Black raspberry is a native, deciduous perennial shrub in the Roseaceae family. It is common in the mountains, but scarce in the Piedmont and coastal plain of North Carolina. It can be found specifically along roadsides, in woodlands, and disturbed areas. If planted in sites that are sunny and dry, the fruit may not develop properly without adequate rain. The canes also fail to set fruit if there is too much shade. The canes start out growing erect to about 6 feet long in the first year, but eventually arch sideways and down and can reach the ground. Rubus occidentalis prefers partial sun and moist, highly organic soil. This plant is heat tolerant.
Black raspberry is moderately resistant to damage from deer. It provides excellent cover year round. Butterflies and other insects are attracted to the blooms and the fruits are eaten by songbirds, small mammals, foxes, raccoons, and black bears. During the winter, birds and small mammals eat the seeds left from rotted fruit. White-tailed deer and rabbits browse the leaves.
Diseases, Insects, and Other Plant Problems: Other than honey fungus, to which most Rubus species are susceptible, there are few problems.
