Euphorbia milii (formerly Euphorbia splendens) - Crown of Thorns
Crown of Thorns is a slow growing semi-succulent shrub that blooms showy bracts in a variety of colors. Branches and stems are covered in 1/2 inch thorns. It likes sandy, well-drained soil and is drought tolerant, but looks best with regular light watering. Great for use in containers, rock gardens or as a low barrier. Care should be taken when handling as sap can irritate skin. Plant in full sun or partial shade.
