Variegated Devil's Backbone (Euphorbia tithymaloides 'Variegatus'): Zigzag Stems with Cream Edges

Variegated devil's backbone (Euphorbia tithymaloides 'Variegatus'), also called Japanese poinsettia, slipper spurge, or redbird cactus, is a succulent shrub with distinctive zigzag stems and fleshy, oval leaves edged in creamy white. The stems bend at each leaf node, creating a architectural, staircase effect.

Features

Grows 2–4 feet tall. Small, red, slipper-shaped flowers (cyathia) appear at stem tips in winter. The milky sap is irritating. The variegation is most pronounced in bright light.

Culture

Bright, indirect light; well-draining cactus/succulent soil. Water when dry. Protect from frost (zones 10–11). Wear gloves when handling. Excellent architectural container plant.
