- Wisteria floribunda is a deciduous, woody vine capable of growing to a height of 35 ft. (10.7 m). Stems can be up to 10 in. (25.4 cm) in diameter, with smooth, light gray to white bark. When looking down at the plant the vines twine around the host plant in a clockwise direction.
- Alternate, pinnately compound leaves (13-19 leaflets) are tapered at the tip with wavy edges. Leaflets are up to 12 in. (30 cm) in length.
- Lavender, pink or white flowers are fragrant, very showy and abundant and occur in dangling clusters in the spring. Flowers clusters are 9-20 in. (22.9-50.8 cm) long.
- Seeds are contained within brown, hairy, flattened, bean-like pods. Although seeds are viable, vegetative growth is the primary method of spread for this invasive.
- Ecological Threat
- Invasions often occur around previous plantings. Wisteria floribunda can displace native vegetation and kill trees and shrubs by girdling them. The vine has the ability to change the structure of a forest by killing trees and altering the light availability to the forest floor. A native of Japan, it was first introduced into North America around 1830 for ornamental purposes.
