Cushion Spurge (Euphorbia polychroma): Electric Yellow Spring Bracts & Fall Color

Cushion spurge (Euphorbia polychroma) blooms with electric yellow bracts on a low cushion in April, persisting as stems elongate to form a 16-inch mound by midsummer. Leaves produce shades of red, orange, and purple in autumn.

Culture & Propagation

Grow in full sun to partial shade in moist but well-drained soil. Self-sows regularly. Sap irritates skin and causes severe discomfort if ingested. Sow seeds when ripe or in spring; divide in early spring.

Potential Problems

Nematodes, spider mites, aphids, mealybugs, fungal and bacterial diseases.
