About White rock-rose
Helianthemum apenninum, commonly known as 'White Rock-rose', is a perennial, prostrate subshrub that forms dense mats, perfect for rockeries and Mediterranean gardens. Its delicate white flowers, often with a yellow center, beautifully contrast with its grey-green foliage. It's an excellent choice for ground cover in sunny, dry areas, adding a wild yet elegant touch.
Native range
Mediterranean region (Southern Europe, North Africa, and the Middle East)
Care tips
It requires full sun for abundant flowering and optimal development, tolerating high temperatures well. This plant is very drought-tolerant once established, so watering should be sparse, especially in winter to prevent rot. It prefers well-drained, poor to moderately fertile soils, and preferably alkaline or neutral. Avoid overwatering and heavy, clayey soils, which can be fatal for this species.
