Coreopsis

This could be either Coreopsis basalis  or Coreopsis tinctoria. They’re both called Coreopsis and Goldenwave as a common name, and from looking at the photos and the description at the Wildflower Center’s database, there doesn’t seem to be much to tell them apart visually, if anything. This specimen is from my front yard, next to the Indian Blanket and Autumn Sage around the birdbath. Since it apparently likes moist soil, it is not surprising that this is the first year I’ve seen it in the front yard. A couple of years ago I spread some wildflower mixture seeds out in the back yard, and some Plains Coreopsis did come up, so perhaps this is a relic of that, reseeded by birds. At any rate, it is surely a Coreopsis. Maybe next year we’ll get some more.
