- Description
-
Swamp dewberry is a native perennial shrub in the Rose (Rosaceae) family with branching woody vines and trailing stems up to 8' long. Rather than arching canes, dewberries produce trailing stems that creep along the ground. The stems can root at the tips forming new plants. It is commonly found in wetland areas, disturbed habitats, forest edges, meadows, fields, and swamps. In NC it is primarily found in the coastal plains and the mountains and is rare in the Piedmont. The stems easily root at the tips forming new plants.
The flowers of swamp dewberry are visited primarily by bees, including both long-tongued and short-tongued bees. The fruits are eaten by many species of songbirds and mammals. The summer berries have a sour flavor and the plant is generally not cultivated.
Diseases, Insects, and Other Plant Problems: Potential insect problems are cane-boring beetles, leaf beetles, stink bugs, aphids, leafhoppers, treehoppers, katydids, walkingsticks, thrips, the larvae of sawflies, and the larvae of many moths.
