The Persian scientist and philosopher Ibn Sīnā around 1000 CE wrote a book chapter on Taraxacum.Gerard of Cremona, in translating Arabic to Latin around 1170, spelled it tarasacon.A number of species of Taraxacum are seed-dispersed ruderals that rapidly colonize disturbed soil, especially the common dandelion (T.officinale), which has been introduced over much of the temperate world.
The inner bracts are erect until the seeds mature, then flex downward to allow the seeds to disperse.
When development is complete, the mature seeds are attached to white, fluffy “parachutes” which easily detach from the seed head, glide by wind, and disperse.
Many similar plants in the Asteraceae family with yellow flowers are sometimes known as false dandelions.
Like other members of the Asteraceae family, they have very small flowers collected together into a composite flower head. In part due to their abundance along with being a generalist species, dandelions are one of the most vital early spring nectar sources for a wide host of pollinators.
The species of Taraxacum are tap-rooted, perennial, herbaceous plants, native to temperate areas of the Northern Hemisphere.
