Native to the mountains of Europe. Form tightly packed rosettes of fleshy, evergreen leaves; spread by little offsets that cluster around parent rosette. Clustered, starshaped summer flowers in white, yellowish, pink, red, or greenish; pretty in detail but not showy. Blooming rosettes die after setting seed, but offsets (easily detached and replanted) carry on.Many species, all good in rock gardens, pots, even in pockets in boulders or pieces of porous rock.
