Wisteria
Wisteria, or Wistaria, a woody, climbing vine grown for its showy flower clusters. There are about 10 species and several varieties, some native to Asia and others to North America. Popular species are the Japanese wisteria and the Chinese wisteria. Depending on the species or variety, the flowers may be white, lilac, purple, or bluish. The flower clusters can grow three feet (1 m) or more in length. Wisterias are quite hardy and will grow in ordinary garden soil in a sunny location. They are long-lived vines and can climb to a height of 20 to 30 feet (6 to 9 m). All parts of the plant contain a poisonous alkaloid.
Wisterias make up the genus Wisteria of the pea family, Leguminosae. The Japanese wisteria is W. floribunda; the Chinese, W. sinensis.
