Chinese wisteria (Wisteria sinensis) is a deciduous perennial vine with a twining growth habit. Like all members of the wisteria group, Chinese wisteria is a stunning bloomer. From May to June, it bears large, drooping clusters of fragrant flowers that are typically a bluish-purple. The vine is a vigorous climber that can grow to 25 feet. Trellises and other supports must be sturdy to hold the plant's weight. Chinese wisteria can take up to 20 years to mature enough to produce flowers. But it also tends to be very long-lasting, living up to 100 years.
