African Milk Tree Cactus: Euphorbia trigona – 14 inch pot – 4.5-5.5 foot tall

Despite its name, the African Milk Tree Cactus (Euphorbia trigona) is not actually a cactus. Instead, this big thorny plant is a succulent. The African Milk Tree grows thick three-sided stalks with the typical cactus-style arms, and features small, short-lived leaves. This Euphorbia is popular for its distinct structural shape and minimal care requirements.
