Our winters have been mild also, for the last couple of years. Although the 'Farmer's Almanac' is calling for a very cold winter this year. It's my second year having a E.oxypetalum, and I'm trying to decide what to do with them…Currently they are on a covered deck…So I'm not concerned with frost…But low temps are my concern now. I'm thinking that either indoors, or at least a cover will be called for if temps drop to freezing. And as I write this, I doubt that a 'cover' would be enough! I guess I need to start thinking about where they'll live indoors!
