Quick Overview:

Thelypteris palustris, commonly called marsh fern, is a deciduous fern that is native to rich muddy soils in open woodlands, marshes, bogs, wet meadows, and along ditches and streams in Canada (Newfoundland to Manitoba) and the eastern and central U. S. (Maine to South Dakota south to Florida and Texas). Light green upright fronds spread by rhizomes into colonies. Excellent for foundation plantings, and under shade trees. Naturalizes with other understory natives in wild gardens. Equally at home in wet or dry shade. Herbaceous.  (Courtesy of Missouri Botanical Garden Plant Finder)

Easily grown in moist to wet soils in full sun to part shade to full shade. Tolerates full sun if soils are kept consistently moist. Prefers fertile, moist, humusy loams that are rich in organic matter. Soils should not be allowed to dry out. Avoid standing water. Site in locations protected from strong winds to prevent damage to the fronds. The old fronds should be cut off in late winter prior to the emergence of the new growth. Propagate by division or spores. Spreads by rhizomes to form colonies.  (Courtesy of Missouri Botanical Garden Plant Finder)
