Identification hints

Orange coneflowers create a rosette of leaves in their first year of growth but generally do not produce a flowering stem until the second year. The flower blooms in the mid-spring through the fall and have a brown button-like disk surrounded by the yellow petal-like ray flowers.  After they bloom, the petals fall away and the small black fruits are produced.

Note that Rudbeckia hirta and Rudbeckia fulgidia share the common name of "Black-eyed Susan" -- an excellent lesson in why it is important to know and use scientific names.
