Location

Common Dandelion originated from Eurasia. Now it is naturalized throughout North America, southern Africa, South America, New Zealand, Australia, and India. It occurs in all 50 states of the USA and most Canadian provinces

Physical Description
Taraxacum officinale grows from generally unbranched taproots and produces one to more than ten stems that are typically 5 to 40 cm tall but sometimes up to 70 cm tall. The stems can be tinted purplish, they are upright or lax, and produce flower heads that are held as tall or taller than the foliage. The foliage is upright growing or horizontally orientated, with leaves having narrowly winged petioles or they are unwinged. The stems can be glabrous or are sparsely covered with short hairs. The 5–45 cm long and 1–10 cm wide leaves are oblanceolate, oblong, or obovate in shape with the bases gradually narrowing to the petiole. The leaf margins are typically shallowly lobed to deeply lobed and often lacerate or toothed with sharp or dull teeth. The calyculi (the cup like bracts that hold the florets) is composed of 12 to 18 segments: each segment is reflexed and sometimes glaucous. The lanceolate shaped bractlets are in 2 series with the apices acuminate in shape. The 14 to 25 mm wide involucres are green to dark green or brownish green with the tips dark gray or purplish. The florets number 40 to over 100 per head, having corollas that are yellow or orange-yellow in color. The fruits, which are called cypselae, range in color from olive-green or olive-brown to straw-colored to grayish, they are oblanceoloid in shape and 2 to 3 mm long with slender beaks. The fruits have 4 to 12 ribs that have sharp edges. The silky pappi, which form the parachutes, are white to silver-white in color and around 6 mm wide. Plants typically have 24 or 40 pairs of chromosomes but some plants have 16 or 32 chromosomes. Plants have milky sap and the leaves are all basal, each flowering stem lacks bracts and has one single flower head. The yellow flower heads lack receptacle bracts and all the flowers, which are called florets, are ligulate and bisexual. The fruits are mostly produced by apomixis. It blooms from March until October

General Information

Dandelion root is a registered drug in Canada, sold principally as a diuretic
Dandelion leaves and roots have been used for hundreds of years to treat liver, gallbladder, kidney, and joint problems. In some traditions, dandelion is considered a blood purifier and is used for conditions as varied as eczema and cancer. As is the case today, dandelion leaves have also been used historically to treat water retention
Dandelion is commonly used as a food. The leaves are used in salads and teas, while the roots are sometimes used as a coffee substitute.
T. officinale is food for the caterpillars of several Lepidoptera (butterflies and moths), such as the tortrix moth Celypha rufana
Dandelions provide fair to good forage for livestock and wildlife, and are readily eaten because they are relatively succulent. Antelope, as well as sage and forest grouse, use it heavily. It is a species that inhabits disturbed areas. It is generally abundant on overgrazed rangelands, but can also occur on well-managed ranges.
The milky latex has been used as a mosquito repellent.
Yellow or green dye colours can be obtained from the flowers but little colour can be obtained from the roots of the plant
