A wildflower of dry grassland and sandy soil, this member of the well-loved Pansy family is a perennial plant with long-stalked yellow flowers (12-25mm across) which are larger than those of Viola arvensis or Field Pansy. There are two top petals, slightly overlapping, two wing-like side petals and a single larger petal. Clearly marked paths lead pollinating insects into the centre of the flower over which is a translucent fringe. Blooming from April to August, the petals are larger than the sepals and the flowers have short spurs. The leaves are toothed, oval with a heart-shaped base and the leaf-like stipules are pinnately lobed. This is a native plant, also known as Dune Pansy, and it belongs to the family Violaceae.
I first recorded this plant at Ballyteigue, Co Wexford in 2007 and I photographed it also.
