The crown of thorns cactus (Euphorbia milii) is an evergreen, succulent plant, native to Madagascar, however it has been successfully acclimatized and grown commercially in many parts of the world.
Very hearty, require little maintenance, easy to grow. Drought tolerant. Allow soil to dry out.
Indoors or out until nights dip below 45 degrees. Appreciated for its showy flowers and lush, thick, gray-green leaves, the crown of thorns is a good choice for outdoor beds or mixed borders in U.S. Department of Agriculture hardiness zones 10 through 15. In cooler regions subject to frost, it does well as a houseplant in a sunny window and can successfully overwinter indoors.
If leaves fall off either too much or too little water. Do not let water stand on roots, causes rotting. Too much sun causes leaves to fall off, thus introduce to outside sun gradually if moving from indoors to out. Prefers to stay in one location once established. Likes full sun during part of the day.
There exists substantial evidence that the species, native to Madagascar, had been brought to the Middle East before the time of Christ.
