A European species, locally spread from cultivation into wet lake shores, river edges, marshes, and ditches; sometimes forming dense stands. First collected in Wayne Co. in 1932.
This is a robust species, larger than our native Iris species, and forming dense colonies. Striking when in flower, fruiting plants can be identified as noted in the key. The seeds are round, as often the case in I. virginica, but more smooth, lacking the conspicuously pitted surface typical of I. virginica.
