Athyrium

Lady ferns are members of the Aspleniaceae family. The Greek derivation of the scientific name is athyros means doorless, which refers to the slowly opening hinged indusia.  The common name lady fern refers to the delicate lacy-cut fronds.

The most commonly cultivated native species in North Carolina is the southern lady fern (Athyrium asplenoides).  This fern is found in all 100 counties of NC with the exception of the barrier islands.  Pinnule margins in this species vary from shallow to deeply toothed and often become double toothed toward the base of the pinnule.

The foliage of lady ferns is unique as it adds a unique lacy-texture and appearance of softness to the garden 

The native range of this genus is cosmopolitan.  These ferns prefer rich, moist well-drained soil but are relatively low-maintenance and tolerant of dry conditions.  They may be used as specimens, groundcovers, accents or cover for wildlife. If planted near buildings, they will often do better on the north to east side.
