Celastrus orbiculatus is a woody vine of the family Celastraceae.[1] It is commonly called Oriental bittersweet,[2][3][4] as well as Chinese bittersweet,[3]Asian bittersweet,[4]round-leaved bittersweet,[4] and Asiatic bittersweet.
It is native to China, where it is the most widely distributed Celastrus species, and to Japan and Korea.[5] It was introduced into North America in 1879,[6] and is considered to be an invasive species in eastern North America.[7] It closely resembles the native North American species, Celastrus scandens, with which it will readily hybridize.[8]
