Celastrus orbiculatus
Common Name(s):
- Phonetic Spelling
- sel-ASS-trus or-bik-yoo-LAY-tus
- This plant is an invasive species in North Carolina
- Description
-
Plants are either male or female
Native to Eastern Asia; listed as an invasive species by the NC State Weed Specialist, North Carolina Forest Service, USDA National Invasive Species Information Center; the Invasive Plant Atlas of the United States, The National Park Service
Found primarily along forest edges, roadsides, and meadows in full sun. Spreads by prolific vine growth and seeds that are spread by birds, mammals, and people. It was introduced from Southeast Asia around 1860 as an ornamental vine.
Bittersweet can be difficult to control. Cutting or pulling alone does not work because cutting stimulates the vine to re-sprout ten-fold and any broken-off piece of root will re-grow. In the home landscape, it is probably best to cut the vines back to the ground and immediately treat the cut stem with herbicide. Follow the directions on the label.
