Lycium chinense — Chinese matrimony-vine

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Chinese matrimony-vine has long been cultivated in China for its red fruits (Goji berries), which have many medicinal properties and make a refreshing tea. Birds love the berries, too. This small, arching shrub has a few thorns on its branches, which produce lavender flowers in May to August. Lycium chinense is closely related to the other member of its genus in New England (which also produces edible berries): L. barbarum. Lycium chinense has a calyx that is more deeply lobed, deeply lobed petals with hairs near their edges, and wider leaves than L. barbarum.
