Plumeria!!!!!! If you smell this, you will want to make room in your home for a 'tree' in the winter.
I thought I was growing Brugmansia for the scent. For years I read about how wonderful the fragrance is, but apparently it's only scented when I'm in the house for the night, and starts blooming so late in the season, windows are sometimes closed already. Hard to waft in the house that way. The few times I've ventured out to be eaten by mosquitoes while I sniff, I wasn't impressed with the fragrance at all. I'm not going to get rid of them, but need to move them. I want something in that spot that will waft really amazing fragrance into the house when people are awake.
