Evergreen Wisteria is a woody vine with glossy leathery leaves. Unlike its cousin, the traditional Chinese wisteria , it is not invasive, although it is a vigorous sturdy vine. It needs a strong support such as a pergola or metal arch. The deep burgundy-purple blooms are very fragrant and it blooms summer through fall. It can reach 15-20 feet and should be spaced 6′ apart. Deadheading isn’t necessary but can encourage more blooms. It’s cold hardy to 20 degrees F., and should it go through a freeze, will return from the root. It prefers full sun but a half day is fine as well. As with all vigorous vines, you may want to heed the old axiom, “Never let your vine grow higher than your ladder can reach”!
