Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net 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.

Native in southern Michigan and Menominee Co. in or near prairie remnants (including roadsides and fencerows), at margins of swamps, and in dry open ground. Most northern occurrences represent garden escapes or other waifs along roadsides or in rocky fields.
Specimens of Rudbeckia laciniata with drooping rays might be mistaken for this species, but differ in the essentially glabrous stems and peduncles and the greenish to brownish disk. Other Rudbeckia species with purplish disk and pubescent stem may have to be checked carefully for absence of chaff at the base of the ray flowers if they are puzzling; see also note under Rudbeckia.
