Description

Wisteria frutescens, commonly called American wisteria, is a counterclockwise twining deciduous woody vine that grows to 40’ or more. It is native primarily to moist thickets, swampy woods, pond peripheries and stream borders from Virginia to Illinois south to Florida and Texas. Fragrant, pea-like, lilac-purple flowers in drooping racemes to 6” long bloom in April-May after the leaves emerge but before they fully develop. Limited additional summer bloom may occur. Flowers give way to narrow, flattened, smooth seed pods (to 5” long) which ripen in summer. Pods typically split open in fall. The compound, odd-pinnate leaves (each leaf typically with 9-15 lance-shaped leaflets) are deep green. American wisteria is not as aggressive a spreader as Wisteria sinensis (Chinese wisteria). Both Wisteria frutescens (American wisteria) and Wisteria sinensis (Chinese wisteria) twine in a counterclockwise direction but Wisteria floribunda (Japanese wisteria) twines clockwise.

It is best grown in slightly acidic, humusy, moderately fertile, moist, well-drained soils in full sun. Full sun is needed for best flowering. The vines may produce flowers by the second or third year after planting, but it may take longer. Vines need regular pruning(s) in order to control the size and shape of the plant and to encourage flowering. Consult a pruning guide for specifics on the initial training of vines and the types of pruning that can or should be done for these plants. An application of fertilizer in early spring can also help stimulate flowering. Choose growing sites wisely because plants dislike being transplanted.

Insects, Diseases, or Other Plant Problems: Although susceptible to a number of foliage-chewing insects and fungal diseases, none are significant. There are a number of reasons that vines may fail to flower including frost damage to flower buds in winter, too much shade, plants too young (especially seed grown ones), improper pruning or overfertilization.
