The balloon flower plant I have Is on its third season of blooming. I’ve noticed though, that the blooms are a much lighter blu
e than they were last year. What is the reason for this? Is there anything I can do or add to the plant to make the color go back to what it was? As I said, this plant has come back for three years. I had another one about 10 feet away and it didn’t come back this year. I was wondering what the reason for that was too.

Your plant is likely a hybrid and the colors are reverting or showing traits of one or more of the parent plants.
Does that mean there’s nothing I can do to get the color more bright blue the way it was when I bought it? I have heard adding egg shells to hydrangeas can change their color, is there anything that I can add to my balloon flower?
