A slow spreader, Lady Fern, Athyrium filix-femina , features light green fronds and grows naturally in shady areas.  Good for erosion control and as a ground cover.  
 
     Delicate looking and beautiful in a garden setting.
 
     Fun fact 😁: The clusters of spores on the undersides of the leaves are curved -- like a lady's eyebrow ~ hmmm... (Source: Minnesota Wildflowers)
