Procumbent Yellow-sorrel is, as its name might suggest, a prostrate little plant which creeps across lawns and garden soil on slender, rooting stems and is now an extremely persistent garden weed. However, it is pretty with 6-10mm bright yellow flowers, usually 5 petalled and trifoliate leaves which have 3 heart-shaped lobes, slightly larger than the flowers. It is a garden escape which grows abundantly over dry, bare ground. A perennial, it is mainly confined to the South-East of Ireland. It belongs to the Wood-sorrel family.
I first saw this little plant in Ballyvalloo, Co Wexford in 2012 when I also photographed it.
