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 sibirica B. S. Walters

A favorite cultivated Iris from Eurasia, established in moist, sunny roadsides, meadows, and shores. First collected by D. Henson in 1996 in Schoolcraft Co.

Older fruiting material oIris versicolor and I. virginica may appear to have a small hollow in the stem, but unlike these two species, I. sibirica has smooth outer spathe bracts. Flowers are typically blue, but white forms are also common, and other color combinations are present in some cultivars.
