Wisteria sinensis (Chinese Wisteria) is a woody, deciduous, perennial climbing vine in the genus Wisteria, native to China in the provinces of Guangxi, Guizhou, Hebei, Henan, Hubei, Shaanxi, and Yunnan. While this plant is a climbing vine, it can be trained into a tree-like shape, usually with a wavy trunk and a flattened top.
Wisteria is noted primarily for the beauty and perfume of its showy, deliciously fragrant flowers. Its rapid rate of growth makes it a good candidate when fast coverage is desirable.
It grows to a height of 25 feet or more and has flower clusters six inches to a foot in length, which open before the foliage has expanded. Individual flowers in the clusters open all at once for a very showy display. Flowers are violet-blue and slightly fragrant. Plants are most showy from early to mid-May in most seasons.
In order to bloom well, wisteria require full sun (six or more hours of direct sun per day) and a deep, moderately fertile, moist soil that does not dry out excessively. They will adapt to most soils, though they prefer a neutral to slightly acid soil pH of 6.0-7.0 for best results. Some type of support will be necessary as mature plants can be quite heavy.
