northern blue flag, Iris versicolor

Northern and southern blue flags? I hope you can tell them apart better than I! The colored spots on the sepals (the three largest colored parts that stick out sideways) are allegedly more yellow on the southern flowers. The little bumps in that area are shorter on the northern ones. The bracts have a little more color and slightly different texture with the southern version. For me, these have always seemed like very subjective traits, hard to evaluate without side-by-side flowers, and not easy even if you do have both at once, which is very unlikely. But the one you see here is a northern blue flag because it was far enough north that there are no southern ones around. Northern blue flags can be seen, if not necessarily identified, in CT, DE, ID, IL, KY, MA, MD, ME, MI, MN, NH, NJ, NY, OH, PA, RI, VA, VT, WI, LB, NB, MB, NB, NF, NS, ON, PE, QC, and on SPM. Flora of North America does not include DE, ID, IL, and KY in the range. Chippewa Co MI, 6/20/21. Iris family, Iridaceae.
