Japanese wisteria Fabaceae Wisteria floribunda

Leaf:Alternate, pinnately compound, 9 to 15 ovate to lanceolate leaflets each 2 to 3 inches long, dark green above.
Flower:Very showy, purple or white (depending on cultivar) pea-like flowers, occurring in long hanging clusters, to 20 inches long, appearing with the leaves, flowers of one raceme opening from base to tip.
Fruit:Finely fuzzy, pea-like pods, 3 to 6 inches long, persistent.
Twig:Slender, light brown, raised circular leaf scar, appressed triangular light brown buds, and false terminal bud.
Bark:Smooth, gray-brown, and fluted. Trunk can be quite large for a vine; older specimens can reach a foot in diameter.
Form:A climbing twining vine, reaching up to 40 feet in height often covering trees and shrubs, twines clockwise.
Special Note: W. sinensis and W. floribunda readily hybridize to form W. xformosa, and most naturalized specimens in the southeast are likely this hybrid.
