Description

Sempervivium calcareum is a succulent perennial plant, up to 6 inches tall. The symmetrical, dome-shaped rosettes of this hardy perennial are densely packed with numerous pale green, blue-tinged, tongue-shaped leaves with pointed, often maroon-stained tips. The rosettes multiply via short-stalked offsets to form dense mats. In summer, some older rosettes bear clusters of starry, yellow-eyed, pale pink blooms on thick stalks with clasping scale-like leaves. Rosettes that flower die soon thereafter.
