Black-Eyed Susan

The Black-Eyed Susan (Rudbeckia hirta) has been the official Maryland flower since 1918. Black-Eyed Susans are perennial daisies or coneflowers, members of the sunflower family (Asteraceae). The flower heads measure 2 to 3 inches in diameter with yellow rays circling a dark-brown, spherical center. Commonly found in fields and on roadsides, they bloom between May and August, reaching 2 to 3 feet in height. They are native to the United States, east of the Rocky Mountains.

Black-Eyed Susans survive in most soils in full sun. They are a great choice for the summer heat because they can be neglected. However, it is important to keep in mind that they are competitive and can overtake other plants and become invasive.
