Article History

thistle, weedy species of Cirsium, Carduus, Echinops, Sonchus, and other plant genera of the family Asteraceae. The word thistle most often refers to prickly leaved species of Carduus and Cirsium, which have dense heads of small, usually pink or purple flowers. Plants of the genus Carduus, sometimes called plumeless thistles, have spiny stems and flower heads without ray flowers. Canadian thistle (Cirsium arvense) is a troublesome weed in agricultural areas of North America, and more than 10 species of sow thistle (Sonchus) are widespread throughout Europe. Some species of globe thistle (Echinops) are cultivated as ornamentals. The thistle is the national emblem of Scotland.
