Familiar little wildflower of the woodlands and grassy hedge-banks, this plant is quite similar to Early Dog-violet and is easily confused. The unscented, blue-violet flower is always solitary on the stem, and is open with five petals, the lower of which has a stout, blunt, pale, curved spur which is notched at the tip. The mouth of the flower is absolutely wonderful to view through a hand-lens or magnifying glass. It has a pattern of deep purple lines which run into the throat over a paler violet patch, becoming white. The upper petals have a fringe which is over the opening. The dark-green, heart-shaped leaves are on long, slender stalks. This native plant which blooms from April until June is a larval foodplant of the Dark Green Fritillary. It belongs to the family Violaceae.
I first identified this flower in Killiney, Co Dublin in 1977 and photographed it in the Burren in 1999.
