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.
Mules Ears are rare in cultivation. These cheery bold perennials make the transition of our wild flowers from spring into real summer. So named for its long leaves it forms very permanent spreading colonies in clay soils in habitat. The brilliant yellow sun flower blossoms rise up on sturdy stems directly from the ground. Each ebullient large flower is about 4″ across. Blooms appear from late April to early June. This plant usually finishes blooming just as summer drought commences. Its a memorable sight in wild meadows where it blooms simultaneously with native Rosa nutkana and Farewell to spring (Clarkia amoena var. lindleyi) and Giant blue eyed mary (Collinsia grandiflora). Wonderful cut flower and immediate and popular pollinator perennial. This plant was once very common in the Willamette Valley but civilization has immensely shrunk its native range. Good, long lived garden plant that goes summer dormant quickly after blooming has ended. The leaves turn gray and brittle and can easily be removed then. Give it a summer rest w/ little to no summer water once established. Full sun to very light shade. Water to establish its first season then none in subsequent years. Fun to grow and LONG lived. To 14″ in bloom forming a plant several feet across. Moderate deer resistance. Native to the Portland city limits. Oregon native plant
Adorable and rugged little dwarf Yucca from southern Utah. Tight round quills are decorated with filaments on the leaf edges. Not a friendly guy and very slow growing. Forming spheres of spikes to 1′ across and multiplying to produce colonies with pups. Full sun and very well drained soil of average to poor fertility. Requires excellent air circulation- no crowding. Plants that are smooshed with little air circulation protest heavily and it then takes a while for recovery. Open and free in rock garden conditions produces the happiest plants. At home nestled with boulders or as a finer texture element with Agaves. In time it produces adorable and conical shaped hoods of flowers- a gnome wedding. Excellent in containers- open, well drained containers. Light summer water during hot weather seems to speed growth. Locate away from paths. Owwie. Strongly deer and rabbit resistant.
Beaked Yucca does fantastically well in our climate and is one of the Yucca species that will form a dramatic trunk. Blue thin leaves radiate out in a perfectly round orb. Slowly rises to 8′ tall in our climate. Full hot all day sun in a warm position. Very well drained soil with light summer water during the hottest stretches to encourage growth. Occasionally, with age 4′ spikes appear holding large trusses of ivory flowers. Perfectly hardy to cold, way below 0ºF. Avoid cold wet sites- to really do well it needs heat and exposure. Not prone to bacterial leaf blight that affects other Yucca species. Good air circulation. Lives happily in large containers for eons. Focal point in many of the best gardens in our region. High deer resistance. Evergreen.
