Disturbed, moist ground, especially along shores of lakes, ponds and streams. Introduced from Europe and first collected in 1896 in St. Clair Co.
Plants resemble M. canadensis but differ in having smaller bracts toward the summit of the stem. Often, but not always, the calyx is glabrous. This is a hybrid derived from M. arvensis and M. spicata and is notoriously variable.
