Masai spurge is a colorful, perennial, succulent plant with miniature, orchid-shaped, bright red blooms with yellow centers that form 1½-inch dense, multi-flowered clusters. The ¼-inch yellow-green stems arise from tuberous roots and grow to 2 feet tall, bearing thick, green leaves. Native to Tanzania and hardy in USDA Zones 9b-10b, the easy-to-grow Euphorbia neococcinea thrives in bright light and well-drained soil. Outdoors during Chicago summers, it is drought tolerant and resistant to deer. It also does well indoors in a sunny location. However, the seeds and all other parts of the plant are poisonous if eaten. Handling the plant may also cause skin irritation or an allergic reaction because all members of the Euphorbia genus produce a milky sap called latex that ranges from being a mild irritant to being very poisonous.
