Hi Kevin. I somewhat grasp what you are saying now. I have been doing alot of reading up on this. I also have a variegated Echeveria called rainbow that I have added a picture of. I believe this to be a variegated form of Perle Von Nuremberg. Would Laszlo's variegated tectorum work in that experiment? I have three rosettes of it that I acquired this year. They haven't rooted fully yet with the summer heat here but they are looking good and when the weather cools they should be just fine.
