These are the flower heads. They turn bronze in the fall, and yellow in winter. Pretty stuff — can be dried. Note there is a spring flower that’s also called wild oats (sessile bellwort). Native.

Thanks to Alert Flowerophile Donna for noticing a flock of these little lilies at Wilson Mountain. Sessile means sitting or resting on the surface — these have sessile leaves, which means the leaf comes directly out of the main stem, but the leaf itself has no stem of its own. From the Lily family. Native to this region.
