Facts About

Heart-leaved peppervine is a woody liana that hails from the southern states. In New England, it is only known from Connecticut, where it is considered a non-native introduction. Its heart-shaped leaves are much less lobed than those of its congener, Ampelopsis glandulosa; also, its twigs are less hairy. This member of the grape family produces pink to purplish fruits in late summer, but unlike grapes, they are not edible.
