Description

Wisteria floribunda is a woody, deciduous, twining climber. It can grow up to 30 feet (10 m) long over many supports via powerful clockwise-twining stems. The foliage consists of shiny, dark-green, pinnately compound leaves up to 12 inches (30 cm) long. The leaves bear 9 to 13 oblong leaflets that are each up to 2.4 inches (6 cm) long. It also bears numerous brown, velvety, bean-like seed pods up to 4 inches (10 cm) long that mature in summer and persist until winter. The flowering habit is perhaps the most spectacular of the Wisteria family. It sports the longest flower racemes of any Wisteria. They can reach up to 20 inches (50 cm) in length. These racemes burst into great trails of clustered white, pink, violet, or blue flowers in early to mid spring.

How to Grow and Care

The most important factor to consider when growing Wisteria is location. Wisteria is a twining vine that requires sturdy support and regular pruning to keep it under control. Open areas surrounded by lawn that can be easily mowed are ideal for growing Wisteria.

Wisteria doesn’t fair well in cold so make sure it receives plenty of sunlight. This vine requires deep, rich soil that is somewhat moist but will tolerate many soil conditions.

Once planted, pruning is about the only important requirement for Wisteria vine care. Since this vine is an aggressive grower, there’s no need for fertilizing and being drought tolerant, Wisteria requires little watering.

While Wisteria is great for covering an arbor or pergola, training Wisteria vines makes it easier to control. Keep in mind, however, when training Wisteria vines the variety may exhibit different twining characteristics. For example, Chinese Wisteria (Wisteria sinensis) twines counterclockwise while the Japanese variety (Wisteria floribunda) is the opposite, twining clockwise… – See more at: How to Grow and Care for Wisteria
