Native to southern Europe, northern Africa, and the Near East, occasionally escaped from cultivation. First collected in 1890 in Cheboygan Co.
The large, auriculate, scarcely lobed leaves are spiny-margined, and the strikingly large phyllaries are spine-tipped besides having spiny margins on the expanded bases.
