WINTER HARDY MIX Sempervivum Seeds A wonderful collection of evergreen, carpet forming succulents with thick, fleshy leaves that form small or large rosettes depending on the variety. Plants spread by producing little offsets (chicks) that cluster around the parent rosettes (hens). The clustered star-shaped summer flowers are often rosy-red but can also appear in shades of pink, yellow, white or green. Excellent in containers or rock gardens. Winter hardy to zone 5.
