This is a tufted, hairy perennial with 5-petalled pink flowers (15-25mm) which grow in umbels on long stalks. The leaves are like those of Wood Sorrel, trifoliate, each heart-shaped leaflet marked with little orange or brown spots. It flowers from May to September, is an introduction and belongs to the family Oxalidaceae.
I first knew this plant as a garden plant but found it growing as a 'garden escape' in Ringsend, Co Dublin and also at Tacumshin, Co Wexford, both in 2008. It was photographed at Ringsend.
