Common Fleabane is not easily confused with other wild plants on this web site.


This is a perennial which is commonly found in damp places and hedgerows throughout the country and flowers from July to September.  It is a stiff, downy plant, sometimes growing to 1m high which has clusters of yellow, daisy-like flowers on branched stems.  Each flower (15-30mm across) is comprised of numerous radiating ray florets and a centre of tubular disc florets.  The leaves are heart-shaped, wavy edged and they clasp the upright stems, the lower ones withering by the time the plant flowers.  This is a native plant which belongs to the family Asteraceae. 

My first record of this plant is from 1979 when I identified it growing at Killoughter, Co Wicklow.  The photographs were taken at Athy, Co Kildare in 2003.
