Grow in medium to wet soils in full sun to part shade. This iris may be grown in up to 2-4″ of shallow standing water (muddy bottom or containers), or in moist shoreline soils or in constantly moist humusy soils of a border. Propagate by division after bloom. Wear gloves when dividing the rhizomes. After fall frost, plant leaves may be trimmed back to about 1″ above the crown. Will naturalize to form colonies in the wild.
