Euphorbia resinifera grows on the slopes of the Atlas mountains in Morocco.
The stems contain a milky latex which is very irritant to the eyes and other mucous membranes. A high concentration of resiniferatoxin occurs in this sap which is presently being tested for analgesic properties. (http://en.wikipedia.org/wiki/Resiniferatoxin )
In warm climates Euphorbia resinifera is a robust grower and large clumps are formed after a few years in cultivation.
The propagtion is from seed or cuttings.
