Wisteria Floribunda is a species of flowering plant in the pea family Fabaceae, native to Japan. It was brought from Japan to the United States in 1830's. Since then, it has become one of the most highly romanticized flowering garden plants. It is also a subject for bonsai, along with Wisteria sinensis (Chinese wisteria).
The flowering habit of Japanese wisteria is perhaps the most spectacular of the Wisteria family. It sports the longest flower racemes of any wisteria; they can reach nearly 2 feet in length. These racemes burst into great trails of clustered pink, violet, or blue flowers in early- to mid-spring. The flowers carry a distinctive fragrance similar to that of grapes. Japanese wisteria can grow over many supports via powerful clockwise-twining stems. The foliage consists of shiny, dark-green, pinnate compound leaves 5-12" in length.
Japanese wisteria prefers moist soils and full sun in USDA plant hardiness zones 5-9. The plant often lives over fifty years.
