trees

I'm shopping trees this winter.... plans for spring. I have some shade in the back and I figure if I can just keep it watered and not stay so dry dry dry all summer, maybe a few trees will have a shot. I had my eye on a coral bark Japanese Maple at the home and garden show a few weeks ago. and then I came across a pawpaw tree in a catalog and thought that'd be nice to try also.
Only other tree I'd like to try and grow if I had a place to put it is a Japanese Persimmon tree.
Another tree on my consider list is a Redbud tree, the variety "Pauline Lily."
