Description
Prefers sandy or loamy, moist soils, but is drought resistant. Spreads slowly by rhizomes. Deadhead to prolong blooming season. Propagate by seed, cuttings and division. Cut back to the ground after first frost and mulch to protect roots for the winter. Outstanding in mass plantings, as a border perennial, or in rock or low maintenance gardens.
