Of course you can toss a light blanket over your Camellia every night when needed, removing it after the temperature warms in the morning. Snow flurries predicted here on Thursday night! All the plants in my yard are shivering.

Yeah, what is with this cold weather?
I'm so disgusted.
I live in South Carolina too, my poor gardenia's little leaves are chattering.
Don't worry that much about your camellia though, it'll probably be fine.
I myself wouldn't cover it, I'd be afraid that I would knock the buds off, but that's just me.
I can't wait til it warms up a bit.
Geeessshhhh!

Thanks for the help! I've put a sheet on it, and am hoping that will help. I moved here in 2005 from Florida, and I like the cooler weather, but this is just silly! I'm looking forward to the 50's they're forecasting for next week.

Seachellelee,
In case your interested, there is a camellia show in Aiken Mall this Saturday and Sunday.
Across from Bed, Bath and Beyond.
There are going to be 1000 camellia blooms and also Bonsai.
Stop in if your interested.
I think most people that go to the show have their camellias in a greenhouse. I hope so for their sake.

There were some Great tips for protecting your camellias from the cold in the January 2010 issue of the Camellia Gardener E-News Magazine. See the link below.
