Sempervivum tectorum 'Royanum' is a mat-forming succulent with rosettes of fleshy, yellowish-green leaves with purple-pink tips. The rosettes grow up to 4 inches (10 cm) in diameter.
Flowers are star-shaped, reddish-purple, and held in flat-topped terminal clusters on a stout, upright, leafy, up to 8 inches (20 cm) tall stalk. The rosette dies after flowering but is replaced by offsets on stolons.
Sempervivum tectorum 'Royanum' is a cultivar of Sempervivum tectorum.

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 gently tamp the soil so it is firm in the ground. Water lightly, but you don't need to water newly planted Common Houseleek daily, as 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 germinating. Once they sprout, spread some fine gravel around them as mulch. Seeds are usually started in pots and then transferred to the garden as seedlings. You can sow your seeds in the fall and transplant them in the spring.
Common Houseleeks will spread by underground roots. Each plant multiplies by at least 4, in a growing season, by producing tiny 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.
