This small, low-growing plant is more often found growing on old walls and in bare, stony places. A hairy, sticky annual, it grows to about 15cm high and often has a reddish hue to its leaves and stalks. The white, 5-petalled flowers (4-6mm across) are borne in clusters on erect stalks, flowering from March to September. The leaves are pinnately divided into 3 or 5 lobes and are untoothed. It is a native plant and it belongs to the family Saxifragaceae.
I first found this little plant growing on a window-sill in the cathedral ruins at Cashel, Co Tipperary in 1977. I photographed it in Mullingar, Co Westmeath and Kilkenny town in 2009.
