Common Dandelion (Taraxacum)

Common Dandelion

Taraxacum officinale, the Common Dandelion, is a herbaceous perennial plant of the family Asteraceae. 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. As a nearly cosmopolitan weed, Dandelion is best known for its yellow flower heads, that turn into round balls of silver tufted fruits, that blow away on the wind.

Taraxacum officinale is a common colonizer after fires, both from wind blown seeds and seed germination from the seed bank. The seeds remain viable in the seed bank for many years, with one study showing germination after nine years. This species is a somewhat prolific seed producer, with 54 to 172 seeds produced per head, and a single plant can produce more than 5,000 seeds a year. It is estimated that more than 97,000,000 seeds/hectare could be produced yearly by a dense stand of dandelions. When released, the seeds can be spread by the wind up to several hundred meters from their source.

Common Dandelion originated from Eurasia.
