Thelypteridaceae

Botanical Name

THELYPTERIS palustris

Plant Common Name

Eastern Marsh Fern

General Description

An attractive, medium-sized, deciduous fern that does well in damp soil, marsh fern occurs throughout much of the middle and upper latitudes of the Northern Hemisphere. Its lacy, erect, pale blue-green fronds spread rapidly via wandering underground rhizomes. Spores are borne on fertile fronds whose segments have curled margins.

This hardy, vigorously spreading, moisture-loving fern grows best in partial to full sun. It is adaptable to most soils that are not dry or submerged. It is perfect for colonizing a sunny pond edge or other wet spot in your garden, or for combining with vigorous moisture-loving perennials.
