Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

Rudbeckia fulgida Aiton
Coefficient of Conservatism: 9
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb

Fens, sedge meadows, calcareous springy banks, riverside swamps, meadows, and other wet (sometimes rocky) ground.

Our plants are all var. sullivantii (C. L. Boynton & Beadle) Cronquist, sometimes recognized as Rudbeckia sullivantii. The commonly grown cultivar ‘Goldsturm’ is derived from this species, but almost all of our collections are wild plants from native wetland settings.
