Notes:
There is also a variegated leaf form of this plant.

Fruit has been found to have particular patterns of pigments that make them especially attractive to birds (see M. Witty, A. Yard, J.L. Kinard and Ruth O. Adekunle, 2010. Ampelopsis brevipedunculata berries are simultaneously attractive to birds and repulsive to mammals. International Journal of Botany 6: 35-40.
