Senecio aquaticus - Marsh Ragwort - (Asteraceae)

Found mainly in marshes, in ditches and on damp, shaded riverbanks, this member of the ragwort family often has rather an unkempt appearance. Marsh ragwort blooms in June, July and August. The flowers are larger and much less densely clustered than those of common ragwort. A further distinguishing feature is the rounded ends to the leaves.
