Rudbeckia Triloba

Wet prairies and borders of floodplain forests; also in ± disturbed sites on shores and edges of marshy or swampy ground. The northernmost records, at least, and probably some others, may represent escapes from cultivation although the species has naturally weedy tendencies. Rudbeckia triloba is an herbaceous biennial or short-lived perennial with many common names including branched coneflower, thin-leaved.

Rudbeckia triloba^[1] (browneyed susan, brown-eyed susan, thin-leaved coneflower, three-leaved coneflower) is a species of flowering plant in the sunflower familynative to the United States. It is often seen in old fields or along roadsides. It is also cultivated as an ornamental.

It is a short-lived herbaceousperennial found in the Central and Eastern United States. Height is 2–3 ft (60–90 cm) with a spread of 1.0 to 1.5 ft (30 to 45 cm). The species requires full sun and moist soil. It is easy to grow. Spent flowers should be removed to encourage additional bloom, prevent any unwanted self-seeding, or both. This species usually has smaller flowerheads, more flowerheads per plant, and fewer ray flowers per flowerhead than Rudbeckia hirta. Rudbeckia triloba basal leaves are often trifoliate (three leaflets, sometimes each of the three also divided).
