Euphorbia

Want a succulent that thrives in neglectful conditions; one that only requires sun to partial shade and little water? Do you crave a plant with an eye-catching lime green color that makes it difficult for the observer to look at anything else? Then consider the Euphorbia (sounds like you-forb-bee-ah), 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 intertwined into a circle. It has been substantiated 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 having evolved from the Chinese words of “poy” which means 8, and “sean” which means saint. It is believed that when the plant produces 8 flowers in an inflorescence, luck will follow.

A member of the Spurge family, it is related to poinsettia. While this plant has an extremely long bloom season, the large green bracts (or leaves) beneath the blooms provide just as much beauty. Growing to a height of 18 inches and hardy from USDA zone 9 to 10, they are a spectacular addition to any xeriscape garden.

Consider also the Euphorbia wallichii, which is a clump-forming perennial with erect stems, linear leaves, and bright yellow flowers that grace early summer days. Growing to a height of 2 feet, it is hardy from zone 6a to 9b. An extremely versatile plant, this fast-grower would hold its own in a garden scheme based on hot, vibrant colors. Try contrasting the white-veined, dark green leaves against bronze or purple foliage plants. We suggest the lobelia or Polygonium capitatum (knotweed). The euphorbia is perfect for beds, borders, containers, cottage gardens, and Mediterranean gardens.

With many species available, including the Euphorbia into your garden can prove to be a delightful and pleasing experience.
