Summary

Origin and growth: native to tropical Asia, including India and Sri Lanka, this spurge is an upright shrub or small tree with ridged three- to four-sided stems and spines; it reaches outdoor heights of about 3–6 m (indoor forms are smaller) and features green branches with pale center and marbled whitish/lime-green markings, tiny deciduous leaves, and a milky latex sap that is phototoxic in sunlight and toxic if ingested.

Cultivation and uses: to thrive, provide bright sun to partial shade and well-draining soil. It is drought-tolerant and warm-climate tolerant, with water applied when the topsoil dries. It is suited to frost-free climates (USDA zones 10a–11b). Fertilize with diluted 10-10-10 during growth. Propagate by stem cuttings; crested or variegated forms are often grafted onto rootstock. Wear gloves when handling due to toxic sap. Commonly used as an ornamental hedge or focal plant in landscapes, indoors or outdoors depending on climate.
