Invasive Plant Factsheet
Originally from eastern Asia, this vine was introduced in 1845 as an ornamental plant. It has now been found to be infesting forest habitats where it can grow from 20 to 40 feet in a season, smothering native understory plants. It is considered problematic in several Mid-Atlantic states, including Virginia, where both Arlington and Alexandria list it as invasive.
