This plant may be short or quite tall, forming low clumps or towering to heights approaching 3 meters. The leaves are dull gray-green to bright white due to a coating of hairs, and the most basal ones on large plants may be nearly half a meter in length. The petioles are winged and spiny and the leaves are toothed or edged with triangular lobes. In Botany, the petiole is the small stalk attaching the Leaf blade to the stem. The inflorescence at the top of the whitish stem holds one to several flower heads. An inflorescence is a group or cluster of Flowers arranged on a stem that is composed of a main Branch or a complicated arrangement of branches Each head is somewhat spherical, covered in large phyllaries with very long, spreading spines which are laced, often quite heavily, in fibers resembling cobwebs.
