Sempervivium calcareum, the houseleek, is a succulent perennial plant that is native to the southern Alps. It has a rosette with thick leaves that store water. The leaves are usually green with reddish-purple tips. This plant reproduces with asexual budding and monocarpic sexual reproduction.[1]

Sempervivum calcareum is cultivated as an ornamental garden plant. It is suitable for a well-drained spot in full sun, such as a rockery. The cultivars ‘Extra’[2] and ‘Guillaume’[3] have gained the Royal Horticultural Society’s Award of Garden Merit.[4]
