What plant is this
I noticed this year in a local field that this plant with a single pea like pink flower at the top of what I can only describe as a stem similar to that of a snakeshead fritillary. Can anyone tell me what it is please. the flower is about 1/4" across and the whole plant is very delicate and appears in a single patch of grass and other wild plants. The whole plant is about 12-14" high.
