Growing Conditions

Prefers full sun and well-drained, even poor or sandy soil. Excellent drought tolerance once established. Hardy in USDA zones 3–8. Avoid heavy, wet soils, especially in winter, to prevent root rot.

Landscape Uses

Excellent for rock gardens, alpine troughs, edging, and between stepping stones. The aromatic foliage is deer and rabbit resistant. Flowers are suitable for fresh or dried arrangements.

Maintenance

Deadhead spent flowers to prolong bloom and prevent self-seeding. Divide clumps every 2–3 years in spring or fall to maintain compactness. Cut back foliage in late fall or early spring.
