Thanks for your guidance, quirkyquercus. A very helpful site.

Well.......... did you find them??

I was able to get Dynamite at Pikes in Acworth this weekend.

waltrrr,

I don't know if you've found what you wanted. Yesterday, I saw Lowe's had a bunch of new arrivals. There were many varieties, but because I was running out of time, I did not go through the whole lot of them. I just grapped what I thought was nice (a couple of Osage). The plants were in 3-gallon pots and they were both 8 footers. All of that for just $12.98 each! Last year, I bought some Sioux, Tuscarora and a Lipan from Home Depot. If you live in an area where you have access to both these stores, maybe you want to try them?

Thanks to everyone for your help in locating a supplier for crepe myrtles. Anyone who finds themselves awash on the same shore need look no farther than http://www.clemson.edu/crepemyrtle/. Regards to all, and many thanks for your assistance.
