Barren Strawberry, Potentilla sterilis, is a non-fruiting cousin and easliy mistaken for Wild Strawberry. It does however have a few distinguishing features, which make it easy to identify. The petals are more widely spaced and have a dent rather than a point. The leaves are coarser with a blue green colour and are generally smaller. The whole plant is more stout and hairy.
