Ampelopsis brevipedunculata (Maxim.) Trautv.
Grape family (Vitaceae)
Origin: China, Korea, Japan and Russian Far East
Porcelainberry, also called amur peppervine, was originally cultivated as a bedding and landscape plant. In spite of its acknowledged invasiveness, it is still widely used and promoted in the horticultural trade.
Distribution and Habitat
Porcelainberry occurs from Wisconsin & Iowa to New Hampshire & south to Georgia and has been reported to be invasive in natural areas in at least ten states from Massachusetts to Virginia. It grows well in most soils, especially forest edges, pond margins, stream banks, thickets, and waste places, where there is full sunlight to partial shade, and where it is not permanently wet. It appears to be less tolerant of heavily shaded areas, such as that found in mature forest interiors. The seeds germinate readily in the soil after natural or human disturbance.
Porcelainberry is a vigorous invader of open and wooded habitats where it shades out native shrubs and young trees. As it spreads, it climbs over and blankets existing plants and weakens and kills them by blocking sunlight.

Description and Biology
Prevention and Control
Do not plant porcelainberry. Birds are attracted to the fruits and will easily spread it far and wide. Once established it can be difficult to control due to the vigorous root system. Pull young vines up by hand anytime and try to remove the rootstock. Apply systemic herbicides like glyphosate and triclopyr to cut stems or leaves to kill entire plants including the roots (see Control Options).
