Description

Eastern Marsh Fern is a native fern in the marsh fern family.  It is found in low woodland areas along riparian corridors and roadsides.  It has a low creeping rhizome from which arises erect to arching fronds. Only Thelypteris palustris available in the trade.

The plant prefers full sun to partial shade but not deep shade and moist but not too wet sandy soils. It will adapt to other soil types readily. Use in the woodland garden, along ponds or water gardens.
