Celastrus orbiculatus, also known as Oriental Bittersweet, is a woody vine indigenous to East Asia, specifically China, Japan, and Korea. Since its introduction in America in 1879, it has become an invasive species in eastern North America. Its seeds can be easily dispersed by animals and it can easily outcompete native species for available resources. Oriental Bittersweet vines have silver and reddish-brown bark and glossy, round leaves. Small green flowers yield distinctive red seeds enclosed in yellow pods that open in autumn. While different parts of the plant have traditional medicinal uses such as antiphlogistic, antirheumatic, depurative and tonic properties, all parts of the plant are poisonous. The plant enjoys moderate rainfall environments and strong responses to sunlight are fundamental to its success as an invasive species. Oriental Bittersweet can grow in a variety of environments and forms mutualistic associations with mycorrhizal fungi that enable it to more effectively uptake required nutrients. Given the species' invasive tendencies, it should only be grown in areas proven not to be invasive.
