Rudbeckia triloba [1] (browneyed Susan, brown-eyed Susan, thin-leaved coneflower, three-leaved coneflower) is a plant native to the United States. It is sometimes grown in gardens, but it is usually seen in old fields or along roadsides.

Herbaceous biennial to weak perennial. Native to central-eastern United States. Height is 2–3 feet with a spread of 1 to 1.5 feet. Needs full sun and medium water. Easy to grow. Deadhead spent flowers to encourage additional bloom and/or to prevent any unwanted self-seeding. This plant is in part distinguished from black-eyed Susan by having a more profuse bloom of smaller flowers that usually have fewer rays per flowerhead. The basal leaves are often trifoliate (three leaflets, sometimes each of the three also divided.)
