In not too dry forests, at the bottom of a valley or on a shaded slope under the trees, you can find those little white flowers very early in the year among the Yvy leaves.
They look like wild strawberry flowers but they bear no fruit, as indicates their name: Barren Strawberry (Potentilla sterilis).
Also the leaves look like strawberry leaves. Maybe a bit smaller and with some silken hairs.
Even if you don't make strawberries, isn't it enough to have nice flowers?
