Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, 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.

Erigeron hyssopifolius A. A. Reznicek

A boreal species of North America, ranging from New England to the Yukon, very local in Michigan. Locally frequent in rock crevices along the north shore of Lake Superior in Ontario, thence inland northward. Collected by O. A. Farwell as “rare” in Keweenaw Co. in 1890 (827, BLH); otherwise, known only from marly fens and associated open tamarack-cedar swamps in Mackinac Co.

This is an attractive, delicate-looking plant with white or pinkish rays, the color perhaps depending in part on the age of the flowers.
