Like other sempervivums, it's a low growing succulent that forms dense clusters of rosettes, with the main "hen" producing smaller "chicks" around it. It's extremely drought tolerant, cold hardy, and perfect for rock gardens, containers, or as groundcover in sunny, well drained areas. Type: Succulent Height: 0. 75 Spread: 0. 75
