Facts About
River grape grows on riverbanks and in many other habitats. Its almost hairless, lustrous green, coarsely-toothed leaves and few tendrils distinguish it from other grapes (Vitis). Although the fruits produced by this species tend to be sour to human tastes even when ripe, they do provide food for many species of birds. Many specialist insects feed on the leaves, stems, and roots.
