That's cool! I had two surprises this year. I noticed that half of my clump of Casper's Shadow is very different. Must have been a seed that grew and finally decided to bloom this year. The same thing is true of Gizmo the Gremlin, had two blooms open that are different then the parent.
Casper on the right, impostor on the left.
Gizmo is the darker ones on the bottom of the picture, the impostors are the lighter colored ones at the top of the picture.
Now I have to make sure I get them moved out of there.
