Wisterias are durable and beautiful vines, surviving drought with little to no added water and blooming spectacularly each spring. One Wisteria, in particular, stands from the others, because it repeats its bloom through summer. The spring bloom itself is enough to want the vine, but the added benefit of repeat (smaller) blooms in summer gives Cooke’s Special Purple Wisteria an appeal like no other. Why not shade a patio with this beautiful bloomer?
Cooke’s Purple Wisteria is our favorite Wisteria; we sell more of this variety than any other. We have a couple of them planted beside the greenhouse here at the nursery. Neither of which suffered through the drought despite receiving very little water.
Each March or April these wisterias crack color and unfurl slowly to provide a lengthy display lasting as long as a month . . . blossoms unfurl first, followed by lacy leaves. Then as summer heats up additional blossoms pepper the vine occasionally through fall.
Wisteria is grown most often as a vine but can be trained into a small tree. It is a rampant grower and can reach out 20-30 feet. As a vine, it must be supported by a heavy structure, such as a built-in wood arbor or pergola. If grown as a self-supporting tree, start out training it up a pair of lodgepole stakes. It will normally be kept at about 15′ high and wide.
Wisteria can grow in full sun or morning sun and they bloom best if they suffer a bit of drought. Wisterias planted near a lawn will not bloom as well. Water regularly the first 1 to 2 years to establish.
We usually carry Cooke’s Wisteria in 5-gallon and 15-gallon sizes, both as a vine and also as a small tree. Select your wisteria early, as the supply diminishes as the season and the blossoms unfold.
