Distribution and Habitat

Originally from southeastern Europe and Asia, Lycium barbarum has been introduced to other continents, including North America and Australia, where it is grown both as an ornamental plant and for its berries. It thrives in well-drained, alkaline soils and requires full sun for optimal growth and fruit production.

Cultivation

Cultivation of Lycium barbarum requires careful management of watering and sunlight exposure. The plants are drought-tolerant but produce higher yields with regular irrigation. They are also relatively resistant to pests and diseases, making them suitable for organic farming practices. Pruning is essential to maintain plant health and maximize berry production.
