Most characteristic of disturbed, open ground in steep hillside and blufftop dry prairies but also on rock outcrops, dry cliffs, cedar glades, thin oak-hickory or oak-pine woods, sandy river islands; also in dry fields, along roadsides, sandy lawns, sand and gravel pits, railroad corridors, and other open, disturbed, sandy areas.
This is a rather weedy annual that has no doubt expanded its range thanks to the creation of suitable habitat by humans. Mostly found within the confines of the Driftless Area, but also extending into the sandy soils of the far northeast. Absent or rare in the far northwest and Northland Highlands as well as most of the eastern part of the state.
