Degraded prairies, railroads, open sandy ground. This prairie species is probably native at some sites in southern Michigan although others are dubious. A large colony between the highway and an abandoned railroad near the Emmet/Charlevoix Co. line, for instance, is presumably adventive, as is a 1900 collection from near a railroad in Manistee Co.

A hybrid with H. giganteus has been found once.
