Easily grown in organically rich, consistently moist to wet soils in full sun to part shade. Grows in up to 3†of standing water. Use containers for water garden plantings in order to control spread. For streams and ponds, place new plants directly in the soils of muddy banks at the water line. Plants will spread by creeping rhizomes but are not overly aggressive. Pinch young plants to promote bushiness. Plants will self seed. If additional plantings are desired, divide plant rhizomes in early spring. Stem cuttings may be taken in summer.
