a species of flowering plant in the rose (Rosaceae) family, related to the blackberry
In the eastern and southern United States, several native species, especially the northern dewberry (Rubus flagellaris), the bristly dewberry (R. hispidus), and the southern dewberry (R. trivialis), produce excellent fruits. The European dewberry (R. caesius) has blue-tinged fruits that are generally less palatable.
