Discussion North America is home to two beautiful native wisterias, but the Asian varieties have been much more widely planted. These exotics are said to be able to reach heights of 65 feet (20 m) and stem diameters of 15 inches (37.5 cm). They are rampant growers and have expanded beyond cultivation and into natural habitats in many areas. Chinese Wisteria and Japanese Wisteria are both considered noxious or invasive pest plants in many parts of the East.
