Celastrus orbiculatus, commonly known as the Oriental bittersweet, is a woody vine native to East Asia. Although its invasive nature has caused concern in North America, where it has been introduced, it is well regarded for its ornamental features. The plant's leaves are dark green, and its flowers appear in the summer, followed by berries that turn yellow as they mature. In addition to Oriental bittersweet, the vine is also known as Chinese bittersweet, round-leaved bittersweet, and climbing spindleberry. These synonyms are often used interchangeably depending on the region and context in which they are mentioned.
