The leaves are very spiny, lobed, 10–30 cm long and 2–5 cm broad (smaller on the upper part of the flower stem). The inflorescence is 3–4 cm diameter, purple, with numerous disc florets but no ray florets. The achenes are 4–5 mm long, with a downy pappus which assists in wind dispersal. It is monocarpic, growing as a low rosette of leaves for a number of years, then sending up the tall flowering stem in spring, with the plant dying after seed maturation.[5]
Edible thistle is used by Native Americans for its edible roots and young shoots. The roots are sweet, but contain inulin, which gives some people digestive problems.[6]
