Plant Profile: Ampelopsis brevipedunculata

**Ampelopsis glandulosa var. brevipedunculata**

Porcelain-berry, a highly invasive weed found in the eastern United States, bears a striking resemblance to native grape species. It is classified as an Invasive, Exotic Plant in the Southeast due to its ability to reseed prolifically, leading to the establishment of invasive seedlings.

This plant tends to invade streambanks, pond edges, forest peripheries, and other disturbed environments. The dense mats created by this climbing vine can overshadow and outcompete native shrubs and young trees. Its rapid spread is facilitated by birds and mammals that consume its fruit and subsequently disperse the seeds. Originally from Japan and northern China, Porcelain-berry was introduced to the United States in 1870 for ornamental and landscaping purposes.

Characterized as a deciduous, woody climbing vine with minimal tendrils, it can grow over 20 feet (6.1 meters) tall or take on a trailing or erect shrub form. This species thrives in moist, well-drained, nutrient-rich soils and can adapt to various light conditions.

The plant produces flowers on new growth, and to manage its spread, it is advisable to cut it back to the ground in late winter.

Porcelain-berry can be found in forests and other natural habitats, but it often becomes weedy in disturbed landscapes. It is also cultivated as an ornamental vine, commonly seen climbing fences, walls, and trellises.

**Insects, Diseases, and Other Plant Issues:** The foliage is susceptible to damage from Japanese beetles.
