Usually forested floodplains of major rivers, occasionally in swamp forests.
This is a more robust species than L. uniflorus, with dense and nearly spherical infructescences nearly or quite concealing the bracts and calyces. The nutlets are larger than in L. uniflorus. The leaves are sometimes reddish tinged.
This is widespread, though rare, in southern Michigan, with an outlying occurence along the Ontonagon River in the western Upper Peninsula. See Lycopus uniflorus for comments on hybrids.
