RE: What grows in extreme shade?
Some of my plots are trails or logging roads on my property. They will get some sun but not alot. Try planting anything you want, you might be surprised on what will grow. It might not grow to its full size but your not harvesting it anyways. I always get turnips and clovers, This past fall I put in some winter wheat and with the leaves coming down it opened it up enough that I had a good growth of wheat for the fall and winter.I do have one small area that no sun get to at alland I plan on doing some trimming of branches so that I can get something to grow so the trail does not erode away. What I'm getting at is you don't know what will grow if you don't try. My turnips may not get 4" in dia. but a 2" turnip is better than nothing and it's for the deer.
