Springbank Clover. Fascinating perennial clover that was once widespread in wet areas of the Willamette Valley and is now found in restricted sites there but is much more prevalent on the coast and east of the Cascades. A pretty spreading spring wildflower with heads of brilliant magenta/purple flowers. Mainly in spring but also in summer if wet. To 4″ tall it can be up to 2′ wide in favorable conditions. Though mostly restricted to seeps and wet areas now it once made life under native white oaks and there indigenous people would use it as a food source. The creeping green stems root where they touch the ground. Stems were harvested and steamed as a vegetable and they replanted as they harvested the remaining stems ensuring another crop. Not a long lived perennial 3-5 years but it sets copious seed. Wet sites in moisture retentive soil. Mainly riparian in habitat. It can dry considerably in summer and still thrive. But regular water is what it wants. Fun plant to grow that has lost a LOT of its native range. In habitat it is best seen on the wet cliffs adjacent to the beach. Great pollinator plant. Easily overwhelmed by invasive exotics. Oregon native plant.
One of Oregon’s greatest wildflowers. This native of the Siskiyous and the SW part of the state makes an outstanding garden plant. Ours are divisions from well marked leaves and flowers with a deep maroon/black hue. To 18″ tall in bloom it responds readily to rich, humus filled soil with regular summer water. In very dry conditions it will go happily summer dormant. And it usually does anyway by the end of the hot season. The black and green leaves are dramatic but a great collar to the tall upright dark flowers. Blooms appear in Portland in April/May and last for weeks. Part shade to shade- avoid blasting hot sun- it will grow in sun but go dormant very quickly. Roots very deep into the ground- difficult to move once established so pick its home carefully. Multiplies into a substantial patch with good care. One of our favorite native wildflowers. Limited quantities. Oregon native plant.
Fool’s Onion, though this close relative of Brodiaea is easy to tell apart from Allium as the leaves and stem have no onion odor. A sunny native perennial bulb that forms colonies of white in May-July in meadows, glens, and swales. To 15″ tall in bloom but usually shorter the leaves emerge in mid winter and persist until summer drought. About that time the flowers erupt into clusters of white flowers. Great native bulb for naturalizing, Water if planting from a pot, otherwise it requires only what falls from the sky with a distinct dry period in summer. Associated plants are Ranunculus occidentalis- Western Buttercup, and Brodiaea elegans- Cluster lily, and Plectritis congesta- Sea Blush. Native in clay soils that dry completely in summer. Goes very neatly dormant in summer- nothing is left. Excellent in rock garden conditions. Full sun to very light shade. Moderate deer resistance. Native though out western Oregon. Sweet cutflower Very good for butterflies as well. This plant once occupied large areas of the Willamette Valley, that territory has shrunk considerably. Oregon native plant.
Evergreen huckleberry is a fantastic native broadleaf shrub. It is well adapted to shady sites and will accept full sun with regular irrigation. Well established shrubs require less water. Rich, humusy woodland soil is its favorite haunt and it will grow moderately fast to a rounded outline of 8′ tall and 6′ wide. The new growth is a beautiful salmon pink before changing to deep green. In spring and early summer small white urn shaped flowers are pretty and transform into tasty black fruits in autumn. Amazing in muffins, pies.It has an interesting natural distribution along the immediate coast in most of Oregon but veering inland at Douglas County to almost the Cascade foothills. In Puget Sound it seems to be most prominent within sight of salt water. Easy to grow good garden plant. Oregon native plant.
Rare perennial Siskiyou Inside-out-Flower is a much more drought tolerant version of our locally native Vancouveria hexandra (Inside out flower). This yellow flowered species tolerates extreme dry shade and colonizes even compacted dry soils to create a handsome ground cover. The delicate looking interestingly shaped leaves create a soft mound of shapes in cool green and edged slightly in red. In April-June 20″ wiry spikes suspend small downward pointing flowers- they appear to float above the foliage reminding me of a group of fireflies. (Wish we had those). Mostly evergreen if temperatures stay above about 15ºF. Basically this is our version of Epimedium (to which it is related) but with more tolerance for summer drought. To 8″ tall and spreading to several feet wide in richer, moisture retentive soil. Light summer water increases growth. This is an extraordinarily elegant native that should find a happy home in gardens too. Part shade to full shade. Not bothered by pests. Excellent perennial under large shrubs or within tree roots. In the wild it is the understory plant to Arctostaphylos, Rhododendron, Vaccinium, Notholithocarpus densiflorus var. echinoides. Associate perennials were Oxalis oreganus and Mianthemum as well as viola semperivrens- Redwood violet. Easy community to replicate in your garden. Oregon native plant.
Inside-Out-Flower is a commonly seen terrestrial component in dry to moderately moist woodlands in our region. The duck foot shaped leaves are conspicuous and pretty and in late spring to mid-summer a continuous supply of dainty downward pointing white flowers. Spreads in gardens very well in enriched soil with regular summer water where it will quickly assume the role of an intertwining ground cover. Winter deciduous- un-like its close and much more drought adapted relative Vancouveria chrysantha (Yellow inside-out-flower, Siskiyou Vancouveria). This perennial is perfect for life among shrubs or mixing with other woodland perennials in part shade to shade. Adapts well to garden culture and thrives on regular summer irrigation. Locally native in the city of Portland. To 10″ tall and spreading. Some deer resistance. Oregon native plant.
Oregon Viburnum or Western Way Faring tree is a moderate to large native deciduous shrub. It stretches a little bit into W. Washington where it is rare but its primary populations are in western Oregon and south into N. California. Its found in moist to dry woods often on the margin where its can get at least half a day sun. It also thrives only much larger and lankier in outline in the shade. It easily tolerates winter inundation but is found on well developed soils in upland situations as well. Its common associates in the wild are Oregon white oak/Quercus garryana, Oregon Ash/Fraxinus latifolius, Cornus stolonifera. Leaves are round, glossy and scalloped and are very handsome on a well proportioned fountain shaped shrub. Shorter in full sun, taller in shade. This plant needs just a modicum of light watering for its first year and once it is thoroughly established you can set it free. In late spring off white cymes of flowers have the fragrance to me of raw potatoes. We had a large specimen of this shrub in our back 40 where I grew up near Eugene. In certain years it can produce quite a fall show with orange/red tinted leaves and translucent blue fruits. Blooms on wood from the previous year. Prune if needed AFTER blooming has ended. June. To 5′ tall in the sun to much taller in shade. Protect young plants from deer. Oregon native plant.
Canary violet or upland Violet has many subspecies in the PNW and west in general. This is our own Willamette Valley form of this intriguing handsome perennial. Large spoon shaped leaves have an underside with conspicuous hairs. The top of the leaf is glossier. In April-May bright yellow flowers appear. The bottom petal has conspicuous black whiskers. In our region this violet is local in the most undisturbed sites but it shows very good persistence in competition with non-native introduced grasses. My experience is that it favors rocky and scree sites that remain somewhat cool- for instance the north side of a steep slope. To 6″ tall and forming expanding plants. Winter deciduous. Arrives early in spring and can go summer dormant with high heat. Excellent planted in fall or winter and left to its own devices. Average to enriched soil yields the best results. This is one of the showiest violets native to the Willamette Valley. Fairly long lived. Little deer resistance. Some associated plants are Olysinium douglasii, Sedum spathulifolium, Dodecatheon hendersonii. Oregon native plant.
Yerba de Selva or whipple vine, a wonderful small scale evergreen native ground cover. Related to Hydrangeas but this trailer is actually very aromatic with a sweet penetrating aroma if you disturb the foliage. In late spring clouds of small white flowers have the same perfume. Scrambling plant to about 8″ tall and 2′ wide. Full sun to considerable shade. From Portland south this is a common understory component of the herb field. It grew happily in our back 40 where I grew up. There it made pretty scrambling patches between Vancouveria, snow berry and hairy honeysuckle. Often you would see our native columbine ( Aquilegia formosa) as an associate. Its very drought adapted when established but it improves with a few soaks over summer- never perpetually wet and never hot and wet. Otherwise an easy native that should be grown a lot more. Just the fragrance of the foliage endears it to me. For use as a small scale ground cover plant on 10″ centers. It will also gracefully trail over rockeries and walls. Butterflies adore the flowers. Competes well with invasives. Some deer resistance. It may be cut back in early spring to refresh. Once native in the Portland city limits. Oregon native plant.
Our native Giant Chain Fern that occupies specific spots in seeps randomly from CA to BC. Large pendant and trailing 3′ long glossy fronds form huge rosettes. Usually occupying permanently wet seeps on shady hillsides in cool places. The entire plant may be up to 5′ across. Evergreen but it benefits greatly from some early spring tidying of spent and aging old leaves. Part shade to shade in rich well drained soil with regular consistent moisture for the best look. Highly deer resistant. We’re honored to grow this, one of our most spectacular native ferns. Oregon native plant.
