Christplant, scientifically known as Euphorbia milii, is a woody succulent shrub that brings dramatic flair to warm-climate gardens with its showy red or yellow bracts and formidable thorns. Native to Madagascar, this tough plant thrives in USDA zones 10-12, reaching 3 to 6 feet tall depending on growing conditions, and rewards minimal care with reliable blooms. Its ability to tolerate poor, rocky soils and dry conditions makes it a standout choice for gardeners dealing with challenging terrain or water restrictions.

The crown of thorns earned its name from the striking appearance of thick, sharp black thorns covering its fleshy stems alongside inconspicuous flowers wrapped in showy, petal-like bracts in vivid red or yellow. This is a plant that demands attention: drought-tolerant yet responsive to moderate moisture, it thrives in full sun across zones 10-12 and laughs at poor, rocky soils that defeat less hardy species. Deer and rabbits leave it untouched, and it handles urban conditions with ease, making it surprisingly low-maintenance for a plant this visually commanding.
Christplant functions as an ornamental focal point in warm-climate landscapes, container gardens, and as a houseplant in cooler regions where it can be brought indoors during winter. Its dramatic thorny stems and showy bracts make it a striking accent plant for xeriscaping and low-water garden designs.
