Want a succulent that thrives in neglectful conditions; one that only requires only sun to partial shade and little water? Consider the Euphorbia milii, which is also known by the names “Crown of Thorns,” “Christ Plant,” and the “Siamese Lucky Plant.” The two former names allude to the legend that the crown of thorns worn by Christ at the time of his crucifixion was made from stems of this plant, which are pliable and could be woven into a circlet. It has been confirmed that the species, which is native to Madagascar, had been brought to the Middle East prior to the time of Christ. The name of “Siamese Lucky plant” references the Thai name “Poysean,” which evolved from the Chinese words of “poy” which means 8, and “sean” which means saint. It is believed that when the plant produces eight flowers in an inflorescence, luck will follow.
A member of the Spurge family, it is related to poinsettia. And like the poinsettia, the sap can cause skin irritation and is mildly poisonous if ingested. Growing to a height of 18 inches, it is a spectacular addition to any xeriscape garden. As with any succulent, do not overwater!
