A native of Europe and adjacent Asia and occasionally cultivated, this was first collected as an escape in Michigan in Ingham Co. in 2014 by P. Carrington, growing in a disturbed bottomland forest. Our escaped plants are bulblet-bearing and are the typical subsp. carinatum; plants cultivated for ornament usually produce flowers only, and have been recognized by some authors as subsp. pulchellum (G. Don) Bonnier & Layens. If a plant bearing only flowers were found as an escape, it would key here to A. rotundum, at least based on having cauline leaves, but would differ, among other features, in the anther filaments lacking appendages.
