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.

Iris germanica L.
Coefficient of Conservatism: *
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Ad P-Forb

The common garden Iris rarely (or one might say barely) escapes from cultivation, but can doubtless be found in more counties than those mapped. First collected in 1936 in Kalamazoo Co. Not all garden irises should be called I. germanica, and the name is not used here in a strict sense. Works on cultivated plants should be consulted by those desiring more understanding of this species.
