Adiantum pedatum - Northern Maidenhair Fern 
This stunning, ornamental fern will bring airy texture and bright green color to your woodland garden. Easily grown in moist, rich soils, this fern will spread by shallow rhizomes to form a dense groundcover.
 
The delicate green fronds are balanced on a thin glossy black stem and will spread out in a sort of horizontal spiral. While this happy little fern can tolerate some sun, it really performs best in a shady, cool spot. Groups of the Northern Maidenhair Fern would make a lovely edge for a woodland path.
