Porcelain berry leaves and fruits

Porcelain berry (Ampelopsis brevipedunculata)

Deciduous perennial vine; stems have lenticels; white pith; may grow up to 15’ in one season.

Overview

Regulated areas of Porcelain berry
Porcelain berry is Prohibited (Red counties)

Other names for this plant include:

  • Common names: Amur peppervine, porcelain vine, varigated porcelain berry
  • Scientific names: A. glandulosa var. brevipedunculata; A. brevipedunculata var maximowiczii

Ecological threat:

  • Shades out native vegetation by forming a dense blanket.
  • Also climbs up trees and shrubs increasing the possibility for downing during storms.
  • Prefers moist woods, floodplains, stream banks, and woodland edges.

Classification in Wisconsin: Prohibited

Species Assessment Groups (SAG) were assembled to recommend a legal classification for each species considered for NR 40. The recommendation for porcelain berry was based upon this literature review developed by the department.

Identification

Leaves: Climbing tendrils opposite of dark green leaves – shapes vary from heart to palmately lobed – dissected. Hairs present on the leaf veins.

Flowers: Small green-white flowers bloom in clusters during mid-summer.

Fruits & seeds: Shiny, clustered berries occur in fall and are a range of colors from pink to purple to blue with small white and gray spots; flesh is white.

Roots: Fibrous; can resprout from root fragmentation.

Similar species: Native grapes (Vitis spp.) are also woody vines but with shredding bark when mature. Leaves are sometimes hairy, but generally on the surface of the leaf and sometimes on the veins. Stem pith is brown compared to porcelain berry’s white pith and the fruit of native grapes are green, black, or purple and watery.

Chemical: Cut stump with glyphosate; basal bark in fall with triclopyr and surfactant.
