Wisteria frutescens 'Amethyst Falls'
Nursery Pro tip: Ask for the American type — it blooms in two years and won't pull down your pergola like the Chinese one. Prune hard after the spring bloom.
American wisteria 'Amethyst Falls' — a well-behaved native alternative to the Asian species, with fragrant purple flower clusters in spring and often again in summer, on a 15–25 ft vine that won't tear down your arbor. Choose this one; Chinese and Japanese wisteria are aggressive enough to lift shingles and strangle trees.
Full sun for the best bloom, part shade tolerated. Any drained soil. Needs a genuinely strong support — a substantial arbor, pergola or steel fence, never a downspout or a young tree.
Spring or fall. Hole twice the pot width, ball at grade, native soil, Root Stimulator, mulch. Tie the leaders in the direction you want.
Weekly the first two summers, then every week or two.
Little to none — nitrogen gives you a wall of leaves and no flowers. A high-phosphorus feeding in early spring if bloom is sparse.
Twice a year is the secret to flowers: cut the long whippy shoots back to five or six leaves in midsummer, then shorten those spurs again to two or three buds in winter. A wisteria that never blooms is nearly always one that's never pruned (or is too young — give it two or three years).
Seeds and pods are poisonous if eaten. Even the American species suckers and will run along a bed if you let it. Keep it off trees and gutters.
An arbor or pergola over a patio, or along a sturdy fence. Beautiful with Carolina jessamine for a longer spring.
