Along the roadsides and laneways of rural Ireland, from April to June, this perennial scrambles and straggles its way over other vegetation and banks, putting up a great display. Its snow-white flowers, 15-20mm across, have 5 deeply cleft petals and are borne in cymes of 7-11 on rough-edged stems from April to June. The sepals are only half as long as the petals. The leaves are narrow, unstalked and grass like. This is a native plant and belongs to the family Caryophyllaceae.
I first identified this flower in Roundwood, Co Wicklow in 1976 and photographed it near Ballymitty, Co Wexford in 2005.
