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.

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

This Old World species is widely cultivated, and becomes weedy in lawns and vacant places in gardens, spreading even to forests. First collected in 1918 in Washtenaw Co., and doubtless much more widespread than indicated by the map.

The flowers are blue or white, and are often very fragrant. There are many horticultural forms, including double-flowered ones.
