Physostegia virginiana A. A. Reznicek

Swamps, shores, river floodplain forests, wet thickets, moist open ground; also roadsides, ditches, near habitations, and other sites where probably escaped from cultivation. Specimens from Alpena, Grand Traverse, and Luce Cos. were surely escaped from cultivation, and some of the others, especially northern ones, are apparently of similar origin. The species appears indigenous north at least to the Grand, Pine, and Au Sable Rivers in the Lower Peninsula and the Menominee River in the Upper Peninsula.

All native Michigan specimens are subsp. virginiana. Cultivated variants of this species may include some results of hybridization.
