The basal leaves are usually lanceolate or elliptical and petiolated.[2] The flower heads are pink to purple, spherical and very large (about 6–10 centimetres (2.4–3.9 in) in diameter).[2] The bracts are brownish and membranous. The flowering period extends from June to August. The flowers are hermaphroditic and are pollinated by insects. The fruits are brown achenes.
