I have one area of shade in my garden, right along a fence, and it has been fun to pick and choose which plants might do well there.
Japanese forest grass really stands out in a shade garden and provides interest right through the fall.
Astilbe and coral bells are easy to grow and add lots of color and texture to a shade garden
Columbines and bleeding hearts are beautiful, although I don't always have luck with columbines and am still waiting for this white bleeding heart to bloom
Brunnera "Jack Frost" is another great shade perennial
Shade gardens really benefit from a variety of ground cover like lamium, wild ginger, and sweet woodruff
And let's not forget hostas and ferns: Hostas offer great color and variety, and ferns add much-needed light and airiness to a shade garden
Enjoy your shade!
