Goji berries, or wolfberries, are a recently popular superfruit grown commercially mainly in China, but which can be grown elsewhere as well. Goji berries come from a woody perennial plant in the nightshade family (Solanaceae), and the small red to orange berries are said to be powerhouses of vitamin C, beta-carotene, and other nutrients, including 18 amino acids.
There are two main varieties of Goji berry plants, Lycium chinense (a shorter variety from the south of China), and Lycium barbarum (from the north of China, and tending to be taller), both of which yield a similar fruit. It may take up to three years of growth after planting to get fruit on the plants, although earlier small yields are possible. Goji can also be grown as a container plant, but will remain smaller and have smaller yields.
