Should be grown in humusy, medium moisture, well-drained soils in full sun. Best flowering and disease resistance occur in full sun, however plants will tolerate light shade. Good soil drainage is essential to combat potential soft rot problems. Avoid use of mulch for the same reason. Heavy clay soils must be amended prior to planting (e.g., add gypsum, coarse sand, organic matter) or raised plantings should be considered. Plant rhizomes shallowly (cover with 1/2” soil) and 12-24” apart in mid to late summer (July to early September). Fertilize lightly in early spring. Avoid overhead watering. Deadhead individual spent flowers and remove flowering stems to the ground after bloom. Divide plants immediately after flowering when overcrowding occurs (every 3-4 years).
Best in sunny beds and borders. Will naturalize into large clumps.
