Platycodon (Chinese bellflower)

The flower that is on the right looks strange, doesn't it?
Usual platycodon have five-petalled flowers but it has four-petalled flower.
Every flower that is produced on this stem has four petals. I don't know why, but I'm so interested in it.
In Japanese flower calender and novels, this flower is one of the most typical autumn flowers. But in Yokohama, Chinese bellflowers are in full bloom in mid summer.
