Thanks Mike, it will be interesting to see what you find out. I have gotten some hybrid tropical lilies brought in, they were imported by a regular importer from a friend of mine in Florida who is a commercial developer. I had to pay quite a lot for them because of the middle man, it was worth it for a few lilies but it isn't something I can regularly do.
Can't help you with artificial sunlight but here is one of mine blooming in the natural stuff. Don't mind the tin foil on the caudex, it is to keep my cats from using it as a scratching post, something they like to do.
