    Chinese wisteria (Wisteria sinensis (Sims) DC) is a deciduous, perennial, leguminous woody vine that is invasive throughout much of the Eastern U.S. A related wisteria that invades the same range is Japanese wisteria (W. floribunda (Willd.) DC). It is difficult to distinguish Chinese from Japanese wisteria due to similar leaves, flowers, and probable hybridization. There are indications that hybrids of the two are the norm and not the exception (personal communications: Dr Jennifer Trusty, Auburn University). Interesting enough, Chinese wisteria twines clockwise (lower left ascending to upper right) while Japanese wisteria twines counter-clockwise, supposedly because of the well known north-south hemisphere differences in water draining and vine twining. This may be a remnant of continental drift after species differentiation in opposite hemispheres.
