Oriental or Asiatic Bittersweet (Celastrus orbiculatus) is a highly invasive, non-native vine that grows vigorously, damaging trees and other plants and forming dense stands. Bittersweet produces an abundance of bright fruits, which are spread by birds and other animals to new locations.
The sale of Oriental bittersweet has been prohibited in Connecticut since 2004. The law also prohibits the importation, purchase, and cultivation of bittersweet and other listed plants. Fines for violations of the law are listed at $50 per plant. The law includes all reproductive portions of the plant, including seeds.
