Buttercup, Creeping, Buttercup, Meadow,

A perennial of dry grassland, sandhills and lime-rich soil, this is a hairy plant without runners which is the case in Creeping Buttercup.  Reaching to about 50cm high, it has 5-petalled yellow flowers (20-30mm across) which differ from other Buttercups growing in Ireland by having the five sepals down-turned towards the stem. The flowers bloom on furrowed stalks from March to July.  The leaves are divided into three leaflets, the centre leaflet being long-stalked.  The stem of this plant is swollen – or bulbous -  at the base, and this swelling or corm enables the plant to survive throughout the winter by storing food.This is a native wildflower and it belongs to the family Ranunculaceae

I first identified this plant growing at the Cull, Kilmore Quay, Co Wexford in 2007 and I photographed it there in 2009.
