The bracts supporting the flower are snowy white on the outer half, giving the whole head a white appearance. Disc flowers are rose-colored to dark wine, and there are no ray flowers. The flowers are funnel-shaped, 5-lobed, and numerous. Many-branched stems arise from a basal rosette of pale bluish, bipinnate leaves.
