Euphorbia horrida

It is a shrub succulent plant that tends to cluster at the base over time. Its bluish-green stem if of a grayish-white shade, has a waxy texture, which loses as it ages. Its multiple irregular ribs can take on a wavy shape and are framed by stiff brownish spines. Flowering occurs in summer, covering the apex of the plant with small flowers of variable colors, ranging from yellow to deep purple.
