Kudzu is a semi-woody perennial vine that is invasive to North America. Capable of growing one foot per day, this invasive vine quickly engulfs large areas of trees, shrubs, ground vegetation, and buildings with a blanket-like covering of leaves and stems. Kudzu is challenging to control due to its extensive root system and its ability to form new plants from nodes on the stem. However, eradication can often be achieved with multiple years of management. Without management, Kudzu can spread rapidly and outcompete native plant species. This can lead to habitat loss and disrupt food chains for animals that rely solely on native species. Masses of vines can conceal potentially dangerous hazards, limit access to areas, and cause trees, power lines, or structures to fall under the weight of the plant.
Identification
Kudzu leaves consist of three leaflets that are each 3-8 inches long with up to three lobes. The leaf stem is hairy and 3-8 inches long. The vines are yellow green with bristly orange hairs when young. As they age, the vines turn brown and woody. In the late summer, kudzu plants flower with clusters of red, purple, or pink petals that smell like grapes. This flower will turn into a brown, flat, hairy seed pod up to 5 inches long.
Where Is Kudzu Located?
In New York, kudzu has been found on Long Island and in New York City and the Hudson Valley. Infestations are mainly present where kudzu was originally planted (e.g., on steep slopes and along railways and roadsides). It has also been found in disturbed areas — including vacant lots, industrial areas, and backyards — where it was most likely brought in through infested soil.
