Description
Sempervivum arachnoideum is a low-growing perennial succulent that forms rosettes of green leaves flushed with red and white hairs connected at the tips. It grows up to 3 inches (7.5 cm) tall and 12 inches (30 cm) wide. The rosettes grow up to 1 inch (2.5 cm) in diameter, forming dense mats.
The flowers are pink, star-shaped, and appear in summer.
How to Grow and Care
Relatively easy to grow in a container or a rock garden, scree bed, wall crevice, trough, or alpine house. After the plant blooms and sets seed, it will die, but many offsets will take its place. Plant in well-drained succulent soil mix in full sun to light shade. Water regularly during the growing season and allow the soil to dry out before watering again. Water very little during the winter months.
Sempervivum arachnoideum can get vine weevil and may be subject to rust. Propagate by seed sown in spring or root offsets in spring.
