I Hate These Flowers

They are so big that the blossoms weigh down the stems and the flowers droop to the ground. It makes no sense biologically since these are the flowers that the bees love to be around and bees can fly. They are very fragile so if you cut them and take them into the house, the petals start falling off after only a day or so. No matter how much I try to pull them out by their roots every fall, they make their way back into my flower bed every damn year.
