Porcelain-berry is a woody, perennial vine that closely resembles native grape (Vitis). It can be distinguished by its branched tendrils, while native grape has unbranched tendrils. Porcelain-berry is capable of growing over 20 feet in height and can easily smother lower growing trees and shrubs. Leaves are simple, alternate, and range from slightly lobed to deeply dissected. The leaf margins have distinct coarse teeth. During mid-summer, porcelain-berry produces clusters of small greenish-white flowers. Fruits are small, round berries that range in color from yellow to blue to purple.

Porcelain-berry prefers moist soil and thrives in a wide range of light availability. It is commonly found along forest edges, pond margins, stream banks, right-of-ways and waste places.
Threats & Impacts:
Thick mats of vegetation formed by porcelain-berry can easily shade out native trees and shrubs. It is able to spread quickly over long distances via bird and animal dispersed seeds.
Small infestations and young plants can be controlled by hand-pulling. Larger infestations can be treated via cut stump or foliar spray with glyphosate or triclopyr based herbicides.
