Japanese wisteria

Wisteria floribunda

wis-TEER-ee-ah floor-ih-BUN-dah Audio
Wisteria floribunda

Dramatic clusters of blue-violet to red-violet flowers with an intoxicating fragrance grace this vigorous twining climber. Its springtime cascading flower clusters can grow to 3 feet long or more in some cultivars. Blooms typically open first at the base and last at the tip of each cluster. Trunk diameter can reach 7 to 8 inches after 20 years, and the plant can climb to 35 or more feet in height, though its size is easily contolled by pruning.

CareProvide rich, well-drained soil with plenty of space. Wisteria needs strong support and can be trained as a tree, vertically on a wall or arbor, or horizontally on the ground. Growth can be restricted to a few limbs or allowed to spread vigorously to completely cover a wall. Early blooms can be damaged by freezing temperatures. Prune as needed when growth is active, but ideally in early, mid- and late summer. Can be difficult to get to bloom.

PropagationNot practical for most home gardeners.

ProblemsDieback, crown gall, leaf spots, viral diseases, Japanese beetles, aphids, leaf miners, scale insects, and mealybugs.

    I moved into a house with a wisteria already growing on the house wall. Because it was so unruly and we needed to paint the house, it was drastically pruned. It took about 3 years then to bloom again. Now it is fine, with fragrant, foot-long racimes of blue-violet flowers that bloom three times each summer: once before the leaves, and the second two times after the leaves. It sets no seed pods at all. Does anyone have an idea what kind of wisteria this may be?

    This part of the world has Leeds Castle which has a 400year old Wisteria and a garden with colourful bulbs to die for, this time of year.
