Euphorbia unispina, commonly known as Single-Spined Euphorbia or Somali Spurge, is an evergreen succulent plant native to west tropical Africa. It is typically found in xeric environments, such as rocky outcrops and slopes, where it has adapted to survive with minimal water. This succulent can reach a height of 3-5 feet (0.9-1.5 meters) and a width of 2-3 feet (0.6-0.9 meters), and it features a distinctive, candelabra-like growth form with spiny stems. The flowers are small, yellow, and inconspicuous, blooming in the spring. They are not the main attraction of this plant; rather, its architectural form and spines provide visual interest.

Single-Spined Euphorbia is valued for its sculptural appearance, making it a suitable choice for rock gardens and as a focal point in landscapes. It thrives in full sun or part shade, preferring fast or medium-draining sandy or loamy soils. While it requires little maintenance, it is important to avoid overwatering to prevent root rot. Gardeners should handle this plant with care, as the sap is toxic and can cause skin irritation. There are no major disease issues, but it can be susceptible to pests like mealybugs and spider mites. Due to its spines and toxic sap, it is not recommended for gardens with small children or pets.CC BY-SA 4.0
