Name: Common Dandelion (Taraxacum officinale)
Order: Asterales Family: Asteraceae Tribe: Cichorieae Description: Taraxacum officinale grows from generally unbranched taproots and produces one to more than ten stems that are typically 5–40 cm (2.0–15.7 in) tall, but sometimes up to 70 cm (28 in) tall. The leaves are 5–45 cm (2.0–17.7 in) long and 1–10 cm (0.39–3.94 in) wide, and 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 cuplike bracts that hold the florets) are composed of 12 to 18 segments. Distribution: Taraxacum officinale is native to Europe and Asia, and was originally imported to America as a food crop. It is now naturalized throughout North America, southern Africa, South America, New Zealand, Australia, and India. It occurs in all 50 states of the US and most Canadian provinces. Habitat: 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. Fun fact: It is considered a noxious weed in some jurisdictions, and is considered to be a nuisance in residential and recreational lawns in North America. It is also an important weed in agriculture and causes significant economic damage because of its infestation in many crops worldwide.
