Cushion Spurge (Euphorbia Polychroma) - This flower seed is one of the more popular Euphorbia perennials. The leaves turn from yellow to bright green to red as the seasons change from Spring to Summer to Fall. Cushion Spurge gets it name because it grows in a rounded mound that resembles a cushion. Cushion Spurge performs beautifully as an edging along a formal walk or winding garden path, as a rock garden or border specimen, planted atop retaining walls, or massed in moderate expanses as a facing or general cover. In the northern zones the plant will do fine in full sun, but in southern zones the plant will need some afternoon shade to thrive. It is very drought tolerant. Foot traffic is not well tolerated.
After flowering, the plant should be cut back by about a third, which will keep the plant compact and keep them from falling apart at the center. It will self seed easily, so cutting the plant back will slow this process down. Wear gloves when handling the plant since the white sap is a skin irritant. Avoid too much fertilizing as plant will become leggy.
