Identifying and Propagating Euphorbia milii (Crown of Thorns)

A blooming plant with soft leaves, woody spiny stems, and constant flowers is Euphorbia milii (crown of thorns), a succulent—not a cactus. Propagate the cutting in 1:1 sterilized soil and coarse sand/perlite, slightly moist. Plant deep enough to stand in a small pot. Water ~1 tsp/week. Rooting is slow but reliable. Wear gloves—milky sap irritates skin. Patience is essential.
