Sempervivum Calcareum 'Greenii' is a frost hardy hens and chicks succulent from the Crassulaceae family, native to the limestone mountain regions of southern Europe. It clusters naturally across rocky, well-drained terrain and spreads through offsets.
It forms tight, symmetrical rosettes with fleshy, blue-green leaves tipped in reddish-purple, creating a two-toned contrast across each plant. Individual rosettes stay compact, typically 2 to 4 inches across, with smooth, slightly glaucous leaf surfaces. As it clusters outward, it produces small offsets called chicks that fill in surrounding space.
Each rosette flowers once in its lifetime, sending up a tall stalk with star-shaped pink to reddish blooms in summer. The flowers produce pollen and can trigger mild allergies in sensitive individuals during bloom season. After flowering, that rosette dies back while the surrounding chicks continue growing, keeping the plant full and established.
Move it outside in summer or leave it outdoors year-round in its hardiness zones. It handles balcony wind and rain without trouble and tolerates dry heated indoor air. Tuck it into rock gardens, alpine troughs, container arrangements, or use it indoors under rotating placement for even rosette development. It is pet friendly and historically used in folk herbal medicine.

Sempervivum Calcareum 'Greenii' grows well in partial to full sun and tolerates lower light indoors with regular rotation for balanced rosette growth.
Water it deeply every 10 to 14 days, allowing the soil to dry out completely between waterings.
Sempervivum 'Greenii' does best in a gritty, fast-draining succulent or cactus mix combined with perlite or coarse sand to prevent root rot.
It prefers temperatures between 65 to 80 degrees Fahrenheit and is frost tolerant, surviving well below freezing with proper drainage.
