On dry sandy or clayey soil in fields, dry prairies, barrens, railroad embankments, open oak and jack pine woodlands, sand dunes, and limestone alvars. Most Wisconsin specimens represent the diploid subspecies nemoralis, common throughout the state. Distinguishing features of this subspecies include involucres less than 4.5 mm high, achenes short strigose, lower cauline leaves less than 7 times as long as wide, and basal leaves crenate. The tetraploid subspecies decemflora (DC) Brammal ex Semple, with involucres more than 4.5 mm, achenes long sericeous, lower cauline leaves more than 7 times as long as wide, and basal leaves entire, occurs mostly south of the Tension Zone. These two well-defined varieties are sometimes treated as distinct species.
