Elena, I agree that it might do better elsewhere, but having that pop of color is worth the loss of a few blooms.
My 'Outrageous' is in almost full sun and on really hot, sunny days the edges turn white and the nice saturation of color is gone like in this picture. That is 'Lavender Blue Baby' at the bottom right and the color is almost completely washed out. I haven't moved my Outrageous for over 12 years, but have given away several starts.
