Sub-category: Aster family
A tall biennial or short-lived monocarpic thistle, forming a rosette of leaves and a taproot up to 70 cm long in the first year, and a flowering stem 1 to 1.5 m tall in the second (rarely third or fourth) year. The stem is winged, with numerous longitudinal spine-tipped wings along its full length. The leaves are stoutly spined, grey-green, deeply lobed; the basal leaves up to 15 to 25 cm long, with smaller leaves on the upper part of the flower stem; the leaf lobes are spear-shaped (from which the English name derives). The inflorescence is 2.5 to 5 cm diameter, pink-purple, with all the florets of similar form (no division into disc and ray florets).
Found in fields, meadows, along forest edges, roadsides, and waste areas.
