Narrow, stiff, evergreen leaves grow in compact tufts or basal rosettes; small white, pink, rose, or red flowers are carried in dense, globular heads. Main bloom period is spring to early summer, but shearing off faded flowers may prolong flowering. 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.
