Growing Sun Rose (Helianthemum): Drought-Tolerant Rock Garden Gem

Growing Helianthemum (Sun Rose)

Pronunciation: hee-lee-an'-them-um

Sun roses form low, shrubby mats smothered in single, rose-like flowers in spring. They demand full sun (part shade in South), lean, well-drained soil, and little to no fertilizer.

Care

Shear back by ⅓–½ after flowering to keep tidy. Do not cut back in fall. Remove winter-damaged stems in spring. Hardy to zone 6; in zone 5, cover with hay or evergreen boughs in December, remove when daffodils bloom.
