Wine cap mushrooms, currants, American persimmon, hazelnuts, comfrey, Nanking cherry, elderberry, black raspberry, lots of great stuff grows in the cold north! Iโm excited for you! I started my first food forest last year in zone 6 and itโs been an incredible
experience for me! Try tuning in on edible acres .org on you tube, I believe theyโre in upstate ny with similar conditions as you!
