The common name Dandelion is given to members of the genus Taraxacum, a large genus of flowering plants in the family Asteraceae. In the Asteraceae (formerly Compositae) the "flowers" are morphologically a composite flower head consisting of many tiny flowers called florets. Dandelions are native to Europe and Asia and have been widely introduced elsewhere. Many Taraxacum species produce seeds asexually by apomixis, where the seeds are produced without pollination, resulting in offspring that are genetically identical to the parent plant.
Dandelions are tap-rooted biennial or perennial herbaceous plants, native to temperate areas of the Northern Hemisphere of the Old World. They are commonly known as weeds or ruderals. The genus is taxonomically very complex, with numerous macrospecies, and polyploidy is also common; over 250 apomictic microspecies have been recorded in the British Isles alone (Richards 1972). Some botanists take a much narrower view and only accept a total of about 60 species.
