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.

Fields, roadsides, gravel pits, and other disturbed ground; invading shores, dunes, open forests, rocky openings, and moist habitats. One of the most familiar of all our thoroughly naturalized weeds, originally escaped from agricultural use. Collected in St. Joseph Co., in 1838 by the First Survey.
A variable species in stature, pubescence, and color of flowers. The last range from deep reddish purple to rarely white. The heads are the largest of any of our clovers, sometimes as broad as 3 cm, and ± spherical; in T. arvense and T. incarnatum they are ± cylindrical.
