I am years late coming into this discussion, but I would like to add that a particularly lovely night-blooming plant which smells just like cotton candy is Zaluzianskya capensis
"Night Phlox"
AKA "Midnight Candy".
I used to have one in my garden (Central California), in a large ceramic pot. It is not a large plant. Lovely white flowers. My plant lived for years. The scent it gives off at night is wonderful. The only place I know to obtain Zaluzianskya capensis is through anniesannuals.com ------ a nursery based in San Francisco. anniesannuals sells the most wonderfully pretty and unusual plants, via catalog.
