Back on the West Coast we call em Huckleberrys, If they are,They are great eating, my wife made the best pie's from them I ever ate, Taste sorta like blue-berrys but more mello ! just my 2 cents Capt Bob
I don't know what they are, but those are not the same berries we called huckleberries growin up in NW Louisiana. The leaves were much smaller and the berries did not grow in groups like that. Maybe do a search for Black Cherry (Prunus Serotina) I think you will find what you're after.
Thank you for the help. I have this large tree in the back that is about to be cut down and have always wondered if the berries were edible. May have to harvest a crop (if wild cherry)and see what I can make of them before the city gets to it. Thanks again.
