Share on

Common Name: Biennial Black-eyed Susan

Germination Code:  C(30)

Native Region: Middle and East Tennessee, lightly in West Tennessee

May be annual, biennial or short-lived perennial.  Plant can become a pest by re-seeding but does put on a striking floral display.  Not as attractive as many of the other rudbeckias. Native to prairies, plains, meadows, pastures, savannahs, and woodland edges. Attracts birds and butterflies.
