Depending on how much shade/sun...a few are lagerstromia, acer palmatum, cornus kousa, stewartia, magnolia virginiana, amelancier laevis. All have varieties thqt will not get over 20-25 feet. Depends on amount of sun and drainage.

any tree you plant will have a somewhat large root system. the roots of tree go out 2-3 times the height of the tree. so a tree that is 20 feet tall can have roots 40-60 feet spreading out in a 360 degrees.
