Small tree for Shady back yard
I am looking for a small tree or a shrub I can train to a small tree to give some height in my back yard. I would ideally like something that is 10-15 tall and about the same width. My yard is small with a 5' privacy fence around the perimeter. The yard is fairly shady little direct sun but not dark due to a neighbors elm.
I like Japanese Maple however the folks at Bachmann's and Gerten's have dissuaded me from this beautiful zone 5 tree. I wonder if I could train an elderberry to a tree form or if there is some other tree or shrub that would work.
