A hardy perennial, often forming dense colonies once established. A native of Europe, it has naturalized throughout all regions of the United States. The leaves are very thick, and feel leathery to the touch.
Flowers are pure white with mustard-yellow centers, individually borne on single erect stems.
Prefers fertile soil, in full sun or partial shade. Competes well with grasses. Excellent as a ground cover or border since the foliage is attractive and remains green year round. An ideal cut flower for arrangements lasting up to ten days. A prolific reseeder.
