Japanese and Chinese Wisteria
Wisteria floribunda and Wisteria sinensis
Japanese and Chinese Wisteria (Asian Wisterias) are perennial woody vines that have been planted extensively for their ornamental flowers. But they escape gardens and establish in natural areas, displacing native vegetation. Wisterias kill mature trees by shading and strangling them with their thick, heavy vines. Asian Wisterias are banned from sale, transport, and planting effective October 2024.
How to Control
Asian Wisterias reproduce from seeds in fuzzy pods, from stems touching the ground, and from any bit of root left on the ground. Cut vines must be bagged and disposed of so no portion of the plant touches the ground. After cutting at ground level, woody vines must be unwrapped from tree trunks or they will still girdle trees.
