Wisteria sinensis
vineZones 5–9Vigorous, long-lived vine with spectacular cascading clusters of fragrant purple or white flowers in spring. Requires sturdy support and firm pruning to control.
Fragrant flower clusters can reach 12 inches long. Support heavy bloom weight on arbors and pergolas.
Cut back all new whippy growth to 6 inches (5-6 leaves) from the main framework. This controls size and encourages flower buds.
Pull or cut suckers emerging from the ground away from the main trunk.
Shorten summer-pruned shoots further to 2-3 buds. These stubby spurs produce next spring's flowers.
