FAMILY SCIENTIFIC NAME
Synonyms: Ampelopsis heterophylla (Thunb.) Sieb. & Zucc., Ampelopsis brevipedunculata var. maximowiczii (Regel) Rehd. (a variety that is just as invasive with deeper lobes).
Ampelopsis brevipedunculata is a tendril-bearing perennial vine that can grow 3-6 m (10-20 ft.) high or more. The alternate leaves are cordate-ovate and are 5-10 cm (2-4 in.) across. The young twigs, petioles and the undersides of the leaves are hairy. The leaves are slightly 3-lobed, sometimes 5-lobed and can be cleft. They are short-acuminate and crenate-dentate with apiculate points. The green flowers, arranged in cymes, are dense and small and appear in July-August. The fruit appear in September are spherical and 6-8 mm (0.25-0.3 in.) in size. They are hard berries that can vary in color from yellow to lilac to green, and most often end up a sky blue. These berries can be marbled and a variety of colors can be found in one cluster of fruit.

The seeds of Ampelopsis brevipedunculata are bird dispersed, though there has been some indication of water acting as a secondary method of dispersal.
Ampelopsis brevipedunculata is native to Japan and North China. Its current range in the U. S. is from New Hampshire to Georgia and west to Wisconsin. In New England it is present in New Hampshire, Massachusetts, Connecticut and Rhode Island.
HISTORY OF INTRODUCTION IN NEW ENGLAND
Ampelopsis brevipedunculata was introduced into cultivation in 1870 on the grounds of eastern estates to be used as a bedding and screening plant. The variety 'Elegans' was introduced before 1847. Thus, it was most likely introduced into New England by direct planting, or possibly through bird dispersal.
HABITATS IN NEW ENGLAND
Abandoned Field, Early Successional Forest, Edge, Pasture, Planted Forest, Railroad Right-of-Way, Roadside, Utility Right-of-Way, Vacant Lot, Yard or Garden. Ampelopsis brevipedunculata prefers moist soils and partial sun. It grows well along stream banks and thickets. It can also be found along highway shoulders, railroad beds, shorelines, in fields, hedges or at the edges of forests.
Because it is a vine, Ampelopsis brevipedunculata has the ability to grow up and smother native vegetation. The extra weight of this vine on the underlying plant makes it more susceptible to wind and ice damage. Ampelopsis brevipedunculata grows rapidly and is difficult to control. The fruit can float, so water can disperse these plants long distances. The seeds are known to have a high germination rate, aiding the establishment of this plant.
