Celery-leaved Buttercup is not easily confused with other wild plants on this web site.

Easily overlooked, this little yellow-green annual wildflower is found growing in marshes, ditches and stagnant water.  Its little 5-10mm pale yellow flowers appear at the top of stout, ridged stems from May to September.  These are followed in autumn by fruits in conical, elongated heads containing hundreds of little seeds.  The leaves are celery-like, deeply lobed and shiny.  This plant is a native and belongs to the family Ranunculaceae.

I first found this plant near Shanganagh, Co Dublin in 1977 and photographed it at Blackditch Nature Reserve, Co Wicklow in 2005 and Tacumshane, Co Wexford in 2008.

'Sceleratus' translates as 'vicious' as the sap in this plant can cause great discomfort and blistering to human skin.  It can also be extremely toxic to livestock.
