I've had several butterfly bush plants, but they always die. I'm in South East Florida. Perhaps the weather down here isn't suited to them?

Now that I've gone through all of my photos trying to find decent ones for this page, I'm considering wasting just a little more money and effort by getting another butterfly bush and planting it. My butterflies sure did enjoy the ones I used to have. I'd like to believe that my gardening skills are better, and that I might keep a new one alive, but we're also under watering restrictions (still!) so I'm not sure if I'm going to give it a try or not. I'll let you know...
