Growing to just {{convert|10|cm|in|abbr=on}} high by {{convert|50|cm|in|abbr=on}} wide, it is a spreading evergreen perennial. It forms spheres of pointed, succulent, hairy grey-green leaves. Mature rosettes may produce yellowish flowers on stalks up to {{convert|10|cm|in|abbr=on}} in summer. Despite a superficial resemblance, houseleeks are not closely related to cacti. The Latin specific epithet ciliosum means “with a small fringe”.[2] Sempervivum ciliosum has gained the Royal Horticultural Society’s Award of Garden Merit.[3][4] Although hardy down to {{convert|-20|C|F|abbr=on}}, it requires a sheltered position in full sun, in well-drained soil.
