In the southern U.S., it's a sure sign of spring when the sweet scent of wisteria (wisteria futescens) wafts through the air. Wisteria's huge flowers resemble grape-like clusters, and in some varieties, the clusters can grow up to 3 feet (91.4 centimeters) in length. The purple-or-white hued petals of the wisteria will drop within a few days, so it's best to pause, relax under the lovely shade and enjoy this beauty while you can.
Gardeners love its delicate perfume in the spring, but the rest of year, this vigorous vine seems to have a mind of its own. Wisteria loves to climb and wander, adding privacy and shade to pergolas or arbors. It can also be trained on a trellis, or grown horizontally on the ground.
