What does Wisteria look like?

Wisteria vines climb by wrapping their woody stems around supports, reaching up to 20 meters high and spreading 10 meters wide. The leaves are long and divided into many leaflets. Its flowers hang in drooping clusters, called racemes, which can be very long—up to 2 meters in some Japanese varieties. The flowers are usually white, lilac, purple, or pink, and many have a sweet, musky scent. After flowering, wisteria produces seed pods similar to those of other legumes.

Where does Wisteria come from?

Wisteria is native to East Asia—China, Japan, Korea, and Vietnam—as well as parts of North America, including the eastern United States and southern Canada, and north of Iran. The genus was named in Philadelphia in 1818 by Thomas Nuttall, in memory of Caspar Wistar. Wisteria was introduced to Europe in the 19th century and quickly became a popular ornamental plant. Its name is sometimes spelled 'wistaria', and in several European languages, it is known by variants of its former genus name, Glycine.

When and how Wisteria blooms

Wisteria blooms in spring in Asian species and in summer in American species. It prefers fertile, moist, well-drained soil and full sun, but can grow in poorer soils. It is usually grown from cuttings or grafts, as plants grown from seed may take many years to flower. Wisteria needs strong support, such as a pergola or wall, as mature plants become very heavy. Pruning helps control its size and encourages flowering.

How Wisteria is used

Wisteria is mainly grown as an ornamental vine in gardens, admired for its abundant, fragrant flowers. Some varieties of wisteria are edible if prepared correctly, but all parts contain a toxic compound called wisterin, and seeds are especially dangerous if eaten. In Japan, wisteria has been a popular symbol in family crests and art. In the United States, some species are considered invasive.

Kinds of Wisteria

There are four accepted species of wisteria. W. floribunda (Japanese wisteria) is known for its very long flower clusters, while W. sinensis (Chinese wisteria) is valued for its hardiness and shorter racemes. W. frutescens (American wisteria) has the shortest flower clusters. Many cultivars exist, especially of Japanese wisteria, with a range of flower colors and raceme lengths.

What Wisteria means

Wisteria is a traditional motif in Japanese family crests, especially those of the Fujiwara clan, and appears in art, dance, and design. The plant symbolizes longevity and fertility in Japan. In the West, wisteria has been used in decorative arts, such as tiles and stained glass. Wisteria is also grown in national collections in the United Kingdom.
