The species, Euphorbia characias is native to Southern Europe, Turkey. The name for the genus is derived from Euphorbus, the Greek physician of King Juba II of Numidia and later of Mauritania. In 12 B.C. King Juba named a cactus-like plant he found in the Atlas Mountains after his physician and later Carl Linnaeus assigned the name Euphorbia to the entire genus. The specific epithet was the Greek name used by Dioscorides for the plant, which was long used medically for the compounds it contains.
