisture. Spreads to several feet wide in several years. A truly great, long lived Epimedium that is very pretty all around. Moderate deer resistance.
Epimedium x ‘Golden Treasure’
One of our very best Epimedium introductions. Incredibly floriferous hybrid with golden yellow almost shiny flowers with a bright red cap on top. They appear in clouds above the foliage from March to June. New foliage is amber colored before settling in maturity to soft green. Evergreen but we think it looks much better if you remove the tattered foliage from the previous season in February- cut it to the ground to make way for a fresh new season. Blooms very heavily and they are vivid enough to spot from a distance. Vigorous clumping perennial for part shade to shade in rich, well drained hummusy soil. Regular summer water will spur repeat bloom but once established it easily endures summer drought. Avoid hot sun. to 20″ tall in bloom making a clump about as wide. Moderate deer resistance.
Xera Plants Introduction.
Epimedium x ‘Hinode’
Our own selection of a barrenwort with amazing sunset colored flowers. In fact ‘Hinode’ is Japanese for sunrise. The orange/red/pink/yellow adorable nodding flowers are born above the foliage on slender wiry stems. Blooms March-May. New foliage is mottled in amber and madder red before settling to medium green. Evergreen selection. Remove the winter tattered leaves in February prior to new growth. Clump forming to 1′ wide after 5 years. Full shade to part shade, not fussy about soil- avoid compacted dry clay soils. Regular summer water increases growth and maintains the plants luster. Woodland wonder.
Xera Plants Introduction
Epimedium x ‘Kym’s Gold’
This was found in the garden of our wonderful garden writer friend Kym Pokorny. Its a superior selection with profuse star shaped gold flowers with an amber collar around the lower petals. New growth is dramatic madder red with darker splotches before settling to a soft medium green. The new foliage color in combination with the flowers yields a very sophisticated plant. Clump forming evergreen perennial for part shade to shade. Rich, well composted soil with regular summer irrigation sends this cultivar into a wonderful place. To 18″ across and 1′ tall in bloom. Remove winter tattered leaves in February to feature the new foliage/flowers. Epimedium are resistant to slugs and not often bothered by deer.
Xera Plants Introduction
Epimedium x ‘Peter Rabbit’
Special barrenwort selection with some of the largest flowers in the genus that we grow. Arching flowers are pastel white and yellow and appear most profusely around easter time. Long long blooming from April into July. Tightly clumping perennial for RICH, well drained soil with regular moisture in part shade to full shade. New growth is mottled in red before settling to medium green handsome leaves. Plant with Omphalodes, Primula sieboldii cvs. and Vancouveria chrysantha. To 10″ tall and clumping. A personal favorite. The flowers are large and have unusual substance suspended from black wiry stems. Exquisite. Begins blooming later than other barrenworts.
Xera Plants Introduction.
Epimedium x ‘Pirouette’
Fanciful flowering barrenwort that we love for its large pale yellow flowers with spurs that point all in the same direction as if they were spinning. The flowers appear on long wiry stems above the foliage in March-May. Bold leaves emerge amber before settling to a nice mid green. Elegant perennial for deep rich soil in part shade to shade. To 18″ tall and twice as wide in great time. Often re-blooms into summer if conditions are favorable Evergreen. Cut back winter tattered foiiage in February for springs oncoming show. Deer resistant.
Xera Plants Introduction.
Epimedium x ‘Raspberry Cascade’
Searching the universe for a truly red flowered barrenwort- this seedling came along and it has more than just that. Large, profuse nodding flowers are true raspberry red with white tipped spurs. Blooms appear continuously from April to July and sporadically after that. Additionally the new foliage is amber with soft red splotches settling to a soft glossy mid green. Tightly clumping perennial for rich, well composted soil that retains moisture in part shade to full shade. Tolerates dry conditions when established. Evergreen, remove winter tattered leaves in February to make way for the new spring show. One of our best introductions. Long lived, easy to grow perennial for shade.
Xera Plants Introduction.
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
Epimedium x warleyense
Very pretty thin spreading Epimedium with soft amber new growth accompanying spikes of fairly large amber orange flowers with a soft yellow center. To 20″ tall in bloom the new foliage on this mostly deciduous perennial settles in at about 1′ tall. Spreads underground and not compactly. Give it room in a woodland to roam. Rich, moisture retentive soil with regular summer water. Part shade to high overhead shade. Easy woodland perennial for spectacular early spring effects. Moderate deer resistance.
Erica arborea ‘Albert’s Gold’
Very cool selection of Tree Heath that has exciting acid green/chartreuse foliage- brighter when new and masses of white flowers that smother the foliage in spring. Tough evergreen shrub for full sun and very little summer water when established. To 5′ tall and 4′ wide in 7 years for rich to average well drained soil in full sun with good air circulation. Spent flowers remain on the shrub and morph to a rust color with time- giving the whole shrub a rusty/chartreuse combination of colors. Not for formal gardens. This member of the mediterranean garrigue is drought adapted and cold hardy. Moderately fast growing. Showy in spring bloom.
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.
Erica terminalis
Tree heathers fascinate us and this widespread species of southern to northwestern Europe makes a fantastic, drought adapted garden plant. Fine needle like green foliage lines strongly vertical growth. In mid summer the tips of the stems produce many urn shaped pale pink blossoms that are showy for up to 6 weeks. Following the bloom period these remain on the shrub and turn a russet color adding to its charm. To 3′ x 3′ in 4 years. Full sun and well drained average soil with light summer water to establish. Once you have it going it requires no supplemental water. Great for dry areas, gravel borders, hellstrips. Excellent fine textured shrub that develops a shredded gnarled brown trunk with time. Moderate deer resistance. Gains drought adaptation with age. As with most ericaceous plants it must build up a large root system over time and then it is drought adapted and will sail through the driest summers without fainting.
Erigeron glaucus ‘Bountiful’
Such a long, long, blooming tough and dependable native this forgiving perennial outshines all other cultivars in the size of each flower. The many rows of glowing lavender petals that characterize this fabulous perennial outline nearly 2″ wide flowers. They begin in earnest in late May and proceed unabated until early autumn. If the flowers become tired or scorched simply cut it back and wham! You’re quickly back in business. Adaptable to many soil types and will subsist on only natural rainfall but occasional deep soaks in summer reaps rewards. To 10″ tall forming a round perennial to 18″ wide. Full sun, to very light shade. Pollinator masterpiece. Oregon native plant.
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
Erigeron glaucus ‘Cape Sebastian’
Beach Flea Bane or more popularly Oregon Beach Daisy is a phenomenal native perennial for our climate. Low and spreading a continuous supply of periwinkle/violet daisies with a yellow center appear from late spring to autumn and occasionally in winter. To just 8″ tall it forms 2′ wide spreading clumps. Simple spoon shaped green leaves. In its native environs which is the cliffs immediately adjacent to the beach it can cling precariously which shows it has sturdy roots. Full sun to light shade and regular irrigation or absolutely none when established. This floriferous and larger flowering selection is from the southern oregon coast. Excellent performance in hells strips..at the front of borders. This excellent semi-evergreen native perennial should be everywhere. Cut back hard after blooming to tidy the plant, keep it compact and encourage more flowers. Oregon native plant.
Erigeron speciosus
Showy daisy- though that is far too vague for this tough and graceful wildflower. Native in separate parts of the state this summer blooming perennial inhabits meadows and fields of the Willamette Valley. Rows of very fine soft pink petals surround a green/yellow center on 18″ stems June-August. The pretty daisies come in a group and then appear sporadically until frost. Loved by pollinators this is an authentic component of Willamette Valley meadows. Average to enriched soil with regular water to establish, in subsequent years it can survive on rainfall alone. Plant with Prunella vulgaris var, lanceolata, and Erigeron glaucus for a midsummer blooming native vignette. Long lived low maintenance perennial that goes completely deciduous. Widespread in the northwestern states of the US. Our version is from seed native to the Willamette Valley. Loved by butterflies and even good beetles. Clump expands to 2′ wide in time. Not bothered by deer. Simple, tough, wonderful native perennial. Full sun. Oregon native plant.
Erigeron x glaucus ‘Wayne Roderick’
Possibly a hybrid this is a spectacular perennial in our climate where it produces a non-stop supply of amethyst blue daisies with a yellow center from spring unabated to autumn. And occasionally in winter. A rosette forming perennial that sends up its clumps of flowers on vertical 6″ spikes. Loved by all pollinators with a special emphasis given to butterfies. Carefree, low water western native perennial with consistent excellent performance. To 18″ wide in time. Light, consistent summer water encourages re-bloom. Nice little cut flower. Rich, to average, well drained soil in full sun. Avoid rambunctious competition from other perennials. Mix with Agapanthus, Calamintha ‘Montrose White’. Even effective in containers. Oregon native plant.
Eriophyllum lanatum
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.
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.
Eryngium agavafolium
Evergreen Eryngium that we love. The glossy deep green strappy leaves are fiercely armed and form large rosettes. In summer 28″ spikes produce bright green clover like orbicular flowers on a divided scape. You won’t draw rattlesnakes but you will draw bees. Cool looking plant that is easy to grow in rich to average well drained soil Good appearance even during winter. Remove the flower scape when the blooms start to turn brown- not as pretty. Sexy plant that requires no summer water and just full sun. Long lived. I see boulders and Cacti and grasses and gravel. Sexy rosettes.
Eryngium bourgotii
Very blue, oh so blue shorter Sea Holly that has pretty unusual leaves as well as stunning flowers. Crinkly sage green leaves are prickly and outlined in fine white. From this batch of foliage the flowering spike attains about 20″ inches before producing the metallic sky blue star shaped flowers. Very pretty and it will instantly draw pollinators. Remains in bloom for 4-6 weeks from early to mid summer. Full sun, rich, well drained soil and little summer water when established. Tough but pretty perennial that is very long lived. Increases in width each year to 2′ wide. Excellent candidate for the hellstrip, the front of the border or gravel gardens. High deer resistance. Completely deciduous in winter.
Eryngium giganteum
Miss Wilmotts Ghost. As the legend goes Miss Wilmott would stealthily drop the seeds of this biennial into the gardens of those she visited. Sneaky girl. The plant would germinate and produce a low inconspicuous rosette of leaves the next year. The following year a tower of ghostly gray collared huge flowers on branched stems would appear- seemingly form nowhere. Freak. But my kind of freak. A really cool looking plant in bloom that photographs amazingly well by the way. To 3′ tall for full sun and open disturbed sites. It will reseed reliably in those conditions. The seedlings are easy to spot and move when they are very young if you desire a new spot. Makes a groovy large cut flower. This is the flower on our logo. High deer resistance. Drought adapted.
Eryngium pandanifolium var. lesseauxii
Fun tall growing sea holly that may be impossible to pronounce but its easy to grow. Upright growing finely serrated or prickly leaves first make a low 2′ wide rosette then when it feels like it- usually the second year a big as spike rises with a divided scape and tons of off white prickly clover like flowers dot the stem tips. Its cool. This whole perennial is cool and its slightly hardier than the species. Very cool. Evergreen perennial for full sun and just about any well drained soil. Flowers rise to 5′ tall and with time there will be many spikes. Pollinators arrive in droves to pollinate this very unusual but architectural perennial from South America. High deer resistance.
Eryngium yuccafolium
Rattlesnake MASTER! Great common name for a wonderful perennial that fits the modern aesthetic perfectly. Low rosettes of silvery serrated pointed leaves are subtle. In summer 30″ branched spikes produce rounded clover-like white balls- these are the flowers and they remain showy for weeks and weeks before finally turning brown in late summer- that the time to remove them. This robust member of the carrot family is sure draw for pollinators and even works well as a huge architectural cut flowers ( the flowers up close kind of smell bad- never smell an Eryngium you’ll regret it) but the fragrance is only detectable up close. Amazing with ornamental grasses. A flower with great presence that makes everybody else look better. Photographs well. Full sun to very light shade in any well drained site. Light to little summer water. Completely winter deciduous. High deer resistance. Rosettes increase with time and so do blooms spikes. Long lived.
Escallonia ‘Compact Pink’
As they say you can’t have suburbs in Oregon without Escallonia. Its a prerequisite. And they are incredibly tough, useful shrubs. Drought adapted, they have glossy evergreen leaves and grow moderately fast. This dwarf variety is conveniently small. Compact and dense growing to only 2′ x 3′ in 7 years. The glossy leaves make a fine backdrop to the clusters of small red/pink flowers that come in abundance in early summer but also sporadically year round. Incredibly drought adapted when established sailing through a whole dry summer without suffering one bit. Avoid exposure to subfreezing wind with this shrub it can burn- but as with all Escallonia recovery is mind bogglingly fast in spring. Loved by hummers and bees and pollinators in general. Very easy to go grow and always looks good. Moderate deer resistance. Chile.
Escallonia bifida ‘Compact White’
Useful, tough and good looking evergreen shrub that has glossy deep green foliage and masses of small tubular white flowers for months beginning in June. To 5′ x 5′ in 12 years for virtually any well drained soil, including clay. Excellent cold hardiness and totally summer drought tolerant. No water necessary. Hedges, specimens, holding plant for rough areas. Takes any amount of pruning. Excellent performance at the Oregon Coast This ever blooming shrub thrives with little care in the roughest situations. Not bad in a woodland and very tolerant of deer. Unmolested from pests or disease in general. Clean looking shrub. May be pruned very hard to resize, rejuvenate, but that is rarely necessary. Pretty clean white flowers. Excellent fast evergreen hedge. Chile.
Eschscholzia caespitosa
Golden poppy is native to the inland valleys of southwest Oregon. This charming annual is much more delicate in habit and color than its more common bolder cousin Eschscholzia californica the ubiquitous California poppy. This little jewel demands a hot sunny location in soil that is average, and not improved. It will self sow locally but nothing like its cousin. This demure little poppy blooms from late April to mid-June. Full sun is vital. Mix this charmer with other similarly adapted annuals. Collinsia grandiflora, Plectritis congesta, Gilia capitata. Very deer and rabbit resistant. Water potted plants to establish, resown babies in the future can get by on natural rainfall alone. Oregon native plant
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.
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.
Eschscholzia californica ‘Pretty in Pink’
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
Eschscholzia californica ‘Purple Gleam’
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
Eucalyptus archeri
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.
Eucalyptus gunnii
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.
Eucalyptus kybeanensis
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.
Eucalyptus parvula
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.
Eucalyptus pauciflora ssp. debeuzevillei
Jounama Snow Gum is repeatedly one of the cold hardiest Eucalypts and it is excellently adapted to our climate. Gray/blue scimitar shaped leaves are pendant on a spreading umbrella shaped frame of a tree. Often the trunk forks just after emerging from the ground into multiple handsome stems. This increases the surface area where you can enjoy the ravishing exfoliating bark. Bark drops in late summer to reveal python like patches of taupe/grey/green and is showy through winter. In autumn the upper branches are decorated with small fluffy white flowers. One of the few Eucalyptus that will endure subfreezing wind- in fact this tree has been hardy to brief dips to 0ºF (-18ºC). Explosively fast growing when young to 35′ tall in just 7 years. Give it room. Light summer water in virtually any well drained soil- including clay. Do not stake. Let it produce its own sturdy leader. Sheds ice and snow like a champion. Though this is a subspecies of Eucalyptus pauciflora- a snow gum just like E. p. ‘Niphophila’ there are several differences from that tree. The leaves on E. p. debeuzevillei tend to be wider and more substantial than ‘Niphophila’. Also, that gum nearly always forms several trunks. This is less common with Jounama Snow Gum and in my experience it is a slightly taller tree. It can also vary in its habit from being very wide and spreading to skinny and fastigiate- its simply the luck of the draw and you cannot decipher this future habit as a seedling. Avoid heavy watering in hot conditions and site in a well drained place. Its completely drought tolerant and should be treated that way. Winter water when its cool is irrelevant. Overall it is a fast, healthy, and easy to grow tree in just a short amount of time.
Eucalyptus pauciflora ssp. niphophila
Snow gum is a wonderful cold hardy tree for the Pacific Northwest. Lance shaped gray foliage is pendant and handsome year round. This rapidly growing tree thrives in full sun and virtually any soil save for boggy conditions. In just a few years it develops amazing python mottled bark in tones of gray/tan/olive green. The bark sheds in mid-summer and can be a bit messy. Site accordingly. Grows 4′-5′ a year when young. Irrigation just increases this growth rate. Stake only when VERY young then let it form a sturdy trunk on its own. The vast majority of this Snow gum will form multiple trunks. Its possible to select one sturdy main trunk when young- pay close attention as they grow very fast. To 30′ tall and half as wide in 10 years. Snow gums have a weird habit of growing horizontally before reaching upwards. This is natural. Handles ice and snow no problem. Cold hardy to brief dips to 0ºF- but not lower. Mountains of Australia. White fluffy flowers in clusters in winter. Avoid all shade.
Eucalyptus perriniana
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.
Euphorbia rigida
This plant is an early spring blooming staple of gravel gardens and pairs great, vivid, chartreuse flowers with symmetrical blue/gray succulent trailing foliage. To 18″ tall and up to 3′ wide when happy. Vivid flowers first color up in late winter and remain shockingly beautiful well into spring. Often re-seeds in open disturbed sites. Seedlings are easy to spot and dispatch or move. Give this trailing plant room to grow in full sun and very well drained soil of average to poor fertility. it thrives in rich soil and may become a tad rambunctious and may be shorter lived. Average conditions. A natural friend for blue flowered plants.
Euphorbia x ‘Copton Ash’
Well behaved lovely early summer blooming Euphorbia hybrid with fine blue foliage and umbels of chartreuse flowers that remain effective on the plant for 4-6 weeks. Easy to grow clump forming perennial that is winter deciduous. Foliage to 10″ tall supporting the flowers to 14″ high. Sterile hybrid- will not reseed or become a pest. Long lived perennial for full sun and rich to average well drained soil. Light summer water. Excellent en masse. Cut back spent stalks in winter to make way for a whole new crop of stems/flowers. Good deer resistance. Drought tolerant.
Euphorbia x ‘Dean’s Hybrid’
FANTASTIC long long blooming easy to grow and spectacular Euphorbia hybrid. Large clumps support wide umbels of electric gold flowers. They appear in spring and are effective on the plant well into summer. Foliage is fine, mid green and is a great backdrop to the never ending flowers. Semi-evergreen. A beautiful and valuable perennial for full sun and well drained soil. Little summer water required. Excellent heat tolerance and performance in hell strips. To 2′ tall and forming clumps a little wider. Mix with Salvias, Eryngiums for visual perfection and the same culture. Moderate deer resistance.
Euphorbia x ‘Purple Preference’
Excellent Euphorbia hybrid selected for deeply hued purple foliage that it pairs with early spring panicles of large chartreuse yellow flowers. Semi-shrubby evergreen perennial for RICH soil that drains quickly and light summer irrigation. The foliage goes through several hues before settling to deep green (purple to mustard to green). To 3′ tall and half as wide. Completely sterile hybrid that will not reseed or become a pest. Long season of bloom and interest. Appreciates the good conditions. raWonderful contrast between the chartreuse flowers and purple emerging new growth.
Fabiana imbricata ‘Violacea’
Chilean heather is not a heather at all rather it is in the solanum family- its related to tomatoes. Tubular violet purple flowers smother the very fine scale like foliage from late spring well into summer. In bloom its a pretty effect that attracts hummingbirds and other pollinators alike. Fast growing evergreen shrub for poor, unimproved well drained sites. To 5′ tall and 3′ wide in 5 years. Prune after flowering if you need to resize contain. Cold hardy and adapted to the poorest soils….its native on sand. Very drought adapted, little summer water when established. Excellent deer resistance. Flowers have a pervasive honey-like fragrance- and they look like miniature purple honey combs too.
Fatshedera x lizei ‘Annemieke’
Hybrid between English Ivy and Fatsia that makes a fascinating decumbent (sprawling) evergreen shrub for part shade to shade. May be diligently trained as a bold evergreen vine. Large glossy green leaves with a center of gold are striking year round. To 9′ tall as a trained vine or as wide as a decumbent shrub on the ground. Takes drought when established. Small off white orbicular flowers in autumn. Sterile. Good deer resistance. Gains width with time and can cover an entire wall. Blooms in autumn do not produce viable fruit. You can prune this shrub/vine back hard and it will regrow as a smaller shrub. Very good bold solution for dank dark walls and planters under over hangs. Cold hardy to 5ºF.
Fatshedera x lizei ‘Variegata’
Bold sprawling shrub or vine that is a hybrid between Hedera and Fatsia. This form has large leaves outlined in cream. Evergreen that seeks shade but is surprisingly sun tolerant too. It may be grown as a free standing shrub, bold ground cover, or trained as a vine. Very nice in winter containers too. Well drained soil average to rich fertility. Light water. White flowers in autumn never set viable fruit. To 4′ tall and sprawling 8′ wide. Moderate deer resistance.
Fatsia japonica
Classic PNW shrub False Japanese Aralia as it has been called is a bold, tough, evergreen shrub for part shade to shade. Moderately fast growing to 7′ x 7′ in 7 years. Part shade to shade in rich to average well drained soil. Regular summer irrigation or none when established. Takes dry shade like a champion. Long lived shrub for bold effects in woodlands, large landscapes. Cold hardy and good looking year round. In time it forms stretching trunks with the foliage clustered at the tips. Takes well to hard pruning which should be done in late spring- water well after doing so. Large divided spikes hold white orbicular flowers in autumn. Seldom sets seed in our climate. Moderate deer resistance. Native to Japan.
Fatsia japonica ‘Murakamo Nishiki’
Fatsias are invaluable in our climate for their tropical good looks, and overall hardiness. They endure dry shade with aplomb and in autumn they explode into exotic bloom with large stems supporting orbicular white flowers. This cultivar has leaves with an interior zone of yellow. Slower growing than the species it will eventually top out at 6′ x 6′ in full to part shade in rich well drained soil. Light summer water. Moderate deer resistance. Cold hardy and very easy to grow. Light consistent summer water speeds growth.
Fatsia japonica ‘Variegata’
Not easy to find this is a most regal evergreen shrub. The large palmate leaves are emargined in splashes of white. In autumn the large candleabra like flowers structures are themselves variegated white. White orbs of flowers at the tips. To 8′ x 8′ in 7 years. Full shade to part shade in average to rich well drained soil. Adapted to dry shade. Drought adapted but tolerates regular irrigation. Fast growing. Variegation becomes more conspicuous as this shrub ages. Moderate deer resistance.
Festuca rubra var. juncea ‘Patrick’s Point’
A west coast native grass that ranges from British Columbia to Southern California- usually near the beach. This form is exceptionally blue and so pretty as a year round evergreen presence. To 9″ tall and spreading at a measured rate by stolons slowly expanding the plant to several feet wide. Forms an incredibly dense cover and weeds will seldom compete with this climate adapted grass. In late summer and not profuse 8″ stems hold gray floral spikes. This is along lived, easy to grow grass that does not die out in the center or poop out after a few years. In fact it would make an admirable lawn substitute. This form is from Humboldt, County in CA and was named for the small town where Greg lived as a child- so we had to grow it. And damn it turned out to be a fine, evergreen, native grass. Full sun to light shade and little to no summer water once established. Not fussy about soil and not a rambunctious thug unless soil is overly enriched- instead give it oxygenated average soil. Excellent among drought adapted shrubs and especially nice interplanted with Pacific Coast Iris. Fine dense foliage is bright blue in summer turning to more of a greenish hue during the cooler months. Excellent winter appearance. High deer resistance. Oregon native plant.
Frangula (Rhamnus) californica ‘Eve Case’
Excellent evergreen west coast native shrub that is always at its best. Large, glossy deep green foliage clothes the stems densely on a compact but large growing form of California Coffeeberry. Insignficiant tiny green flowers in summer/autumn turn into crops of red then brown berries. Very showy until stripped by wildlife. This species is native from SW Oregon through Calfornia west of the mountains. Completely drought tolerant- in fact it resents summer water. To 8′ x 8′ in 5 years. Wild areas, informal low water hedges, blasting urban heat. We should take advantage of these climate adapted west coast plants for the toughest sites. Great deer resistance. Oregon native plant
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
Frangula (Rhamnus) californica ‘Leatherleaf’
A really cool version of California Coffeeberry which is also native to SW Oregon. Thick deep green rounded leaves clothe madder red stems densely on this large shrub that can achieve tree like status with time. Insignificant green flowers transform into brown then black berries eaten by wildlife. Incredibly drought adapted never needing ANY supplemental water. Well drained soils in full sun. To 9′ x 9′ in 8 years. Pruning can keep it lower and it would make an admirable hedge. Cold hardy to near 0ºF. Often not bothered by deer and one of the best deer resistant hedges for rural area- put a test plant out first to see if your deer are different It grows quickly with little to no irrigation.
Oregon native plant
Frangula (Rhamnus) purshiana
AKA Cascara or Cascara sagrada. This is a widespread small tree to shrub in the northwestern part of the United States to SW Canada. West of the Cascades its found in almost every biome. It can be a wind contorted shrub on blasting headlands at the coast. In the Willamette Valley its common where birds drop the berries/seeds on fence rows and it borders fields with native roses and Oso Berry. Its even found in the Bitteroot mountains in Montana/Idaho. It was frequently used by indigenous people as a laxative. Cascara is a small round crowned tree/shrub. In drier locations it is more shrub like but in deep, rich soil with access to water it can grow to be a thirty five foot tree. Large round alternate leaves turn dark green and glossy in summer. In May and June the tiny greenish flower appear and transform into red fruits by autumn. This is the mechanism that makes this plant so widespread, its dispersal by birds. A lovely little straight trunked shade tree that requires almost no water once established. It functions as an understory component as well. Full sun to quite a bit of shade, including dry shade. Easy to grow and climate adapted. Average life span 35 years. In winter its very symmetrical open branch structure is handsome. Fall color is soft yellow to chartreuse and not especially showy. Oregon native plant
Fremontodendron x ‘San Gabriel’
For people with HUGE gardens that they don’t want to water but still require a floral show there is this west coast native Flannel Bush to occupy beautiful space. Fur covered maple shaped leaves are deep green on top with a reverse of tawny brown. Avoid this fur it causes dermatitis and you don’t need that. Rapid growing evergreen shrub for full sun and poor soils and absolutely NO summer water. That can lead to root molds and death and at the very least rank growth that does not harden for winter cold. Instead neglect and stand back as this 15′ x 15′ monster of the Chaparrel produces a two month parade of 4″ wide cupped gold flowers. A large specimen in full bloom causes the heart to stop. Nice espalier too. Moderate deer resistance. Neglect is the flannel bush’s friend.
Garrya elliptica ‘James Roof’
Wavy Leaf Silk Tassel is a beautiful winter blooming evergreen shrub native to the Oregon coast from Lincoln county south to Santa Barbara county California. Amazing 1′ long silver gray tassels from late fall last through winter. Large shrubs have the appearance of a chandelier. Tassels dry and abort the plant by late spring, then its just a clean evergreen To 12′ x 12′ for well drained soil in full sun with good air circulation. Some leaf burn in the coldest winters. Eventually it can become a multi-trunked tree. Extremely drought tolerant when established, never needing supplemental summer water. Prune AFTER flowering. Excellent espalier. Spectacular in full bloom– which lasts for two months in mid-winter. Full sun to quite a bit of overhead shade. Avoid strong subfreezing east wind. Oregon native plant.
Garrya x issaquahensis ‘Glasnevin Wine’
Large exceptional evergreen shrub that is a hybrid selection between two native west coast species. To 12′ tall and nearly as wide the merlot red stems support wavy deep green leaves. From December to April 3″ long wine red tassels are graceful and showy. Fast growing shrub for average to rich well drained sites in full sun to high overhead shade. Little water when established. Slightly hardier to cold than G. elliptical ‘James Roof’. Great low water hardy fast screening shrub. Easy to grow. Give it space to fill out. Prune AFTER flowering has ended in spring if needed. Appreciates good air circulation. An open exposure or this is also is a great plant for the high dry shade of native Oaks.
Oregon native plant
Genista aetnensis
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.

Geranium tuberosum ‘Slender Silver Leaf Form’
This is a really pretty take on the more common form of Geranium tuberosum. Rather than brilliant deep purple flowers this very distinct variety makes due with the hues pink and lavender. The foliage on this spreading bulb is what really shines. Deeply incised palmate leaves are brushed with silver hairs. This pairs with the more pastel colors of the flowers in a very good way. Rich soil to average soil in part shade. Once established rely only on what falls from the sky. Bloom is 4-6 weeks April to early June and the flowers wave above 18″ stems. Vigorous and healthy and not bothered by any pests, that includes slugs and snails who will leave it strictly alone. Goes quickly dormant with summer heat- disappears entirely. Very easy and satisfying perennial to grow in Cottage gardens, spring borders, will flower gardens. Combine with spring ephemerals and bulbs. Sophisticated cultivar that improves the species.
Gilia capitata ssp pacifica
We once grew this form of Gilia capitata as our own local species. WRONG. We compared it to the southern Oregon Coastal variety ssp. Pacifica. That form is shorter but blooms are a distinctly darker blue. Everything as for the species Reseeds faithfully in OPEN disturbed sites with little competition from invasive weeds/turf grasses. This thick, stout variety makes a wonderful cut flower. It also has the same attractive properties that make it one of the best native pollinator plants. To 18″ tall and forming patches that reliably re-sows each year. See above care. WE love both forms of this Gilly Flower made famous by early European settlers. They’ve spread this wild flower around the globe where it has become naturalized in parts of New England into E. Canada. Not a bad weed but an example of something from here with adaptation to another climate. Oregon native plant.
Gladiolus dalenii ‘Bolivian Peach’
Hardy happy and elegant perennial gladiolus that is perhaps just a species but market…y’know. To 3′ tall it opens soft peach and yellow wild looking flowers up a sturdy scape. Multiplies quickly in rich well drained soil and a patch will form yielding multiple blooms and a great source of cut flowers. Nothing like hybrid garden gladiolus instead decidedly more wild looking and we LOVE that. Very easy to grow, tough and hardy. Emerges late often not until April be patient. Regular summer water and full sun will prevent the towers from falling over. If they do simply cut them and bring them in the house. Moderate deer resistance.
Gladiolus papilio
GLADZILLA! Thats what we call this rambunctious, prolific and all too easy species Glad. Blue/gray foliage gives way to serpentine spikes lined with curiously colored cup shaped flowers. The exterior of the petals is best described as dove gray. The interior is more complicated with zones of yellow, purple, and brown. Lovely cut flower.. The scape rarely stands straight up- accept that, it makes cool arrangements. In the ground its kind of a monster. It lives to multiply and in soil that too rich you will end up with 100,000 in a short time. Don’t torture it just don’t pamper it. Great plant for the rough life of the back 40 or a forgotten corner of your yard. Don’t recommend putting it in a hellstrip as it would spread so fast you would soon find Gladzilla monoculture. Completely winter deciduous- nothing there. Emerges relatively late in spring but it goes fast. Excellent cut flower. Strong deer resistance. Water? Yeah.. if you want.
Gladiolus tristis ‘Moonlight’
Unusual species gladiolus that is actually an early spring bloomer and at night possesses a wild sweet powerful perfume. Very thin grassy foliage forms clumps to 10″ tall. It appears in autumn with the first rains after summer dormancy. In March flower spikes rise to twice as tall as the leaves an open wild looking simple luminous yellow flowers. They have fancy markings on the inside lower two petals. At dusk the perfume arrives and does it flow. I’ve smelled this flower from 20′ away on mild spring nights. It makes a great cut flower but this mysteriously diminishes the perfume. Full sun and VERY WELL DRAINED soil- such as a rock garden or a hillside. It dislikes competition so give it space. Excellent with a mulch of gravel. Don’t plant this in a crowded bed in rich wet soil it will die out or it will quickly be overwhelmed. Fun plant to grow. Needs no supplemental water cause its totally dormant by summer anyway.
Gladiolus x dalenii ‘Boone’
Found by a NC extension agent at a very old homestead in Boone, a cold mountain town in the western part of the state. This very old hybrid cultivar of Gladiolus dalenii and ? Its also listed at the hybrid G. x gandavensis. A wonderful COLD HARDY perennial Gladiolus that we dearly adore. Pale orange outside simple petals surround a center of intricate coloring. Green, pink, yellow. Very wild compared to the big border babies but a true multiplying perennial that will quickly form a clump with a dozen or more flower spikes. Blooms appear for 4 weeks in the middle of summer. They rise above a healthy bunch of soft green spear shaped leaves. Full sun and rich soil with no standing water in winter. To 22″ tall and spreading to 1′ wide in about 5 years. Not bothered by deer – YAY and a great perennial for rural areas. In urban places the only protection it requires is from your flower arranger friends cause the subtle color combination in this flower can be tastefully echoed in a bouquet. Naturally cold tolerant and very easy to grow. Protect from Cutworms on emergence. Long lived perennial
Glaucium flavum ssp. auranticum
The brilliant ORANGE flowered horn poppy. Variety is the spice of life and we had of course to grow this form of one of our favorite perennials. HUGE true orange flowers are up to 5″ across and they glow from quite a distance. In combination with the blue rubbery foliage- WOW. Full sun and well drained poor to average soil with light to no summer water. Adapts to richer conditions but this will shorten its lifespan. Large blue long “horns” protrude from every direction where a flower was present. Self sows and comes true from seed. Leave the seedling where they are- transplanting this genus can be dicey. Enjoy it as the feral wildflower that it is. High deer resistance. 2′ x 2′. Dies to a low rosette in winter. Average lifespan: 3-5 years.
Globularia cordifolia var. nana
Low growing globe daisy that makes a great small scale evergreen ground cover. In mid-spring rising up from the small paddle shaped leaves spikes are topped with spheres of fluffy steel blue flowers. Spreads moderately fast on well drained sites with light summer water. Full sun to part shade. To 4″ tall- foliage prostrate and spreading to 18″ wide in several seasons. Great in rock gardens. Cold hardy, drought adapted and easy small scale plant. Very dense growth pattern inhibits weeds on a small scale and the glossy deep green foliage is presentable year round. Not a widespread ground cover. Excellent between pavers and rocks. It handles compacted soils with aplomb. Light summer water but completely drought resistant when established. Charming plant.
Grevillea australis
Alpine Grevillea is a cold hardy, handsome, adaptable evergreen shrub that is good looking at all times. In late winter/early spring flossy white flowers explode over the bush and emit an intense honey fragrance. Each small leaf is olive/ochre green on the surface and silver below. Dense, fine textured very rounded compact shrub to 4′ tall and 5′ wide in 5 years. Maxes out at that height but continues to gain width. Avoid enriched, over-improved soil. Best in unimproved native or even poor soils with sharp drainage. Little water ever once established. Cold hardiest Grevillea taking temperatures to just near 0ºF with no problem. Tolerates subfreezing wind as well as ice and snow. Easy to grow if left strictly alone. It may be pruned in spring to limit the size- prune tips. Very good landscaping plant. The powerful honey fragrance of the flowers is detectable for quite a distance on warm days. But for this it would make a good cut flower- fragrance is a little too strong. Cut branches last for several weeks in a vase and foliage is handsome. Takes very well to pruning. Good deer resistance. Video below is of a plant in full bloom. Takes a moment for the video to load. Not tolerant of shade at all. Hates it. Revels in full hot sun. Limited quantities.
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.
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
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 juniperina ‘Molonglo’
Juniper leaved Grevillea that is a low spreading ground cover. Grass green needle like foliage plays host and is often obscured by masses of curly apricot yellow flowers. They peak in late spring but occur almost any time of year. Poor, well drained soil in full sun with no supplemental water ever. To 2′ tall by 6′ wide in 5 years. Supremely adapted to the heat and drought of parking strips. Prickly foliage deters animals- and even people. Incredibly floriferous shrub that gains cold hardiness with establishment. Loved by hummingbirds. Protect from subfreezing wind. No fertilizer. Dense enough growth to smother weeds Best with total neglect. Loved by hummingbirds. Little water when established. Amazing in bloom.
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
Grevillea juniperina ‘Pink Lady’
A pretty shrub for a protected location. Compact growing evergreen shrub with medium green needle-like foliage. To 2′ x 4′ in 5 years. Nearly year round-but peaking in spring, copious light pink curly flowers are loved by hummers. Protected location in virgin, un-improved soil. Drought adapted when established. Excellent on a hot south facing slope- avoid crowding by other plants or an exposed cold site. Its possible that this is a hybrid and not pure G. juniperina. However, there is so much variability in this species that we are unsure. Extremely drought tolerant but it seems to grow faster and bloom more profusely with light water in summer. This plant is great at the Oregon coast where it is in nearly full bloom year round. It has survived undamaged in my garden for 9 years and has endured temperatures to 10ºF undamaged. It could be much hardier (when established). Limited qualities.
Grevillea juniperina ‘Xera Ember’
Our improved selection of the Juniper Leaved Grevillea with darker orange to near red profuse flowers and a more compact habit. To 2′ x 4′ wide in time the prickly grass green foliage of this spreading evergreen shrub allows the vivid curly deeply colored flowers to shine. Blooms nearly year round with a peak in mid to late spring. Loved by hummingbirds. Completely drought adapted- never needs supplemental water. Poor to average soil that drains but has never been amended or fertilized. Awesome candidate for a hot hillside or a protected hot south facing wall. Spectacular in bloom. Requests neglect- you should oblige. Hardy to around 7ºF. Full sun. High deer resistance.
Xera Plants Introduction.
Grevillea miqueliana var. moroka
Round leaf Grevillea is a great hardy species from the highest elevations in the mountains of SE Australia. Handsome wavy round evergreen leaves frame showy pendant flower clusters from January to June. The sunset colored flowers feature orange/yellow/pink in various incarnations depending on the temperatures. Loved by over wintering Anna’s hummingbirds. Any reasonably well drained soil that has NOT been amended. Native soils are perfect, and tolerant of clay as well as sand. Great on slopes. Fast, large growing to 8′ x 8′ in 6 years. Sporadic flowers appear year round. Avoid fertilizers. One of the best climate adapted Grevilleas that we have grown. Grows very fast with little water. Full sun and a hot position. Listed as endangered/threatened in Australia where it occupies just a half dozen sites in the high mountains. Extra reason to grow this fabulous multidimensional shrub that is good looking year round and blooms for a long, long period. Light summer water is best as infrequent deep soaks when it is not hot. This shrub gains cold hardiness with establishment. Excellent sited where its roots can find protection and a cool respite. Large boulders, even pavers will help create this. A very rare Grevillea that is truly alpine in nature.
Grevillea rivularis
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.

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.
Grevillea victoriae ‘UBC Form’
Royal Grevillea is one of the most handsome shrubs that we can grow in our climate. Native to the highest elevation in Australia and then down to the middle elevations this species has been grown in our climate successfully for many decades. Large, long gray foliage is handsome year round and a great backdrop to the masses of orange pendulous flowers which are most prolific during winter. Loved by hummingbirds – Anna’s will stake out this shrub as one of the few sources of nectar during winter. Full sun to light shade in average soil with light, consistent water to establish. Avoid baking hot locations as this plant forms and sets its flower buds in late spring and summer and they hold until the cool of autumn arrives to open. If this plant becomes too hot or stressed it can abort these flower buds diminishing the following seasons display. So, an average position away from reflected heat produces the best blooming. Very good performance in cold rural gardens, enduring 5ºF with no issue. Very large growing to 12′ x 12′ and sometimes larger with time. May be pruned hard in early spring to both limit the overall size but to increase density and blooming wood. Great performance at the Oregon coast and in Puget Sound as well as the coast range and Cascade foothills. In the Willamette Valley the hybrids ‘Neil Bell’, ‘Octopinky’, ‘Poorinda Queen’ and the species G. Juniperina do not abort their flower buds in the hottest weather- and seem to perform more satisfactorily. Moderately deer resistant. Long lived. This form is from the University of British Columbia.
Grevillea x ‘Canberra Gem’
One of the easiest Grevilleas to grow in our gardens this free flowering hybrid requires a protected location but is surprisingly hardy when well sited. To 4′ x 6′ wide in 5 years, the needle like foliage is bright green and fairly crowded along the stems. Bloom begins in March and extends to July. A small amount of flowers appear year round.- clusters of spidery deep vivid magenta flowers. Very showy. Loved by hummers. Full sun and average to poor well drained soils. Great at the top of a hillside or next to the south wall of a house. No summer water, or compost necessary. You may water it weekly to establish and you can trail off as the plant grows. Native unimproved soils are what it loves. Cold hardy to the low teens. It has recovered from lower and we’ve seen established shrubs in protected places all over western Oregon. Fantastic performance at the Oregon Coast where it should become a staple landscape shrub. High deer resistance- and that includes Elk on the coast. Takes well to pruning after the first flush of bloom has ended. Hybrid between G. rosmarinifolia and G. juniperina. Evergreen. See video clip below.
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 x ‘Leanne’
Handsome evergreen shrub that displays masses of gold/old gold spidery flowers nearly year round- peaking in late winter into spring. Clean paddle shaped leaves are olive green on top and silver gray on the underside- a great combination with the flower color. Dense growing to 4′ x 6′ in full sun and poor to average well drained soil. Little summer water when established- extraordinarily drought tolerant. Loved by hummingbirds. One of the easiest to grow and fairly spectacular in full winter bloom. Excellent everblooming shrub for slopes, dry hillsides, low water areas. Avoid compost, nutrients. Tip prune if growth is too fast or rank and endangers the plant from rocking. ‘Leanne’ thrives on our own unimproved native soils. Full sun to very light shade and neglect. Excellent cold hardiness. Hybrid between G. victorae and G. juniperina. Avoid summer water which can leave it susceptible to phytophthera. It can tolerate ANY amount of extreme drought with no problem. Nice mounding habit for hot hell strips. Mixes well with Arctostaphylos, other drought adapted shrubs. Gains cold hardiness with age- establishment. Excellent garden shrub. At one point this and many other hybrids were known for the ranch, Poorinda where they were discovered/bred. That first moniker has been dropped in all of the varieties (Save for x ‘Poorinda Queen’- which, well. Cuz.) So, this is just Grevillea x ‘Leanne’ now. Why they made this change I do not know. Crazy Australians.
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.
Grevillea x ‘Neil Bell’
A chance seedling in Neil Bell’s Monmouth, Oregon garden has yielded one of the finest Grevilleas that we can grow. Neil graciously shared cuttings of this seedling to us. It then bloomed and turned out to be a fantastic shrub and we named it after Neil. Large evergreen shrub with dapper paddle shaped leaves olive green on top and gray underneath. Year round spidery pendant tomato red flowers appear- waxing and waning with the weather- they favor cooler weather. Fast growing and completely drought adapted. Water to establish then none in subsequent years. Takes well to tip pruning. Well drained average to poor soils that have NOT been improved. Adaptable to clay especially on slopes. Loved by hummingbirds and predominantly staked out in winter by Anna’s who recognize it as a superior food source. It has been cold hardy to 5ºF planted in the ground suffering no damage. 8′ x 8′. Cold adapted Grevilleas have flower buds insulated with fine fine hairs- this protects them from the coldest temperatures. Open flowers may be damaged by lows colder than 23ºF but new, protected flower buds will open in the next thaw so the display resumes quickly. Prune in early summer- this produces a denser shrub and will spur it to into bloom. Grevilleas may have as much as 1/3 of their mass removed annually and will regrow rapidly. This can be useful for shrubs that have grown too fast or rank and need to be stabilized by resizing. Cut branches with flowers last in a vase in winter and its a great time to have vibrant cut flowers. Do not water during very hot weather- it is adapted to the most desiccating heat and dry with no ill effects. Fantastic shrub. Protected location. Flower buds do not abort in hot dry weather.
Xera Plants Introduction.
Grevillea x ‘Poorinda Queen’
Subtle but beautiful hybrid Grevillea with fine needle-like foliage that produces a nearly constant parade of soft citrus orange spidery flowers. The perianth is soft orange and the protruding style is red. No matter the weather this carefree shrub seems to be in bloom. Heaviest flowering is in mid-winter just when the gardener needs it most. Large spreading shrub to 8′ x 8′ in poor, well drained native soil. Little to no summer water when established. Very very cold hardy enduring 5ºF with no damage. Give it room to spread as it can grow very fast. Takes light overhead shade if not too dense. Incredibly drought tolerant. Very difficult to propagate but we are always trying to make as much of this awesome shrub as possible. The intensity of the flower color shifts with the seasons gaining vividness with cooler temps. Wonderful winter blooming shrub. Grevillea victorae x Grevillea juniperina. A Xera favorite. Protected location. Very good in the city of Portland.
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.
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
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.
Grindelia integrifolia
Willamette Gumweed, Puget Gumweed is an important native late blooming pollinator plant. A native resident in the Willamette Valley along water courses and marshlands- It seems to excel in areas that are wet in the winter and bone dry in summer. That kind of adaptation begs for its inclusion in bioswales and to stabilize stream banks. In normal garden conditions gumweed – which derives its common name from the gummy coating on the leaves. It has a tar-like fragrance and is positioned on the leaves to decrease evaporation. It may also impart some resistance to saline conditions. In June-Sept. this large, spreading plant is decorated with corymbs of bright yellow daisy flowers. Immediately they are attended by pollinators. Its fascinating. The flower bud is densely armed with prickles giving this native daisy kind of a tough look. To 30″ x 30″. Full sun and rich to average conditions. Tolerates clay soils if you water it consistently to get the new roots into the clay soil. Once established it’s a very drought adapted plant. It also improves substantially under cultivation. Combine with Symphyotrichon subspicatum ‘Sauvie Sky’ and Solidago for a native prairie redux. Winter dormant. Seed grown from plants native to the Willamette Valley. Moderate deer resistance. Oregon native plant.
Hakea epiglottis
Beaked Hakea. Out of this world wiry shrub from Tasmania that forms nearly a tree with modified stems that serve as leaves.

Excellent cut material for groovy bouquets. Very fun to grow. Pronounced HAY-kee-uh.
Hakea microcarpa
Unusual tree/shrub from alpine areas of Australia into Tasmania with spiky modified phyllodes as leaves. The spiky leaves are blue green and it forms an airy conifer like large plant very quickly. In spring flossy white flowers crowd the blue green leaf axils and are showy for several weeks. Full sun and average to poor well drained soil. Little summer water once established. Fast growing in youth to its ultimate size. Cold hardy for us to 5ºF but avoid exposure to subfreezing winds. Proteaceous- do not fertilize or even add compost. Un amended native soils are ideal. Very attractive to birds who will use the leaves as perches. Humming birds love this plant in bloom as well. To 9′ tall and 6′ wide in 6 years. Great on slopes. Casts no shade- great textural element year round. High deer resistance. Very unusual plant- out of the ordinary and cool. Pronounced HAY-kee-uh.
Hakonechloa macra ‘All Gold’
The all gold form of the legendary Japanese Forest Grass. Forms spreading clumps of arching gold foliage. A bit more upright than the variegated variety ‘Aureola’. To 2′ tall and 3′ wide in rich, well drained soil with regular summer moisture. Full sun (with water) to part shade. Fall color is rich amber. Winter deciduous. Mixes in a contrasting way with the glossy deep black/green foliage of Beesia and provides the texture and grace to many bulky Hosta plantings. Appreciates an annual application of all purpose fertilizer. And it appreciates well amended soil. Water regularly for the first summer to not only establish but grow the clump. A pacific northwest classic by way of Japan. It also emerges just in time to hide the fading foliage of spring bulbs. Planted in close proximity smaller Narcissus, Muscari, and Crocus will have foliage neatly disappear as the clump of forest grass expands. Very good under deciduous trees.
Halimiocistus x wintonensis
Clever llttle rockrose that deserves a place in a protected, hot, sunny aspect. Sage green dense foliage is a great backdrop to the spectacular 3″ wide cupped flowers. They are white with a zone of maroon at the base around a yellow center. Fun! Blooms daily for 4 weeks in May-June. To 2′ x 2′ quickly in RICH well drained soil in full sun. Light summer water. Great performance in the reflected heat of hellstrips. Beautiful in bloom. Combine with native hardy annuals for a wonderful wildflower spring display. No water necessary. Forms a rounded shape.

Halimium lasianthum ‘Sandling’
Gray spreading upright evergreen shrub that celebrates late spring into summer with profuse 2″ wide bright yellow silky flowers with a conspicuous tomato red blotch at the base of each petal. Each flower lasts but a day but there is such a profusion of blooms waiting in the wings that they occur daily for 4-6 weeks from May to July. To 3′ tall and 4′ wide quickly in poor to average well drained soil. Water to establish then water lightly and infrequently during summer. Excellent performance in Hellstrips. Blooms simultaneously with Ceanothus ‘Victoria’ the blue and yellow blossoms a classic combination and both shrubs appreciate the same culture. Cold hardy to 5ºF.
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.
Halimium ocymoides
Golden rockrose (Halmium) is the other genus apart from Cistus. This dense rounded shrub to 2′ x 3′ is clad in evergray foliage and appreciates average, well drained soil in full, all day sun. Water to establish then only light occasional summer water. Blooms which are bright yellow and silky have a central zone of burgundy. One of the common monikers is ‘Black Eyed Susan Shrub’. Produces a great wildflower display for weeks in May to July. Lifespan is about 5-7 years but flowering is so profuse and long the risk is worth it. Cold hardy to 5ºF. Mediterranean native. Plant with Cistus, Grevilleas, Arctostaphylos, Pacific Coast Iris. Prune lightly after blooming has ended to shape, encourage a denser habit.
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.
Hebe ‘Inveray’
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.
Hebe ‘Wingletye’
One the best Hebes that we have grown that offers cold hardiness, showy flowers, and a useful low spreading habit. This ground cover Hebe with gray foliage and held on black stems spreads nearly prostrate to form a low dense shrub. In early summer the whole plant is smothered in deep violet purple flowers- among the showiest flowers of any cold hardy Hebe. Stems arch up and then immediately down cruising along at a moderate clip. To 6″ tall and 3′ wide in full sun and well drained soil. Light summer water when established. Excellent plant for slopes (the stems root where they touch the ground) as well as rock gardens. Placed near a wall or container edge and it will gracefully spill over the edge following closely the contour of any object. Plant density inhibits weeds effectively and it can make a useful ground cover placed on 2′ centers. Very tough little evergreen shrub and always good looking.
Hebe albicans ‘Pink Elephant’
One of our favorite Hebes. This dome shaped dense plant has new foliage that goes through some pretty showy transitions. Emerging tinted pink it takes on coral and light blue as well as pink before ultimately settling down to soft gray. The transition begins in early spring and lasts for months. In June small spikes of violet blue flowers add contrast. Cold hardy with average water needs for full sun and well drained RICH soil- this Hebe prefers more nutrients than others to really shine. Don’t be afraid to scratch in a handful of all organic fertilizer in early spring. To 2′ x 3′ in 5 years. Give it good air circulation with little crowding from other plants. Avoid watering when its blazing hot. Perfectly hardy to cold. Spectacular shrub. Offered only early in the season. Sells very quickly.
Hebe pinguifolia ‘Sutherlandii’
Indispensible alpine cold hardy Hebe with an astonishingly uniform dense habit. Rounded to 30″ tall and up to 4′ wide in time. Blue gray foliage is handsome at all times. In summer sporadic white flower spikes dot the plant. Full sun to light shade in average to rich well drained soil Light, but consistent summer irrigation. Especially important for it to be well hydrated before extreme heat (above 100ºF). Excellent hedge, massed as a tall ground cover. Very cold hardy- not bothered by our coldest winters and of alpine derivation in its home in New Zealand. Formerly known as Hebe sutherlandii. Excellent as low informal hedge or even massed as a symmetrical ground cover.This form has been consistently hardy down to 0ºF. Excellent performance in cold rural gardens. Tolerates some subfreezing wind. Xera favorite shrub.
Helianthemum ‘Annabel’
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
Helianthemum ‘Cheviot’
Sunroses are great flowery perennials for hillsides and the front of borders. Low growing gray evergreen foliage is a great foil to the 1″ pale pastel apricot flowers that obscure the whole plant for weeks in mid-late spring. To 8″ tall x 2′ wide. But back hard after flowering to encourage a denser more compact plant. Light, regular summer water is important- avoid total dust dry conditions. Mix with Pacific Coast iris and Penstemon heterophyllus ‘Electric Blue’ for a swoon worthy effect. Some deer resistance but not impervious. Each single flower lasts one day but masses of flowers appear opening in full sun, for weeks.
Helianthemum ‘The Bride’
The combination of silver evergreen foliage and the clear white pristine flowers of this perennial is exceptional. To 6″ and spreading May to June the foliage is obscurred by a daily supply of flowers. Very showy. Full sun and light but consistent summer water. Cut back hard when blooming has ended. This yields a more compact tidier plant. Good deer resistance. Banks, hillsides, parking medians. To 3′ wide.
Helianthus bolanderi
Serpentine Sunflower or Bolander’s Sunflower. Who doesn’t like sunflowers? I don’t know about you but they make me smile. There are several native sunflowers but this one is the cream of the crop. Native to extreme S. Oregon and extreme N. California this wonderful plant shines on the most difficult soils. Known as Serpentine Sunflower – Serpentine soil is a special substrate full of heavy metals- zinc, iron, copper. It prevents many plants from growing. These conditions are widespread in Southern Oregon into California, where this soil reaches the surface it produces zones of very specialized plants- they LOVE the harsh conditions and poor nutrients and tolerate the toxic elements. It can be quite a transition in plant communities from normal soil to serpentine- in just a few steps. This lovely annual sunflower though is EASY to grow in average to enriched soil- It handles just about everything so long as there is full sun. To 3′ tall and forming multiple spikes of 3″ electric yellow flowers with a contrasting black center. Amazing cut flower and if you remove flowers it will encourage more . Nice long stems for summer bouquets- they appear floppy but are in fact wiry and stiff- perfect for arranging. And a pollinator madhouse. Blooms June- October- one of our longest blooming native annuals. Forms a multibranched plant with shining flowers sticking out in all directions. Light consistent irrigation in summer. Makes a fantastic hedge of flowers. Re-seeds in open disturbed sites. Moderate deer resistance. Easy to grow. Oregon native plant.
Helichrysum thianshanicum
Useful and tough shrub that is the whitest gray that you can imagine. Evergreen plant that forms a rounded shrub to 2′ x 3′. In summer tall spikes carry umbels of striking soft yellow flowers. Very pretty and attractive to a host of pollinators. Adapted to the absolutely poorest soils and thrives without any appreciable irrigation. It may be cut back hard after flowering for a more compact plant. First rate foliage plant for contrast that does not rat out or go funky as older Lavender plants can. Extremely cold hardy and drought adapted.In fact this exotic competes very well with invasive weeds and no water landscapes. Native to Mongolia. Excellent plant for winter containers.
