African Milk Tree Cactus

African milk tree is a tall, branching succulent with three-sided green stems, paired spines along the ridges, and small teardrop-shaped leaves. Its upright, candelabra-like form can reach 6–12 feet tall and 5–10 feet wide. [NC State Extension](https://plants.ces.ncsu.edu/plants/euphorbia-trigona/common-name/african-milk-tree/) notes that flowering is rare in cultivation, though small green or yellow flowers may appear in spring and summer in its native habitat. ## Siting and Water Use it as a bold container specimen indoors, or outdoors in a warm climate where frost is not a concern. Provide bright light, a well-drained sandy or loamy mix, and water sparingly once the surface soil has dried. A movable container makes it easier to shelter the plant from cold. Overwatering can cause root rot; inspect periodically for mealybugs, aphids, or spider mites. ## Maintenance Handle carefully: the milky sap can irritate or blister skin, and the plant should be kept away from pets and children. Wear gloves when pruning or taking cuttings. In warm regions it can be used in a rock garden or hedge, but it has naturalized in some tropical areas, so avoid discarding cuttings outdoors.
