About Euphorbia canariensis L.
Euphorbia canariensis L., commonly known as Canary Island spurge, is a succulent shrub that grows 3 to 4 metres (10 to 13 feet) high. It forms from fleshy four- or five-sided trunks that have a cactus-like appearance. It does not produce leaves, and instead bears spines that measure 5 to 14 millimetres (0.20 to 0.55 inches) long. It grows reddish-green flowers, and can tolerate temperatures as low as −2 °C (28 °F). Its poisonous latex contains diterpenes. This species grows in the narrow coastal belt of the Canary Islands, at elevations ranging from sea level up to 1,100 metres (3,600 ft).
