Sue, that's disappointing. I've wanted to grow a Crepe Myrtle too, and we would have the heat and humidity to go with it, but it needs sun too, I thought, and I don't have a place to put one really. they are beautiful!
On the other hand, I think a lot of people struggling with the unrelenting heat this summer would give up growing a Crepe Myrtle for a 6-8degree drop in temperature! And you manage to grow a banana! lol
