Native to: California, Oregon, Washington, and B.C.
Tufted mounds spread to 1 ft.; leaves are 6 in. long. White to rose pink flowers in tight clusters atop 6–10-in. stalks. Bloom is profuse in spring (goes on almost all year in mildest climates). Sturdy, dependable plants for edging walks or borders and for tidy mounds in rock gardens or raised beds. Attractive in containers. Good drainage is essential and permits regular watering, but safest tactic is to water moderately in dry climates, sparingly in moister regions. Tolerate seaside conditions, infertile soil. Clumps spread slowly and need dividing only when bare centers show.
