Description
Wisteria vines climb by twining their stems either clockwise or counterclockwise round any available support. They can climb as high as 20 m above the ground and spread out 10 m laterally. The world's largest known Wisteria vine is in Sierra Madre, California, measuring more than 1 acre (0.40 ha) in size and weighing 250 tons, planted in 1894 of the Chinese lavender variety.
The leaves are alternate, 15 to 35 cm long, pinnate, with 9 to 19 leaflets. The flowers are produced in pendulous racemes 10 to 80 cm long, similar to those of the genus Laburnum, but are purple, violet, pink or white. There is no yellow on the leaves. Flowering is in the spring (just before or as the leaves open) in some Asian species, and in mid to late summer in the American species and W. japonica. The flowers of some species are fragrant, most notably Chinese Wisteria. The seeds are produced in pods similar to those of Laburnum, and, like the seeds of that genus, are poisonous.
Wisteria is an extremely hardy plant that is considered an invasive species in many parts of the U.S., especially the Southeast, due to its ability to overtake and choke out other native plant species.
I watch it grow all over the part of the country I live in. It is so lovely in the spring of the year. Evasive yes, pretty in the spring very defiantly, yes.
