In northern New York, wild apples, wild strawberries, raspberries and blackberries and blueberries; fiddlehead ferns in early spring; mushrooms are iffy, but there are puffballs, and those things that grow off the side of a tree like half a disk, and morels which are safe because they don't look like anything else; St. John's Wort, a five pointed yellow flower which I just like to pluck and chew to improve my serotonin in the brain; dandelion greens all summer long; violets; buds and blossoms off of day lilies; cat-tail parts; wild asparagus; milk-weed pods which have to be boiled about three times. There are many books about harvesting wild plants, the original of course was Eull Gibbons "Stalking the Wild Aparagus." Good luck and be safe.
