Habitat

Mostly found in anthropogenic habitats, including agricultural fields, roadsides and railroads, vacant lots, and other disturbed ground. Occasionally grows in lawns; the basal rosette can always survive mowing, but the blooming period is late enough that the plant usually cannot complete its life-cycle before mowing starts. Uncommon in intact ecosystems.
