Rudbeckia named after Olof Rudbeck the elder (1630 - 1702) and the younger (1660 - 1740). Subtomentosa is from the Latin for "somewhat hairy".

Similar to R. hirta but with a somewhat less hairy stem; this plant's stem would more aptly be described as downy. Grows from 1 to 3 feet tall and prefers damp praireis and riverbanks. Orange-yellow flowers bloom from August through September.
