Cobweb Houseleek
Sempervivum arachnoideum
Sempervivum arachnoideum, the cobweb house-leek, is a species of flowering plant in the family Crassulaceae, native to European mountains, in the Alps, Apennines and Carpathians. Growing to 8 cm (3 in) tall by 30 cm (12 in) wide, it is a rosette-forming succulent perennial, valued in cultivation for its ability to colonise hot, dry areas via offsets.
The specific epithet arachnoideum refers to its furry central rosettes (long ciliate leaf margins), resembling spider webs.
