The Euphorbia x martinii "Ascot Rainbow" is a perennial succulent. Heat and drought tolerant, it is an ideal addition to your Mediterranean-style garden. The attractive variegated, cream, lime, green and pink flowers compliment its yellow-edged leaves each spring. The plants are not large, growing to 20 inches tall by 20 inches in diameter. Ascot Rainbow needs very little pruning, but take care when you pinch back or deadhead the old flower stalks.
