Don't know what part of state of Ohio you're in but if you are in my general area drought tolerance should be a consideration. As should disease tolerance. There are some great new tolerant cultivars on the market now I have had success with. Although there is no such thing as a drought tolerant tree in the first three years while establishing a fibrous root system. Water bags (Gator, etc) work real well. Religiously follow planting and maintenance procedures as described above. I would add make sure mowers and weedwackers stay well away from base (mulch or protection stakes) and in early fall put 3 five foot high stakes outside root ball then put some temporary fencing attached to them to keep the long legged rats (deer) from rutting on them and destroying them. It WILL happen.

If you want to attract hummingbirds, pink or reddish flowers of the crabapple or Buckeye etc. or shrubs as you mentioned seem to work as well as some pink colored sugar water in a clear hanging container.
