I know they are not just flowers but do have beautifull blossums.
Blueberries absolutley love acidic soil. I live inmontana and have been trying to find a berry forum
I like to plant rasberries blueberries strawberries gooseberries currants grapes and well just any berry I can find I will try.
Unfortunatly our sometimes unpredicible weather makes it fustrating. (its snowed here in july before)
anyway if you haev ahard time with flowers try blueberries yummy
