Tall Coreopsis (Coreopsis tripteris)

This tall plant holds small bright yellow flowers above the prairie grasses in late summer. In the fall the leaves of Tall Coreopsis turn from green to a burgandy red color, and the seeds smell slightly like dill! A lovely plant native to Illinois mesic-wet prairies, this plant adds interest to late summer natural areas.
