Easily grown in average, dry to medium, well-drained soils in sun or shade. Foliage will often scorch in hot, dry, full sun conditions. Tolerant of a wide range of soils. Flower heads may be removed to prevent self-seeding and to maintain appearance of the ground cover. Any unvariegated shoots which appear should also be removed as they tend to be more vigorous and can quickly take over a planting. If foliage declines in summer, plantings may be sheared by mowing on a high setting to remove the unsightly leaves and to stimulate new foliage growth. Spreads by underground stems (rhizomes) and can be quite aggressive. If not grown in self-contained areas, mechanical barriers may need to be installed to prevent unwanted spread of plants.
