Onopordum acanthium (cotton thistle, Scotch (or Scottish) thistle) is a flowering plant in the family Asteraceae. It is native to Europe and Western Asia from the Iberian Peninsula east to Kazakhstan, and north to central Scandinavia, and widely naturalised elsewhere,[1][2][3] with especially large populations present in the United States and Australia. It is a vigorous biennial plant with coarse, spiny leaves and conspicuous spiny-winged stems.[4]
It should not be confused with Cirsium vulgare (spear thistle), which is also known as Scotch or Scottish thistle and is the national flower of Scotland.[citation needed] Spear thistle is native to Britain, while cotton thistle is non-native.
