Field Scabious (Knautia arvensis), a member of the teasel family
These are the same wildflowers that you see in my previous post. I have not come across them anywhere else but in this dry, sunny location where they grow in profuse splendor. Each flower "button" is a dense cluster of small single flowers. On the day that I was here, the bees and butterflies were oblivious to onlookers as they went from flower to flower, busily collecting nectar.
