Indeed, Dandelions are beautiful when blooming, but less so before the blooms where they appear as alien hydras with many heads and flailing tentacles.
The flower stalks grow unbelievably fast too. I have been trying to rein in dandelions on my lawn this year, and thought I could control them by just snipping off the flower heads. Soon, I realized this would take an hour of labor a day that I didn't have to spend on lawn maintenance.
