I live in an elevated house that has a laundry room on the bottom floor. Every plant that I do not think can survive under 35 I put them in there. To prevent frost I move the plAnts under the house or put them in our hangar. The rock in salvia weren't looking so good beginning of winter, but they have really taken off. I might have a problem with room this year since right now I have the saucy salvia and those can get pretty large, but supposedly can't handle the cold too well. Red Porter weed is one that I do not believe can even handle 36f.
