This is a distinctive member of the Violaceae family in that it is stemless. The flowers and rosettes of leaves all arise directly from creeping underground stolons or runners. The five-petalled, pale-lilac flowers (10-15 mm across) have dark veins and a blunt, pale spur, the petals being rounded. There is no scent from these flowers. The hairless, kidney or heart-shaped leaves have long stalks and oval-shaped stipules at their bases. Blooming from April to July, this is a perennial plant. It grows to 15 cm high and is found throughout Ireland in acid bogs, marshy ground and damp woodland. Marsh Violet is a native plant.
I first recorded this plant on the Ridge of Capard in the Slieve Bloom mountains, County Laois in April, 2011.
