They have thick, edible, black rootstocks and short rhizomes. Erect hairy stems carry linear-lance shaped to ovate, smooth or toothed edged, or deeply pinnatifid, bristly, dark green leaves. It bears solitary, daisy like, purple, red, pink, or white flowers, with pointed stiff scales on the undersides and prominent, ovoid, or cone shaped, brownish yellow to orange centers, are held in terminally on thick, sometimes sparsely branched stems. Grow in a herbaceous border or open woodland.
Grow in deep, well drained, humus rich soil in full sun, although they will tolerate some shade. Cut back stems as the blooms fade to encourage further flower production and to prevent excessive self seeding. Divide every 3 or 4 years in spring.
