The creeping selections of Stonecrop are excellent groundcover plants, particularly for hot, dry sites. This species forms a low carpet of tiny round powdery blue-grey leaves, remaining evergreen in mild regions. Clusters of white star flowers appear in early summer. A fast grower, this is best kept away from slower alpine plants. Takes on a mauve cast during cool weather. Mow or clip back in spring if desired. Has potential as a lawn substitute and for use on green roofs, as well as in rock walls, rock gardens and containers. May well prove to be hardy in Zone 4 or colder.
