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.

Cercis canadensis flowers J. Creager flowers

Rich forests, usually along rivers and streams. A handsome flowering small tree reaching the northern edge of its range in southern Michigan, where it brightens moist forests locally in early spring.

Widely cultivated as an ornamental,  the Genesee and Mecosta Co. occurrences are certainly spread from cultivation, as are likely a few others from fields and forests near cities in parts of there state where there are also native occurrences.

Flowers may arise from older branches or even the trunk (cauliflory), a feature usually associated with tropical trees. See also Gleditsia.
