Thelypteris noveboracensis - New York Fern
Has light green foliage, which grows from a running root system. This is a good spreading fern and will tolerate dry shade. Tends to turn brown in late summer if it gets too much sun. Fronds are tapered at both ends. Often seen in thick patches under pines or hemlocks which is very dry and very acid, a very tough fern. Be careful when putting mulch on or around these as too much mulch will smother them out.
Shade to Semi-shade, Dry Soil, 12-18 in Tall, Zones 3-8
