For the purposes of maimizing the diversity and edibility of our lands, I thought it would be great to make a list of every edible tree or bush I can grow here. I am in zone 5, hence the title. I am thinking of trees and bushes that can grow in this climate with little in the way of extra attention because I don't have time for that. Please help me make this list complete. I realize this list will be extremely long, we will have to keep adding to it when we have time. I am just putting a few on here to start.

Hackberry Mountain Ash American Linden (edible leaves, flowers and nutlets)
Black locust (edible flowers)
Maple trees (edible samaras and sap=syrup)
Elm trees (edible samaras)
Wild black cherry
Wild American plum Grapes - riverbank grows wild but there are many great cold hardy varieties - bluebell, niagra and somerset are reliable
Staghorn and smooth sumac
The bush cherries - romance series are tasty
Wild dew berries
You may want to look into the edible perennials too and some wild perennials.
Pretty much every single plants that nurseries advertise to grow in USA will grow in zone 5.
It is easier to make a super short list of which plants will not grow in zone 5.
(Banana, Avocado, Coconuts/Palms, Pomegranate, Macadamia Nuts, Olive, that pretty much it)
Another category to remember is the relatively short list of trees and shrubs that bear edible foliage. The lindens, sourwood, and rose-of-Sharon come first to mind, perhaps there are others? The way to manage these plants for leaves is to coppice them in turn, so there is always new growth near the ground to harvest.
