Oriental bittersweet (Chinese bittersweet, Asian bittersweet, Round-leaved bitte)

The defining characteristic of the plant is its vines: they are thin, spindly, and have silver to reddish brown bark. They are generally between 1 and 4 cm (0.4 and 1.6 in) in diameter. When Celastrus orbiculatus grows by itself, it forms thickets; when it is near a tree or shrub, the vines twist themselves around the trunk. The encircling vines have been known to strangle the host tree to death, which is also true of the American species, C. scandens. The leaves are round and glossy, 2–12 cm (0.8–4.7 in) long, have toothed margins and grow in alternate patterns along the vines. Small green flowers produce distinctive red seeds which are encased in yellow pods that break open during autumn. All parts of the plant are poisonous.
