African Milk tree

Euphorbia trigona, commonly called African milk tree, is an upright, shrubby, branching succulent native to central Africa where it typically grows in seasonally dry tropical forests. It is widely cultivated in warm, tropical, subtropical, and arid regions an ornamental plant, and around the world as a houseplant. This species has escaped cultivation in India where it grows in disturbed areas and roadsides, forming thickets and spreading mostly vegetatively though fallen stem fragments. Mature plants can reach up 6-12' tall with a stout, cylindrical, grey trunk and fleshy, 3-5 sided branches. Small, sharp spines and ovate leaves are held along the sides and tops of the stems. The leaves are dropped seasonally. Small, inconspicuous flowers are produced seasonally by mature specimens, but they are not considered horticulturally significant and plants in cultivation rarely flower.
