Winter hardy to USDA Zone 7 with protection. Grow in organically rich, medium moisture, well-drained soils in full sun.
To grow plants in the ground in the St. Louis area, plant rhizomes 2” deep and 6-8” apart in spring after the last frost date. Provide consistent moisture throughout the growing season. When foliage begins to yellow in fall, taper off watering. Lift rhizomes after foliage dies back, dry and store covered in a dry medium such as peat or vermiculite.
For growing in pots or containers, rhizomes may be started indoors in early spring with pots brought outdoors to a sunny location after threat of frost has passed.
Locate plants near patios, walks, decks or other living space so that the fragrant flowers may be enjoyed to the fullest.
