When I moved to my place, I figured I was only 6 miles to the ocean, and should be able to grow semi-tropicals.. I bought several new Brugmansia cultivars in the fall, only to have them turn into mush with the first cold snap. I don't think it's any colder here than it was at my last house, but the cold stays longer... Things freeze... I love brugmansias.. Great scent.
