- The dandelion is often treated as a scourge of the finely manicured lawn that has become a symbol of suburban America. The plant has been used beneficially for thousands of years and was introduced to the Americas by early colonists. But today it mostly gets treated to a dose of herbicides. The flower matures into this spherical clock containing many single-seeded fruits each attached to a pappus of fine hairs, which enable its wind-aided dispersal.
