Taraxacum officinale, the common dandelion [simply “dandelion”], is a flowering herbaceous perennial plant of the family Asteraceae [Compositae]. It can be found growing in temperate regions of the world, in lawns, on roadsides, on disturbed banks and shores of water ways, and other areas with moist soils.
Taraxacum officinale is considered a weed, especially in lawns and along roadsides, but it is sometimes used as a medical herb and in food preparation. Common dandelion is well known for its yellow flower heads that turn into round balls of silver tufted fruits that disperse in the wind called “blowballs” or “clocks” containing many single-seeded fruits called achenes. Each achene is attached to a pappus of fine hairs, which enable wind-aided dispersal over long distances.
