Canary Island Spurge is a small tree, growing to 3 metres (9.8 ft) to 4 metres (13 ft) high. Fleshy quadrangular or pentagonal trunks that are like a cactus. The leaves grow in clusters of three or four and have 'turned into spines' 5 millimetres (0.20 in) to 14 millimetres (0.55 in) long. Reddish-green flowers.[5] Hardy to −2 °C (30 °F).[6]
The latex which contains diterpenes[7] is considered highly toxic.[8]
