Much of the time you will get advice on shade with cultivated plants in mind. The suggestions are often slim. Parsley and Rosemary are both great. I have partial shade in my back yard and have recently added currants and gooseberries and Alpine strawberries. However I have looked into more wild and native plants not typically found in the super market and it provides more opportunities. Even weeds like Lamb's quarter and wood nettle can make fine edibles and they have more nutrition than kale or spinach. I plan in the future to try these along with wild ramps. They just can't do the commercial food chain but they grow like weeds. I have already planted Pawpaws and Saskatoons and I am in the process of planting Nanny Berries. All these are great native under story trees and as already mentioned the high bush cranberry is another(make sure it a native variety of either Viburnum Edule or Viburnum Trilobum which is supposed to have better fruit than the Euro).
