Question: what is the plural of Sempervivum? Anyway, the houseleeks all form tight rosettes of fleshy leaves, each rosette producing a number of offsets each year, so that a spreading, tight mat soon forms. After a few years a rosette may decide to flower, in which case it sends up a short stem, topped with a cluster of flowers, pink or yellow. It then dies, its place in the mat taken by youngsters. There are hundreds of named varieties, of which we offer some of the more distinctive ones, including some new varieties, bred by the late Matthew Ruane at Brynhyfryd Nursery. See also Jovibarba.

Sempervivum 'Black Mountain' has distinctive rosettes of bright green, with clear red edges to the leaves - or, if you prefer, red rosettes with green centres,
