Rubus spectabilis Pursh
Salmonberry, Salmon Raspberry
Rosaceae (Rose Family)
USDA Symbol: rusp
USDA Native Status: L48 (N), AK (N), CAN (N)
A thicket-forming shrub, usually 3-9 ft. tall, with erect to arching stems and trifoliate leaves. Stems are bristly below, less so above. The big, reddish-purple, solitary flowers appear before the pinnate, toothed foliage. The large, bright, showy petals surround a large cluster of stamens. An erect or sometimes leaning shrub with weakly armed stems, bright pink flowers, and yellow or salmon-red fruits that resemble a cultivated blackberry in all but color. The berry is raspberry-like and yellow to reddish.
Growing on moist, sunny slopes in the Cascades, Salmonberry can form impenetrable thickets. The juicy fruit, which looks like a yellow or orange blackberry, is a welcome trailside snack, though too bland for some tastes. Indians ate not only the berries but also the tender young shoots. Numerous birds and animals also feast on the fruits, which may be abundant in good years. The deep pink flowers are distinctive and may occur along with the fruits.

PropagationDescription: Propagation is easiest by cuttings or layering. Increase by seed is not as easy but is possible.
Seed Collection: Rubus fruits should be collected as soon as ripe to prevent losses to birds. The seeds can be extracted by macerating in water.
Seed Treatment: The hard, impermeable seed coat needs scarification. Both H2SO4 and sodium hypochlorite have been used. Scarification is sometimes followed by a complex combination of warm and cold stratification.
