An attractive, vining shrub, Goji features light purple, bell-shaped flowers and abundant, bright red berries that ripen from mid-summer to late fall. In China, Goji’s pleasantly sweet and flavorful fruit is eaten fresh and used in many dishes. A valuable medicinal plant, Goji berries are very high in anti-oxidants, have more carotene than carrots, and contain all essential amino acids and many minerals. Goji is hardy to minus 15°F. or below and is self-fertile.
