Sempervivum Arachnoideum Cobweb

'Cobweb' consists of small, tightly compact heads of succulent green leaves with criss-crossed white hairs. Rose red flowers appear in summer. Sempervivums, also known as Houseleeks or Hens and Chicks, are succulent perennials that form rosettes of succulent leaves that will often spread fast to form mats. They tend to spread rapidly in favourable conditions via offsets and are valued as a ground cover for dry, sunny locations. Their ability to store water in their thick leaves allow them to live in sunny and rocky places through out mountains. Most are hardy to US zone 4, and will handle warm climates to about zone 8. Sempervivum grow as tufts of perennial but monocarpic rosettes. Each rosette propagates asexually by lateral rosettes or offsets. Typically, each plant grows for several years before flowering. The colour of the flowers is reddish, yellowish, pinkish, or seldomly, whitish. In Sempervivum, the flowers are actinomorphic (like a star) and have more than six petals. After flowering, the plant dies, usually leaving many offsets it has produced during its life. Sempervivums also make suitable plants for containers, and do well in breathable terracotta, concrete, and cement pots. They have also been known to grow in rock crevices, metal containers, succulent wreaths, roof shingles, and anywhere else that allows adequate root drainage.
