Thanks for all of the suggestions and help identifying these trees. I have only lived here a little over a year and am finding I have .56 acres of "where do I start". Any and all help is greatly appreciated. Per request here are twigs from the first two plants. Ignore the numbers and letters written on the paper. I lost a brain cell somewhere in the process and messed them up. This first photo is from the mature tree: The next two are from a juvenile tree: The smaller twig in this photo is from a juvenile tree. The larger from the mature tree. I think I have two more questions: regarding these cherry/elm trees. The juveniles are popping up on the opposite end of the yard away from the house. Is there any particular reason why I shouldn't let them just grow? WIth the exception of a large flower bed in the middle of the yard and all the trees jammed in at the border of the property my yard is pretty much a large expanse of lawn. It would be nice to have a few more trees! And as far as the poplars go, there is a dirt road that comes up beside one side of my house. I'm thinking these might be a good privacy screen for that side of the yard. How well do they transplant? Thanks so much!

I'm thinking that the first tree is some sort of Locust ("Twisty Baby" or something like that???). I've seen it being sold at Farmington Gardens. The second looks like the Golden Curls Willow. I have one in my yard.

Definitely a Paulownia anyway. Although P. tomentosa is dominant in western cultivation other species have also been circulated in later years. These are told apart by things like details of the inflorescence structure and hairs on the leaves.

It's rubra. I have that leaf etched in my mind. Agree with Embothrium.... last years acorn caps on the ground or full acorns in combination with leaf is key to identification for most folks. The most serious of folks and experts know the buds, too. Dax
