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.

The flowers are usually some shade of orange, but may be clear yellow or bicolored. As our only milkless milkweed, with alternate leaves besides, this is a readily recognized plant. It develops a massive, almost woody tuberous root, from which numerous ± lax stems may arise. The flowers are indeed very attractive to butterflies and other insects.
