In the mountains of North Carolina, the camellia is having a very good year. Serious. This is not in the low country of South Carolina. You can call it the Lake Junaluska effect compounded by a courtyard micro climate effect and toss in the fact that winter is on hiatus. Some years the camellia buds are known to freeze.
There is a weak snow coming up in the diagnosis for me, but I doubt any of it will fall on these fishies.
