Ecology

An annual or possibly perennial herb, parasitic on Achillea millefolium. It typically occurs on dry, somewhat basic soils in cliff-top grassland and on roadsides and grassy banks, usually near the sea. More rarely, it occurs in disturbed artificial habitats. Flowers can reappear after decades of absence, suggesting that the seeds are long-lived or that plants can persist without flowering for many years. Lowland.
