@baymule , I’m curious. Do you not think of Corpus Christi as “East” Texas?
You should know that many gardeners would be delighted to have a crepe myrtle in their yard. I have mentioned on TEG neighbors that have a couple in their backyard. Their fence is a 6’ wall. There was a nursery truck in the driveway the other day - not a landscaper, a nursery truck. They are trying to overcome the zone 7 (maybe zone 6) limits.
The trees look good some years peeking over the wall but have taken some winter hits. Maybe they will have an avocado next
