General Description

Black raspberries are upright deciduous shrubs derived from the North American native Rubus occidentalis. The insignificant flowers produce edible black fruit in summer on blue-gray, prickly canes. There are many cultivars, selected for color, flavor, and harvest time. 'Cumberland' bears large, firm, glossy black berries noted for their outstanding flavor. Plants produce canes that mature their first year, bear fruit their second, and then die back.

Black raspberries prefer sun and well-drained, moderately fertile soil, and need a cold winter and gradual spring to produce the best fruit. Partial shade and a cool mulch may be required in hot-summer areas. Prune first-year canes back by a third and second-year canes to the ground in fall. 'Cumberland' makes a rewarding plant for the culinary garden, but is susceptible to anthracnose, rosette, and streak disease.
