Ampelopsis brevipedunculata, still spreading in the Eastern United States
Ampelopsis brevipedunculata (Vitaceae), also known as porcelainberry, is a deciduous, woody, perennial vine that resembles American species of Vitis. The plant is native to Japan and North China and is present in the United States. There is no confirmation of its presence in Canada. This plant can be moved with trade of ornamental plants and easily escapes cultivation. Seeds may be dispersed by birds, other small animals, or water. A. brevipedunculata can be easily misidentified with wild Vitis, and has a negative impact on the natural environment. A. brevipedunculata is a vigorous invader of open and partially shaded habitats. As a fast grower it quickly spreads over other vegetation, shading them out and reducing native plant diversity in the area. In Massachusetts, A. brevipedunculata is one of the 140 invasive plant species which are now banned from entering the state.
