Origin and Habitat: Euphorbia waringiaeSN|21534]]SN|21534]] is endemic to the Esomony area, south-east Madagascar. Its exact distribution range is unknown but is likely to be very restricted, as only one population is known.
Habitat: Tropical subarid shrubland, at the bottom of the mountains at east of Esomony, in a well drained soil. It is located under shrubs, in thicket in stony red earth and on coastal Dunes. Major Threats are habitat degradation, fire, habitat clearing, collection for horticultural trade.

Cultivation and Propagation: It is a slow-growing and cold-sensitive species, it can to grow in both pots and in the ground, in areas with a mild climate, but they can even be grown indoors. They grow well in a very draining mineral potting substrate. During the summer, they enjoy average feeding and watering. When dormant, plants are relatively cold-tolerant.
Sun Exposure: Light shade.
Propagation: Usually by seeds, it can also It be propagated by cuttings; if you remove an offset, remember to let it dry for a week or so, letting the wound heal (cuttings planted too soon easily rot before they can grow roots). It is better to wash the cut to remove the latex.
Warning: As with all other Euphorbias, when a plant gets damaged it exudes a thick white milky sap known as latex. This latex is poisonous and may irritate skin, so pay extreme attention not to get any in your eyes or mouth.
Cultivated plants must be handled carefully.
