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.

In addition to the wild plants, a garden cultivar known as “goldenglow,” R. laciniata cv. ‘Hortensia,’ derived from this species by conversion of all or most disk flowers to ray flowers, occasionally escapes. The dots on the map for Alpena, Ogemaw, and Schoolcraft Cos. and for the Manitou Islands represent only the cultivar, which is also documented as established in some of the counties from which the native plant has been collected.
