Populus sp. to be sure.

Thank you. I've read that their cotton isn't really an allergen but it certainly is messy.

Ken, as you know, I'm in Adrian, also. If I didn't know better I would think it were November. I hate them. If the top photo, enlarged, doesn't give scale enough, then I don't think anything will help. What do you need? A Pepsi can next to a leaf?

These look like Eastern cottonwood trees there a poplar a relative of willow. Poplars are not all bad they do have some redeeming quality's but not many same with willow. Poplars can get rid of standing water so can willows if you want to get rid of water these trees can help there also good wind breaks and good for shade. How ever there short lived and diseased prone and soft wooded. wood makes good crates and boxes and pulp wood. If these trees are in a good spot there fine but to close to house ,sewer,septic,well then your asking for trouble. Cottonwood lives 70-120 years usually sometime they have been known to live 200-300 years.

From the looks, they couldn't be anything BUT Populus deltoides!
