Common Houseleek

<em>Sempervivum tectorum</em>, commonly known as the common houseleek or hen and chicks, is a succulent perennial in the family Crassulaceae. It is classified as Least Concern on the IUCN Red List, with a broad distribution spanning Asia (including Taiwan), 17 European countries, and North America. The species typically grows on rocky outcrops, old walls, rooftops, and dry, well-drained soils in temperate and montane environments. Adapted to harsh, nutrient-poor conditions, it has been cultivated for centuries as both an ornamental and a plant with traditional medicinal uses. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
