The Cinderella line were the first lisianthus I tried. I agree the pink are stunners!
Bluebells are not something I have grown from purchased seed, but I did buy rhizomes from one of the cheapo mail order companies years ago, and they self seed like crazy, I have tons of them now. I agree they are lovely in the spring. Since they self seed so readily, I would expect them to be a great candidate for winter sowing.
