Lycium exsertum, commonly known as Arizona Desert-Thorn, is a deciduous shrub native to the Sonoran and Mojave Deserts in the Southwestern United States and Northwestern Mexico. This plant typically grows to a height and width of 4-8 feet (1.2-2.4 meters), featuring a dense, spiny branching habit that provides cover for wildlife. The Arizona Desert-Thorn is well adapted to its arid environment, thriving on well-drained sandy or gravelly soils. It produces small, tubular purple flowers that are quite showy during the winter and spring months, followed by red berries that attract birds and other fauna.

Arizona Desert-Thorn is valued for its drought tolerance and ability to thrive in harsh desert conditions, making it an excellent choice for xeriscaping and naturalistic plantings in arid regions. It is also used for erosion control and as a habitat plant for wildlife. In cultivation, it requires minimal maintenance once established, needing only occasional pruning to maintain shape and remove dead wood. It prefers full sun exposure and tolerates a range of soil types, provided they offer good drainage. While generally pest-free, it can occasionally suffer from root rot if overwatered or planted in poorly draining soils.CC BY-SA 4.0
