Tree ID

Is this leaf from a Montmorency cherry seedling or maybe a chokecherry? It's only about 30' from the Montmorency, but I think the leaves are wider. They seem pretty similar though. It's in a great place for a new cherry tree and my old tree isn't doing too well.

Are you sure itts not a sucker ? No not you but a new cherry tree growing from the roots of the other cherry , it's very common in cherries . So if your cherry is grafted then it's a cherry of the root stock .

It seems pretty far from the old tree to be a sucker? The old tree is is only 15' tall and 10' wide and 30 feet away I haven't seen any suckers in the lawn in between. Maybe a couple by the trunk. I'm sure it is possible. Would a sucker be more likely than a seedling? We have some wild cherries in the area. Choke cherries, I think, maybe others.

They don't seem to come up under the tree from seeds. I thought that might be some kind of allelopathy? Pretty sure that's spelled wrong.

Could be, not certain, that the roots tried to come up in the lawn but you cut them without seeing them the tree would just keep on going until it could grow without getting chopped  

Hopefully, these will help.
