You are most welcome, I am happy to help
It shouldn't be too big a problem, as Frostproof is hardy to zone 7, (0 to -10 degrees) and marginally hardy in zone 6 with some protection. I would ask around and see if anyone else in zone 7 grows Frostproof and how it has performed for them. That is one of the reasons I have it, as a late frost has damaged some blooms and caused them to fall. FrostProof won't. Give these links alook.
