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 viewpoint, and only accept a total of about 60 species.

The leaves are 5-25 cm long, simple and basal, entire or lobed, forming a rosette above the central taproot. As the leaves grow outward they push down the surrounding vegetation, such as grass in a lawn, which kills other plants by cutting off their access to sunlight. A bright yellow flower head, which is open in the daytime but closes at night, is borne singly on a hollow stem (scape) which rises 4-30 cm above the leaves and exudes a milky sap (latex) when broken. A rosette may produce several flowering stems at a time. The flower head is 2-5 cm in diameter and consists entirely of ray florets. The flower head matures into a spherical "clock" (also known as "wishies") containing many single-seeded fruits (achenes). Each achene is attached to a pappus of fine hairs, which enable wind-aided dispersal over long distances.

Dandelions are used as food plants by the larvae of some species of Lepidoptera (butterflies and moths). See List of Lepidoptera that feed on dandelions.

Away from their native regions, dandelions have become established in the Americas, Australia, and New Zealand, and are now common throughout all temperate regions.

  • Here one brings in those big 'ol guns.... a good scraping and dumping, followed by round-up!!! Wait a couple weeks, add a 1 in layer of top soil and maybe a few pounds of wild flower seed. Before long you shall see an abundance of color and a feast for the bees!!
