One of several native Water-crowfoots, Common Water-crowfoot grows in still and slow-flowing water, in shallow ponds and small lakes. It bears 5-petalled white flowers (10-18mm across) on upright stems from April to August, the petals becoming golden yellow towards the centre of the flower. The nectaries are circular. There are deeply-lobed floating leaves and thread-like leaves which are submerged. It is a perennial, native plant which is uncommon and scattered mainly in the N East, East and S East of Ireland. It belongs to the Ranunculaceae or Buttercup family.
I first saw and photographed this plant in Coolcots, Co Wexford in May 2013, when visiting our friends, Mick O'Connor, Mary Foley and Brian O'Connor.
