This is one of our larger (taller and larger flowers) Coreopsis species. Useful as a colorful wildflower along the edge of a wetland. Often overlooked as sunflowers are blooming at the same time. But if the site is appropriate, worthwhile.

The range of this species includes much of eastern North America up into southern Canada.  Its occurrence in Florida is sparse with appropriate substrate likely being the primary determining factor. Treasure if you have it. Good for rock gardens and shade gardens as an understory plant.
