Scented geraniums in unheated GH

Ewing, KY(Zone 6a)

Will scented geraniums survive the winter in an unheated PVC house? Thanks any help appreciated.

Surry, VA(Zone 7b)

Mystic, I'd put a thermometer in the greenhouse to monitor the temps and then I'd also email or call a nursery to find out what are the lowest temps that your scented geraniums can withstand. We are going to place black painted water-filled bottles to help conserve heat in the greenhouse we just bought. I hope this helps a bit. Carol
