Why does everybody hate dandelions? We loved them when we were children! I suspect many of us still do. I remember blowing the wispy seed heads, and my delight in watching them float away on the wind. I also remember mortified adults yelling, "Don't do that!" - terrified of finding their neatly manicured lawns filled with dandelions.
I grew them in my garden once, on purpose. My doctor told me that they have more iron than spinach, which is great for treating anemia.
