Habitat: Dandelion can be found in the temperate regions of Europe, Asia and North America. Hundreds of species of this hardy and beneficial herb are found throughout the Northern Hemisphere.

Some botanists believe that the plant is circumpolar; that is, native to all the temperate regions of the northern hemisphere.

Others botanists classify the dandelion as a species introduced to North America from Eurasia. It is found growing wild in meadows, pastures, waste grounds, sand, gravel, rocks, and even cracks in concrete.

Most commercial dandelion is cultivated in Bulgaria, Hungary, Poland, Romania and the United Kingdom.

Plant Description: Dandelion is a hardy, variable perennial that is closely related to chicory (Cichorium intybus) that can reach a height of nearly 12 inches.

The roots are fleshy and brittle roots are filled with a white milky substance that is bitter and slightly odorous. The dark brown roots may reach into the soil for a foot or more.

The shiny, hairless leaves are irregularly dentate or pinnate, either oblong or spatulate. The leaves grow in a rosette from the milky taproot. The grooved leaves funnel rainfall down to the roots.

The yellow flowers grow singly on a straight stem that is leafless, hollow, smooth and pale green; it may be tinged with mauve. The flowers are light-sensitive, opening in the morning and closing in the evening or in the event of cloudy weather.

The familiar puff-ball that succeeds the flower is a globular cluster of achenes, each of which is fitted with a parachute-like tuft that easily floats on the breeze in order to distribute the seeds.

Plant Parts Used: Leaves and root.
