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.

Zizania aquatica L.
Coefficient of Conservatism: 9
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt A-Grass
Status: T

Rivers, streams, lakes, and ponds, seldom in water much over 6 dm deep. Wild-rice grows best in shallow (but not stagnant) water where there is at least a slight current over a muddy, mucky, or silty bottom, and where there is little competition from other plants.

This is a very large grass (up to several m in height), and being more southern in range, has been more seriously affected in Michigan by drainage and water quality degradation in more populated areas.
