African Milk Tree Care Guide

About African Milk Tree

Meet the African milk tree (Euphorbia trigona), a bold, architectural succulent known for its upright form and striking, ridged stems. The Euphorbia African milk tree is a tropical plant that showcases triangular green stems, small leaves, and thorns.

This unique succulent (not a true cactus) originates from Central and West Africa and thrives in USDA hardiness zones 9–11. It can reach impressive heights indoors with the right light and care.

Keep in mind that, like many euphorbia plants, its milky sap can be irritating to pets, so it is best placed out of reach. Symbolically, this houseplant is often associated with resilience and growth due to its upright, enduring structure.
