The garden camelias faired better as their roots where able to go deeper down into the unfrozen earth to get moisture.

The prognosis is not too good and I wouldn't be too surprised if it does dies over the next few weeks as the temperatures start to rise.

You did well moving it to a shadier spot though, but really really be careful with the watering as it's not going to be taking alot of water in atm due to root damage and the extra compost of the repotting, just keep it bearly moist, and try to keep it from too much rain.

Good luck!
