Black-Eyed Susan
Rudbeckia hirta (Asteraceae)
A stiff, upright annual or shortlived perennial native to the eastern United States, but has become endemic throughout North America. The Black-Eyed Susan is probably the most common of all American wildflowers. The characteristic brown, domed center is surrounded by bright yellow ray florets. Thrives in most soils in full sun. A true sunshine worshiper that forgives neglect.

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 are a pioneer plant. That means they are one of the first plants to grow in a new field. For instance, if a fire burns down part of a forest, this plant will be one of the first to start growing.

Other plants that often grow near Black-eyed Susans include: Red Maple, Eastern White Pine, Eastern Redcedar, White Oak, Black Oak, American Beech, Silver Maple, American Elm, Virginia Pine, Loblolly Pine, Goldenrod, sedges, and Bracken Fern.

Snails, slugs, and aphids eat the leaves of this plant. Rabbits and deer eat the entire plant.

Some species of fungi grow on the roots of Black-eyed Susan. The fungi pull nutrients from the roots and, at the same time, pass nutrients to the plant from the soil.
