    Love the common name....very Gothic. Spun cobweb-like filaments adorn the fleshy rosettes, adding an interesting textural display. This hardy Hens and Chicks really needs excellent drainage to be happy....think crevices in a rockery or stone wall. Height is under 4' and spreads by offsets where happy.

    Sempervivum Cobweb is named for its unusual web like covering. Cobweb is about one inch wide by three quarters inch high. It produces tiny off shoots at its base looking much like chicks hiding under a hen’s wings. In time the mother plant will bloom with beautiful rose pink blooms on a thick upright stalk. Then the mother plant fades and dies while the chicks gather strength and grow on to continue the process of new life. The chicks can be pulled up most any time during the growing season and planted in a new location. Excellent in rock walls, between pavers, containers troughs and any site in full sun with good drainage.

    Cobweb with medium sized freely offsetting rosettes, presumable the webs scare off insects looking for a meal; Ender loves the spider web without the spider concept and has planted these all over our rock garden. Thankfully, his taste improved, he discovered Kab Saxes later in the summer (he planted his own tufa trough, its quite nice). Ender says to remind you they are monocarpic and have a really weird scape.
