When comparing the different types of wisteria, the choice often boils down to aesthetics and availability. The two species of wisteria most commonly grown in the United States are Japanese wisteria and Chinese wisteria. These Asian imports have become the favorites of gardeners because of their showy flower clusters, intense fragrance, and the wide array of color options and cultivars available. However, they also are the most aggressive growers and are even considered invasive in some areas of the country.
If you are looking for a tamer form of wisteria, our native species (American wisteria and Kentucky wisteria) are great alternatives that offer the same lush beauty but are slower growing and less likely to overrun your garden. Unfortunately, these varieties can be difficult to find at local nurseries, but you can often purchase them from mail-order suppliers.
How do I tell the different species of wisteria apart?
Look at the direction the vines twist around their support structure. If they turn counterclockwise, you are growing Chinese wisteria or one of the American varieties. Japanese wisteria always grows clockwise. Also look at the seedpods. The pods of the Asian wisterias have velvety surfaces covered with a downy fuzz while the pods of native wisteria are smooth.
