The thin-leaved sunflower (Helianthus decapetalus) looks similar to a thin-leaved coneflower (Rudbeckia triloba), expect the sunflower has a yellow central disk and the coneflower has a brown central disk. Another characteristic for distinguishing the two is leaf arrangement: opposite (sunflower) vs. alternate (coneflower).
