Thank you, Daisy, for your fine photo of a seedling. In answer to Deb, they show themselves the first or second spring, I think. I usually wait until the next year when they bloom to move them if they are in the way. When they show their colour and type - simple, or Papageno-like, I find a good spot for them or pot them up for the Garden Club plant sale, with a label as to their colour.
Today a new seedling opened that took me by surprise. It resembles the very frilly pale mauve that Leftwood says is similar to the original Papageno. Thank you, Rick for that information.
Another lovely seedling that is at least two or three years old, wanted to be shown as well.
This plant looks better if you click on it, and then it can spread itself out a bit. I didn't realize that could be done until I tried it on my first picture way above. Then you could see all 5 plants that were seedlings of the original one by the plant tag.
Bluepoppy, I hope you've been able to get some plants or seeds so that you can get some happy interbreeding going on!
Thanks for this opportunity to share.
