- 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, tight gray to white bark.
- 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.
