A member of the grape family, porcelain berry (Ampelopsis brevipedunculata) is a fast-growing, deciduous, woody vine. It climbs via tendrils and vines can grow up to 20 feet long. In Minnesota, it is listed as a Restricted Noxious Weed meaning it cannot be sold, propagated, transported, or planted legally in the state.
Native to Asia, porcelain berry was introduced to the U.S. as a landscape plant in the 1870s. It is widespread throughout the East Coast, is a particular problem in the southeastern United States, and is slowly spreading westward.
Porcelain berry has been found in Iowa, Wisconsin, and Minnesota where it has been found naturalizing in Rice and Ramsey counties.
Porcelain berry is the Minnesota Department of Agriculture's August weed of the month. You can read more about it on the MDA website.
