(also known as Tatting Fern,
Lady Fern & Southern Lady Fern)
Athyrium

Description:
All of these varieties enjoy moist shady locations, some will tolerate some sun if the soil is very moist as on the edge of a pond or stream.  With their open texture and graceful appearance, ferns make a wonderful counterpoint to flowering perennials.
