Euphorbia milii, the crown of thorns, Christ plant, or Christ thorn, is a species of flowering plant in the spurge family Euphorbiaciae, native to Madagascar. The species name commemorates Baron Milius, once Governor of Réunion, who introduced the species to France in 1821. It is imagined that the species was introduced to the Middle East in ancient times, and legend associates it with the crown of thornsworn by Christ.
When grown outdoors, the Euphorbia Milii needs a lot of sunlight and well-draining soil. In extremely hot and dry climates, the plants will need shade as the hot midday sun can burn the leaves.
- Crown of Thorns succulents are versatile and adaptable houseplants. All they need is a well-drained container that’s just an inch or two larger than the root system. When planted in too much soil, the plants can be susceptible to root rot, especially if the soil is damp for extended periods.
