And yet, just across the border, southern Michigan only has virginica,
no versicolor.
I've seen a double form of pseudacorus escaped around here, and have a
bearded iris (no flowers yet) I collected from state land in northern
Michigan far from obvious homes. This spring I found a clump of
siberica/sanguinea blooming at Ojibway Prairie Provincial Nature
Preserve in Ontario (see attached photos). Apparently controlled burns
are to its liking.
Curiously, my lacustris clumps set quite a lot of seed of their own
accord this spring. I wonder if, in the wild, they have good seed set
under certain weather conditions that happen only once every so many
years.
