About Helianthemum asperum
Helianthemum asperum, commonly known as Ashy Sun Rose, is a small perennial shrub belonging to the Cistaceae family, native to the Mediterranean region. It is characterized by its small, grayish, rough leaves covered with hairs that give it a whitish or 'ashy' appearance, and by its delicate yellow flowers that emerge in spring and early summer. It is ideal for rock gardens, low-maintenance gardens, and sunny borders, adding a wild and bright touch.
Native range
Iberian Peninsula and North Africa
Care tips
This sun rose thrives in full sun and well-drained soils, even poor or calcareous ones, being very drought-tolerant once established. Water moderately only during prolonged dry periods in its first year; thereafter, it is practically self-sufficient. Avoid excessive moisture in the substrate, as it is prone to root rot. A common mistake is attempting to grow it in partial shade or heavy, damp soils, which will severely compromise its flowering and overall health.
