About

Euphorbia abyssinica, commonly known as the desert candle or candelabra spurge, is a species of plant in the family Euphorbiaceae. E. abyssinica is endemic to Ethiopia, Somalia, Sudan and Eritrea. It was first described in 1791, by the German botanist Johann Friedrich Gmelin. In its native habitat, it can grow up to 10 m (33 ft) tall. The woody stem is used for firewood and as timber in roofing, furniture and other items, and the sap is used in traditional medicine. It is also cultivated as an ornamental house plant.

Where it grows

E. abyssinica is native to the Horn of Africa where it grows in Ethiopia, Somalia, Sudan and Eritrea. It is found on arid hillsides, in montane woodland and on scrubby savannahs, sometimes in dense groves and other times growing by itself. It occurs at altitudes of 840–1,460 m (2,760–4,790 ft).

Uses

Euphorbia abyssinica is cultivated as an ornamental house plant, being promoted for its architectural form and ease of maintenance. It is also grown as a garden plant in suitable climates, including under its synonym Euphorbia acrurensis. In its native countries, the woody tree-like stem is used for firewood and as timber in roofing, furniture, wooden saddles and other items. The sap can be used to kill ticks on cattle. In traditional medicine, the sap has been mixed with butter to treat fungal infections of the skin. The sap has also been used in cases of visceral leishmaniasis and malaria. It has also been found to promote the rooting of cuttings of such plants as Boswellia papyrifera. This is because the sap contains the growth regulator hormone indole-3-acetic acid; branches and twigs that become detached root easily, and the plant is sometimes used to form a living fence. When propagated by cuttings, E. abyssinica does not develop the distinctive trunk different in appearance from the branches that is characteristic of naturally occurring plants.
