Long popular as a rock garden or wall plant, this low, sprawling herbaceous perennial is native to the mountains of Europe. From late spring into summer it bears clouds of small, starry, rose-pink flowers on purple-flushed stems. The dainty, oval, mid-green leaves are concentrated toward the center of the plant. Several cultivars are available, including white- and red-flowered selections. They do not come true from seed and should be propagated from cuttings.
This sun- and lime-loving perennial prefers ample light, good drainage, and neutral to alkaline soil. Plant it in the rock garden, or where its lax stems can trail down a wall. Severely prune its flowering stems after bloom, to improve appearance and prevent self-sowing.
