Sempervivum tectorum is a mat-forming succulent with rosettes of 50 to 60 fleshy, green, sometimes purple-tipped leaves. The rosettes are up to 4 inches (10 cm) in diameter. Leaves are glabrous and up to 3 inches (7.5 cm) long. The mother rosette spreads in all directions by horizontal stems to form offsets. In summer, leafy, pubescent, upright, up to 12 inches (30 cm) tall flowering stalks rise from the mother rosette topped with cymes of red-purple flowers.
USDA hardiness zones 3b to 11b: from −35 °F (−37.2 °C) to 50 °F (+10 °C).
How to Grow and Care
Common Houseleek can be grown from seeds, seedlings, or by dividing offsets.
Don't plant your Common Houseleeks too deeply. Dig a shallow hole and spread the roots. Cover the plant's crown and tamp the soil gently so that the plant is firm in the ground. Water lightly, but you don't need to water newly planted Common Houseleek every day, the way you would with non-succulents. Common Houseleeks need to let their roots dry out between waterings.
Seeds can be sprinkled on top of a soil, gravel mix and kept moderately moist until they germinate. Once they sprout, sprinkle some fine gravel around them as mulch. Seeds are usually started in pots and then transferred to the garden as seedlings. You can start your seeds in the fall and transplant them in the spring.
Common Houseleeks will spread by underground roots. Each plant multiplies by at last 4, in a growing season, by producing little offset plantlets all around the perimeter of the "hen." These are the "chicks." The chicks can be snapped off and replanted elsewhere at any time.
The juice and leaves have been used in folk remedies for centuries for their coolant, anti-inflammatory, astringent and diuretic properties. Bruised leaves of the fresh plant or the plant's juice can be used as poultices for burns, scalds, ulcers, and any inflammation as the pain is quickly reduced. Honey, mixed with the juice, helps relieve the pain of mouth ulcers.
