Wildflower garden, meadow.

Further north, this can be a moderately large tree. Not typically grown but worth retaining if present as an understory tree.

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.

Keep it if you have it.

Makes a good specimen tree or a cluster of in wet areas along margins of lakes and ponds. This tree is columnar in form and can make a formal-looking plant near an entryway.

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.
