Also known as Yellow Clover, this is a low-growing, mat-forming, hairless annual which has between 5 and 20 yellow peaflowers in compact little flowerheads 8-9mm across. The trifoliate oval leaves are slightly notched, and not pointed, the terminal leaf being short-stalked. Lesser Trefoil flowers from May to October and can be found growing in dry, grassy places and wasteland. In autumn, the flowers turn brown and droop hiding the tiny straight pods. It is native plant belonging to the family Fabaceae.
I first identified this wildflower in 1978 at Kilcoole, Co Wicklow and photographed it at Ballyteigue, Co Wexford in 2008
