This is a lovely delicate sempervivum, with rosettes covered with fine, white threads which crisscross between the leaves' tips like a cobweb. Each rosette of pointy, blue-green leaves grows about 1 inch wide. The color can vary from season to season, with unusual rose-red flowers produced on leafy stalks in midsummer. Plant grows no more than 4 inches tall, and 8 inches wide.
