In many ways similar to White Clover (pictured together below), this hairless perennial is found in verges, waste ground and cultivated ground. Its little upright heads of flowers start out white or pale purple but turn pink or brown as they age. The 2cm flowerheads are stalked and bloom from June to October. The leaves are trifoliate and without markings. This is an introduced plant belonging to the family Fabaceae.
I found this wildflower by Tacumshane Lake in Co Wexford in 2008 where I photographed it.
