About

Wisteria floribunda, common name Japanese wisteria (藤, fuji), is a species of flowering plant in the family Fabaceae, native to Japan. (Wisteriopsis japonica, synonym Wisteria japonica, is a different species.) Growing to 9 m (30 ft), Wisteria floribunda is a woody, deciduous twining climber. It was first brought from Japan to the United States in the 1830s. It is a common subject for bonsai, along with Wisteria sinensis (Chinese wisteria).

Japanese wisteria sports the longest flower racemes of any wisteria; Some of those cultivars can reach 2 m (7 ft) in length. These racemes burst into clustered white, pink, violet, or blue flowers in early- to mid-spring. The flowers carry a fragrance similar to that of grapes. The early flowering time of Japanese wisteria can cause problems in temperate climates, where early frosts can destroy the coming years' flowers.
