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.

A variable circumpolar species, rarely found, except on rocky shores and ridges, limestone pavements, and “mountain” summits.

Except for one collection from a disturbed roadside on Drummond Island, which is 4.5 dm tall, our plants are not over 2.5 dm tall and often are as short as 1 dm; C. pensylvanica is often taller.
