Gardenias, O. Fragrns, Camellia, and Winter sweet all survived14F
We had one night that dropped to 14F. I was worried the plants that are cold hardy to zone 7. However, they all survived very well without any damage.
Those photos were taken after the cold snap. The first one is O. Fragrans. (don't know the name as I bought it from local Lowes. I guess it is Fudingzhu. It is a 4 season one. Fragrance is weak). The second photo is Gardenia. (don't know the either. Lowes product as well. It looks like a Chuck Hayes)
