Rudbeckia triloba L.
Common Name: THREE-LOBED CONEFLOWER
Coefficient of Conservatism: 5
Coefficient of Wetness: 3
Wetness Index: FACU
Physiognomy: Nt B-Forb

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.

The leaves are often all unlobed. Even when lobed leaves are present, the plant looks quite different from R. subtomentosa. Besides the characters noted in the key, the pubescence on stems and leaves consists of scattered long hairs, while in R. subtomentosa it consists of short dense hairs.
