Scientific profile
Helianthemum nummularium is an evergreen, broad-leaved subshrub that typically forms a low mat and reaches about 12 cm in height. The stems do not become woody, and the leaves persist throughout the year. Flowering takes place from May to July. The species is native in Great Britain, where it is found on dry, sunny, calcareous and nutrient-poor soils, often in open grassland and rocky sites. It requires full sun and alkaline conditions, and forms arbuscular mycorrhizal associations in the soil.
