Description

This wildflower grows naturally in bogs, marshes, and wet areas. It can grow in loamy soil in garden areas where water is adequately applied. It prefers wet soil but will tolerate dry and once established is quite drought tolerant. It grows in full sun to part shade with the more sprawling habit in fertile soil or in too much shade. Taller plants may need support.  The interesting foliage and flowers are great in cut and dried arrangements and can make this a specimen plant in your garden.  Or plant in groups in low spots, near water gardens, rain gardens, ponds, or in borders.  It naturalizes easily through seed.
