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.

Despite the name, this sunflower ranges less far west than many, and is in fact concentrated in Michigan and Wisconsin, less common southward. It is characteristic of our dry, very open, usually sandy savannas, such as jack pine and oak plains. It has also spread along railroads and in fields, and is found in dry prairies.
This is a very easily recognized species with the few leaves concentrated at the base of the plant, nearly naked stem, and colonial habit resulting from slender, shallow, pale rhizomes, which usually produce an abundance of leaf rosettes in a colony.
