About
From mid-summer into early autumn produces sprays of daisy flowers with yellow centres and pale purple or pink petals, though there are forms with no petals. Found all around the coast of the British Isles, this native aster is a biennial or short-lived perennial with narrowly oval, rather fleshy leaves on upright stems up to 1m tall. Fluffy, silvery seedheads follow in autumn. A good late nectar source for butterflies.
