This is a trait that I think I have always been interestd in and now I see it showing up even in the seedlings that I have not been intentionally breeding for green such as my ruffled seedlings. I suppose it would be kind of neat if an all green flower showed up. Not all of these seedlings are what you might call the finished product, but the best or greenist will be kept for further improvement of flower shape etc. of this interesting trait.
