Pronunciation guide: (phonetic spelling) rood-BEK-ee-uh (or rood-BEK-e-a or rud-BEK-ee-a) try-LO-buh Flower name (common): Brown-Eyed Susan Family name (common): Aster Family name (scientific): Asteraceae Scientific name origin: Genus: Named by Linnaeus to honor the botanists Olof Rudbeck the Younger (1660–1740), and his father Olof Rudbeck the Elder (1630–1702). Specific epithet: Originally from the Greek, meaning three-lobed. Refers to some of the lower leaves having three lobes. Common name origin: Possibly from the brownish-purple color of the disc florets and the similarity of the plant to Rudbeckia hirta, which is commonly called black-eyed Susan. Who Susan refers to is unknown. Flower description: Size: 1.0 to 2.0 inches (2.5 to 5.1 cm) Petal count: 8 to 15 ray florets, disc florets 150 to 300+. Color: yellow Other: flower arrangement, Panicle Plant description: Size: 12 to 60 inches (30 to 152 cm) Stem hairy: Other: Leaf description: attachment is alternate, type is simple and lobed Size: Color: Hairy: Other: Shape: leaf, ovate to subcordate or elliptic (not lobed) (FNA), lanceolate to ovate (IL), a few of the lower leaves are divided into three lobes. Origin (native, introduced, invasive): Native Status (common, uncommon, threatened, rare): Uncommon Bloom time (typical): July to October Cycle (annual, biennial, perennial): Biennial/Perennial Habitat: Woods, prairies, meadows, savannas, thickets, pastures, disturbed areas, roadsides, sun or semi-shade, moist to wet. Fruit: Seed: Importance to wildlife: Similar species (if any): Rudbeckia hirta (Black-Eyed Susan) has a resemblance and the flowers of Rudbeckia laciniata (Cut-leaf Coneflower) can also look similar to Rudbeckia triloba. Rudbeckia laciniata (Cut-leaf Coneflower) can be distinguished by its deeply lobed or divided leaves. Rudbeckia triloba can be differiated from Rudbeckia hirta by its more extensive inflorescences and its tri-lobed lower leaves. Sometimes the the latter can be few in number, as these leaves fall off during the season. The upper leaves of Rudbeckia triloba are commonly not lobed.
