Hope you can save your balloon flowers they are a lovely addition to the garden and bloom a long time if you remove spent blooms. I have the single and double in the blue color in my garden once you get them established they come back year after year. Here in the north they are late to emerge in the spring so a person needs to keep in mind where they are planted. I know some people have trouble getting them started but they are so worth the effort for the beauty they add to the garden. I bet mine have been in the garden at least 15 years.
