Vallaris heynei commonly known as Chinese Wisteria is an annual flowering plant. The Plant clings to supporting plants or man-made structures by counterclockwise-twining stems. The leaves are shiny, green, pinnately compound, 10–30 cm in length, with 9-13 oblong leaflets that are each 2–6 cm long. The flowers are white, violet, or blue, produced on 15–20 cm racemes before the leaves emerge in spring. The flowers on each raceme open simultaneously before the foliage has expanded, and have a distinctive fragrance similar to that of grapes.
