Euphorbia plants range from small annual plants to large trees. In fact, it’s the largest genera of flowering plants with over 2,000+ members. The genus Euphorbia is pronounced u-FOR-bee-ah. And, this immense genus is not limited to succulents. Some euphorbias are commercially widely available. For example, the poinsettia at Christmas. Additionally, some are commonly cultivated as ornamentals. Or, collected for their unique structures. 

Succulent euphorbias may resemble cacti, but are native to Africa. Unlike cacti who are native to Southwest deserts and Mexico. Spines of cacti radiate from a central point (aureole), which euphorbias lack. Cactus flowers tend to be large and brilliantly hued. Alternatively, euphorbias are pea-like spheres that open to tiny white or yellow blooms. Furthermore, they are quite small relative to the plant. 

Take care as the milky latex-like sap of euphorbias is caustic and extremely irritating to the eyes. Should you get it on your skin, wash thoroughly with soap and water. Keep away from children and pets. Many euphorbias resemble undersea creatures or coral. Among the look-alikes included here are Euphorbia tirucalli
‘Firesticks’, Lactea, and Medusa’s Head.
