This species is found in dry or moist sandy soil and seems to prefer a prairie habitat. It is local to very local in the area shown on the map and is most abundant in a remnant prairie in Lagrange County. My specimens are all from roadsides and fallow fields.

Dry woods and prairies; e. Que. to Mack., s. to D.C., Ind., Mo., and Ariz. June, July. Ours is var. arguta. (Drymocallis agrimonioides)
