I had a surprise this morning. I have previously posted my sibling seedlings of my cross with Cosmopolitan x Clouds of Kisses. This morning, sibling #5 bloomed a full double. It had some extra petals on its second bloom, and the first bloom was a single.
I did some research and here is what I found. Cosmopolitan, pod parent, has 13 child plants, two of which are doubles. Clouds of Kisses, the pollen parent, only has one child, a single. Then I looked at the pod parent of Clouds of Kisses, Janice Brown, and she has several child plants that are doubles.
