Marsh fern
Thelypteris palustris
This perennial fern has upright compound leaves whose leaflets are often slightly curved and twisted. The root system is rhizomatous and fibrous and can form dense colonies and performs as a wonderfully as a ground cover. Marsh fern prefers full sun to light shade, wet to moist conditions, and a sandy acid soil although it readily adapts to other kinds of soil. It will not tolerate standing water or excessive shade. Foliar disease and insect pests are rarely troublesome.
