Has anyone else ever come across a Wild Strawberry flower looking quite like this? The serrated petal margin is certainly new to me! #wildflowerhour @bsbibotany.bsky.social

A flower of Wild Strawberry, with five white petals around a domed yellow mound covered with pistils which is surrounded by spoon-shaped golden stamens. This flower has unusually serrate petals.
