- Deciduous shrub-vine, to 6 ft (~ 2m) arching or trailing, stems round, armed (recurved spines or prickles), old stems light bluish due to a waxy coating over red bark. Leaves alternate, compound, 3-5(7) ovate leaflets, serrate and doubly serrate or coarsely toothed, mostly green above, much paler below, covered with soft (whitish) down. Prickles found on stems, petioles, and sometimes leaf veins. The stems (canes) of Rubus are often biennial, the new stems in their first year are non-flowering (they are called, primocanes); flowers form on lateral shoots on these canes in the second season (now the canes are called floricanes). Flowers are white to pink, 2-3 cm across, borne singly or in small, 3-7, clusters (corymbs). Fruit red, dark purple, or black aggregate of druplets, about 1 cm wide, sweet and mild-flavored.
- Sun or shade. Seems to grow in sand, clay, and soils with poor drainage and seasonal flooding.
- Hardy to USDA Zone 5 Native from southern Alaska southward to British Columbia, Washington, Oregon, and California, east to Utah and Montana. Introduced to commerce in about 1829 by David Douglas.
