Best grown in moist, organically rich, well-drained soils in full sun. Rhizomes may be left in the ground in USDA Zones 7-10, however in the St. Louis area (Zones 6a-5b), the rhizomes should be lifted in fall for overwintering. Plant rhizomes 4-6” deep and 18-24” apart in spring after threat of frost has passed. Remove entire flowering stems immediately after bloom. In fall, cut plants to the ground after first frost and lift rhizome clumps for winter storage in a dry medium (peat or vermiculite) in a cool dry location than does not fall below 40°F. Rhizomes may be occasionally sprayed with water in winter to make sure they do not become so dry that root shriveling would occur. Container grown plants can be stored in their containers in winter. Propagate by division in spring before replanting outdoors.
