Taraxacum polium

Taraxacum polium, commonly called the Gotland dandelion is a perennial species of dandelion in the family Asteraceae, native to southeastern Sweden. It is primarily found on the island of Gotland, where it inhabits moist grasslands, meadows, woodland margins, and roadsides. The species was first described in 1910 by Swedish botanist Gustav Adolf Hugo Dahlstedt in Arkiv för Botanik, based on material collected from a railway embankment in Endre parish. Although morphologically similar to related species such as Taraxacum spectabile and T. nordstedtii, T. polium is distinguished by its bluish-grey, densely hairy foliage; narrow, reflexed leaf lobes; small, convex capitula; and short, broadly ovate involucral bracts. It has also been introduced to British Columbia, Canada, where it occurs as a weed in urban and roadside habitats....read more on Wikipedia.
