I have a tree in my backyard that I have yet to Identify. I have check all the tree books for my area, and even general ones on the internet with no answer. Forgive me if I use the wrong terms, or sound like an idiot. It is the same height as my two store flat, so I know it is no bush, but it has blackberry like fruit on it. The tree bloomed earlier this spring with small white flowers and within a few weeks there were small green fruit that turned to black. Someone could take these berries put them in a small crate and I wouldn't know the difference between them and the blackberries I buy at the market. I tasted one (I know, not smart) and they have the flavor of a watered down blackberry, almost grape like, and it didn't kill me or make me sick. The foliage is a very dark green, and reminds me a lot of a black cherry's leaves. Just broad, simple, leaves that come to a point at the end. The back is dark and rough around the trunk but becomes pale and smooth on the outer branches and upper parts of the tree. This tree is growing in southern Indiana, and does loose it's leaves during the winter. I would just like to know mainly what kind of berry it is, and if it is truely edible. They are quite tasty, and I would like to eat them before the birds eat them all if they are safe. If anyone has a question I will be happy to answer it, or maybe you can answer mine.
