I received a beautiful red blooming azalea from a friend when I was in the hospital. It has stopped blooming and I'm pruned the deadheads off and repotted it in a bigger pot and have it on my front porch. Is it possible to plant it in my yard to leave it there? I live in the upstate of South Carolina in zone 7. Our summers are very hot and humid and our winters are unpredictable. Thanks for any help.
