Grassleaf coneflower (Rudbeckia graminifolia) by Julie Tew. Click on terms for botanical definitions. View post as a PDF.
Grassleaf coneflower is a Florida endemic perennial wildflower. Its solitary blooms are distinctly different than most Florida Rudbeckia species in that they have short, brick-red ray florets and large conelike disk florets. Comparatively, it is a small bloom among Rudbeckias. Its leaves are small, narrow and grasslike (hence the common name).
Grassleaf coneflower typically flowers in summer and occurs naturally savannas and along moist roadsides.
