Details
American bittersweet is a native woody and shrubby climber, growing over trees or fences. It has smooth thin leaves 2 to 4 inches long and about half as wide. The small greenish-white flowers are produced in June in short clusters. The fruit is a round, orange-yellow capsule that opens in autumn, disclosing the scarlet-colored seed pod. The seed capsules remain on the plant well into the cold season and provide food for birds in the winter. Fruits are eaten by songbirds, ruffed grouse, pheasants, bobwhite, and squirrel. Old fruits are eaten as survival foods by many birds and animals in late winter.
