Wisteria sinensis
Chinese Wisteria

Tolerant of widely different conditions once established, but this plant does not like being transplanted and establishment is sometimes slow. Once established, though, can even become invasive. Can be pruned as a standard, or pruned nearly to the ground to rejuvenate. Prune after flowering to 6" of main branch, and if pruned later, avoid removing the fatter flower buds that develop later. Needs a strong support structure. Use plants propagated vegetatively from heavy-flowering clones, as much variation exists in flowering. May take 7 years to flower.
