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.

Native south of our latitude, but widely planted in Michigan and locally established as a weed tree difficult to eradicate. Roadsides, fence-rows, fields, farmyards, and other disturbed areas; invading forests (beech-maple, aspen) and lightly forested dunes, river banks. First collected as long ago as 1862 in Washtenaw Co.
