Pat, the ones most susceptible to frost are Trumpets, so those are top priority. OrientalTrumpets are next to freeze The ones least susceptible are the Asiatic and Longiflorum Asiatic, so you shouldn't have to worry too much about those. Everything else is kind of 'in between' depending on how tall it is. The taller they are, the more susceptible they are. Tiny little noses of any type, just barely breaking the surface by a couple cm are usually 'safe'
