The plant reaches 1-2 m in height with sparsely prickly, ridged stems. Basal leaves are large and pinnately lobed; stem leaves are opposite, lanceolate to oblong, with toothed margins and prickly midribs. Dense globose flower heads 2-3 cm across, ringed with stiff involucral bracts, bear small white to pale purple tubular florets. The thick, fleshy taproots are harvested in autumn.
