Cobweb Houseleek
Cobweb houseleek is a very small plant that grows in a clump of small rosettes. The mid-green to red leaves grow in a tight set of circles, with white threads crisscrossing between the leaves. New rosettes will grow from the parent plant, connected by a stem, and form a colony.
Pink flowers bloom on a short stalk, after which, the individual rosette dies.
Cobweb houseleek is an interesting plant to tuck in spaces between boulder walls, stepping stones or rock gardens.
