A unique, densely carpeting groundcover with fine white cotton like threads between the leaves tips that form a cobweb appearance. Aptly called “Cobweb Buttons” this plant is one of the many sempervivums in cultivar today. The green leaves can change colors with the seasons to a deep red, almost purple hue. Many sempervivum have the common name, “Hens & Chicks”, referring to the growth pattern of the plant. These sempervivum are easily divided as the new growth forms around the “hen”, motherplant, with the “chicks” popping up around it. Extremely hardy cultivar tolerating temperatures well below freezing, plant in rock gardens to fill in crevasses, containers, or an excellent application for living walls.
