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.

Dyssodia

Tagetes erecta L. (incl. T. patula L.), Marigold, was collected by Douglass Houghton at Sault Ste. Marie, Chippewa Co., Oct. 1, 1831! – but without any indication of whether planted or wild. It resembles a large Dyssodia, is similarly glandular and strong smelling, and would run to here in the key. Tagetes, however, has much larger heads with longer, more conspicuous rays and involucral bracts connate for at least 1/3 of their length (as opposed to ± free).  Though not confirmed as a wild plant in Michigan, T. erecta has been collected as an escape in adjacent Lambton Co., Ontario.
