After looking back at my records, I'm 99.99% sure that number 1 is the Platycodon X Fujishibori F1.
Number 2 looks like a Hanafubuki purebred and don't have a clue where number 3 came from - It's more yellow than my camera was able to pick up. It will be interesting to see if future blooms from the same plant come out that yellow.
