edible plant in zone 5
I have recently moved to the chicago area and have bought a house that is perfect for gardening and landscaping. I love working in my yard and would like to use mostly edible plants in my yard. I feel I should enjoy the fruits of my labor (literaly) I know of some blue berry and cranberry bushes that I'm useing for ground cover and I want to plant a stella cherry tree. What other fruit bearing plants should I consider in this climate?
