Plant Profile: Lycium

Box thorns are shrubs that can be either deciduous or evergreen, belonging to the nightshade family, with approximately 70 to 80 different species. These plants primarily thrive in arid and semi-arid regions, although some can also be found in coastal areas with saline conditions. Characteristically, they possess thorny stems and produce small flowers, which give way to berries that can be red, purple, or yellow.

Among the more recognized varieties are Goji berries and Wolfberries, both of which are valued for their health benefits and medicinal uses. Goji berries tend to spread along the ground, making them easier to harvest when supported by stakes.

In Australia and New Zealand, certain species have become invasive, creating dense thickets that pose a threat to livestock and outcompete native vegetation.
