I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
Natchez is a good variety for your purposes, and the cinnamon colored exfoliating bark is very attractive. There are other tall growing crape varieties but not with white blooms and that have such attractive bark. I suggest you remove the bloom buds from some of the upright central branches as they are developing. Any long shoots growing out to the sides should be removed where they attach to the branch. This way you can train them upward and build a more upright tree over time.
Thanks for the question. Please stop in again soon!
