R. hirta is found throughout the Tallgrass region and is prevalent under a variety of conditions. It generally prefers drier areas. A perennial growing to 3 feet tall, it has bright orange-yellow flowers that bloom from June to September. The stem is hairy and without branches below the flower heads.
Rudbeckia named after Olof Rudbeck the elder (1630 - 1702) and the younger (1660 - 1740). Hirta is from the Latin word for "hairy".
Black-eyed Susan was used extensively by early settlers as a stimulant and a diuretic. They brewed a tea from the dried leaves and felt it acted as a stimulant for the kidneys. The Potawatomi made a tea from the root to relieve suffering from colds.
