Camellia caudata is flowering in the greenhouse

This turns out to be a very pretty plant in flower. Frankly I know nothing about it and cursory research doesn't tell me much. There is an entry in the Flora of China. If my Chinese geography was better I'd have a better idea; it looks like it comes from warmer climates than ours. It's flowering now in a cool polyhouse. The low temperature is 34F (the heat comes on at 33). It seems perfectly happy with the temperature.
