This is an upright perennial which reaches about 70cm in height and which is found on heaths, coastal cliffs and in a wide variety of habitats. It has stiffly erect stems which bear large inflorescences of stalked yellow flowers. Each flower head (15-18mm across) has both disc and ray florets, the inner disc florets numbering up to 30, the outer ray florets numbering up to 12. The slightly tatty-looking flowers bloom from July to September. Its seeds are borne on a pappus. The oblong leaves are alternate and slightly toothed. This is a native plant belonging to the family Asteraceae.
I first recorded this plant growing on turf beside the sea at Rath, Caherdaniel, Co Kerry in 1977 and I photographed it in the Burren, Co Clare in 2006.
