They're fairly close to the ground and seem to grow in clusters. At a glance they look white or very faintly pink, but up close they are indeed pink but also purple, the blossoms are about 3/4 of a centimeter wide and have 4-5 petals per flower. They don't seem to have leaves but the stems and buds are a vivid green.

Are these weeds or flowers and are they wild or do they need to be put on the lawn?
