American Wisteria is a woody, deciduous, perennial climbing vine, native to the wet forests and stream banks of the southeastern United States. American Wisteria can grow up to 15 m long over many supports via powerful clockwise-twining stems. It produces dense clusters of blue-purple, two-lipped, 2-cm-wide flowers on racemes 2-6 inches long in late spring to early summer. These are the smallest racemes produced by any member of the Wisteria family. This size of the racemes is considered small in comparison to some other more showy Wisteria species. Leaves are shiny, dark-green, pinnately compound, 4-12 inches in length. The leaves bear 9-15 oblong leaflets that are each 2-6 cm long. It also bears numerous poisonous, brown, bean-like seed pods 2-4 inches long that mature in summer and persist until winter.
