About the wisteria

Wisteria is a woody, twining vine that produces dramatic hanging clusters (racemes) of pea-like flowers before or as its leaves emerge. It’s powerful enough to damage weak structures and can take several years to begin blooming, but a well-grown wisteria is unforgettable. The seeds and pods are toxic.

Wisteria FAQs

Why won’t my wisteria bloom?

Common reasons are a plant that’s still too young, too much nitrogen fertilizer (which favors leaves), too little sun, or a lack of the proper twice-yearly pruning that encourages flower buds.

Is wisteria invasive?

Asian wisterias (Chinese and Japanese) are vigorous and can be invasive, overwhelming structures and other plants. American wisteria is a less aggressive alternative.

Is wisteria poisonous?

Yes. The seeds and pods of wisteria are toxic if eaten, so keep them away from children and pets, and site the plant with care.
