I have located a web site that claims to have developed crape myrtle to be winter hardy by raising them in Pennsylvania.
I live in zone 5 and believed it to be too cold to confidently plant crape myrtle. Any input?
I visited the link you sent (thanks!), and they claim Zone 5 would be OK.
I'm still a bit leary, I'd ask if there's a warranty of some sort.
If you decide to give it a try, please let me know how it works. I know some professionals who have tried to grow crape myrtle as far north as central Illinois (also a Zone 5), but without success.
