In cooler zones, Spurge grows well in full sun. In warmer regions, it is best sited in part shade, avoiding afternoon sun. It prefers average, well-drained soil. 'Ascot Rainbow' typically does not need to be cut back after flowering. At the end of the season, it typically remains standing through the fall into early winter. It is one of the last perennials to go dormant. Cut it back in early spring before new shoots emerge for a better flowering performance.
