Two years ago a friend gave me some balloon flower cuttings to plant.
After planting they developed nicely and produced nice blue flowers.
This year the flowers are white.
Why the change in color?
How do I keep them blue?

I've never read why they do it but balloon flowers can indeed from one
summer to the next turn spontaneously from blue to white, or to white
striped, sometimes even to doubles. If you get a good oddity you can take
cuttings and get lots of them.

Would this maybe have any connection with the soil being alkaline or acidic?
