Around 1860, oriental bittersweet entered cultivation as an ornamental vine; by 1974, it had spread to 33 states and was smothering native plants
Introduced from Asia around 1860, Oriental bittersweet was initially prized for its bright berries and vigorous growth. This attractive vine soon became a popular ornamental plant in gardens and nurseries across North America. However, its aggressive nature led to it becoming a destructive invasive species, strangling native trees and plants. Birds and nursery sales facilitated its rapid spread across many eastern United States states.
