Cirsium
Also called Thistles, Plume Thistles
Cirsium is a genus of perennial and biennial plume thistles in the daisy family, mostly native to Eurasia and northern Africa, with about 60 North American species. Grown mainly as hardy garden and wildlife plants, with spiny leaves and showy purple, pink, yellow or white flower heads.
Cirsium is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera (Carduus, Silybum and Onopordum) in having a seed with a pappus of feathered hairs on their achenes. The other genera have a pappus of simple unbranched hairs.
They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). The lectotype species of the genus is Cirsium heterophyllum (L.) Hill.
