Oval (occasionally lobed) green leaves. Grows 3-6′ high and wide. Z3.
Rubus spectabilis ‘Olympic Double’ (syn. ‘Flore Pleno’) – This cultivar of Salmonberry features large double blooms (about 2″ wide) of magenta-rose that much resemble little dahlias. It is a suckering deciduous shrub that forms a dense colony covered with bright green trifoliate leaves. Attracts hummingbirds. Discovered in Bremerton, Washington. Grows 6-8′ high by 8′ wide. Zone 5.
Mahonia repens – Creeping Oregon Grape is an excellent tall evergreen groundcover (for part sun) naturally found in higher elevations. The green holly-like leaves occasionally turn bronze in colder weather. Produces bright yellow flower clusters in spring followed by tart dark purple-blue berries that make a good jelly. Drought tolerant. Grows 18-24″ high by 2-3′ wide. Zone 5.
Spiraea douglasii – Hardhack is a vigorous deciduous shrub commonly found in wet swampy areas with full sun. It forms large thickets with simple green leaves (toothed) and produces fluffy rose-pink flowers in summer that fade to brown and persist. Named after the Scottish botanist David Douglas. Attracts butterflies. Grows 4 to 8′ high and wide. Hardy to zone 5.
