Goji berry is one of natureâs most nutrient-rich foods. This âsuperfruitâ is packed with vitamins, minerals and antioxidants to boost immunity and longevity. A deciduous perennial plant, it grows from 3-9â in height. Purple flowers appear in late spring to early summer and the bright orange-red Goji berries ripen from August to October. The sweet tasty fruit is harvested by shaking the vine. Once the berries, about the size of raisins, are fully ripe and full of nutrients, they fall off the vine easily. The berries may be eaten fresh or sun-dried to be enjoyed later. Plant in full sun and well-drained soil. Our âCrimson Starâ Goji Berry plant usually fruits the first year.
