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 understand that balloon flower have two different colors: deep blue
and white.
so isn't that you had both when you got the cuttings?
There seems to be a slight difference in size between these two.
ive never heard of the story which says that they change colors like
hydrangea.
