Considered to be a Eurasian native. Reported as early as the First Survey, and first collected in 1842 (locality unspecified), now in disturbed ground everywhere: roadsides, railroads, parking lots, gravel pits, farmyards, filled land; lawns and fields; borders and clearings in forests and pine plantations; shores and river banks.
The distinctive calyx of this species is usually easy to see on young spikes (before the corolla lobes have spread), when turning back a bract near the base of the spike will reveal 2 fused sepals forming a slightly bilobed structure with each green midvein evident. The leaves vary from nearly glabrous to densely villous. Robust plants may have a dozen or more scapes. Leaves may be as broad as 4 cm, although usually they are much narrower.
