With the ability to climb over 15 feet in a growing season, porcelain berry easily creates mats of thick twining vines which smother native vegetation. If established in residential or commercial areas, it is difficult to remove from fences, porches, and buildings and can incur costs for property owners.
Leaves of porcelain berry vary in shape from a simple heart-shaped leaf with coarse teeth, to a deeply loped leaf with rigid edges. Flowers are green to white and form in small clusters in mid-summer. Fruit are small berries that can range in color from yellow to purple to blue and have a shine to them similar to porcelain–hence the name.
Distinguishing Invasive Porcelain Berry
From native Species of Grape
Differences can be seen in the bark of these species as the native grape bark is a reddish color and has a shredded appearance,
whereas porcelain berry bark is brown to gray in color and has a rigid and furrowed appearance.
Another difference is the pith of native grape is brown while invasive porcelain berry has a white pith.
A combination of mechanical and chemical methods is most effective. Large vines must be cut near the ground and treated with a chemical herbicide or repeated cutting must occur. Garlon 3A, Garlon 4, as well as Roundup and Rodeo, have been used successfully. All courses of treatment should be completed before fruiting occurs to avoid building a seed bank.
