Balloon Flower Question
Last fall I had 2 potted Blue Balloon flower (Platycodon grandiflorus) seedlings that became bug infested. I set them outside and after several hard frosts I brought them into the greenhouse. One of the 2 came back up and is now blooming. You can view at the link shown below.
My question is if I set this plant outside before the winter is over can I cause it to go dormant, then plant it in the flower bed this spring and get it to bloom again this summer?
