It is native to North America, where it is found primarily in the areas of the Great Plains and Ozark and Ouachita Mountains in United States. Its natural habitat is on glades, sandy areas, or bluffs with rock outcrops, typically on acidic substrates (although rare populations on calcareous substrates are known).

It produces pink-red to red-purple flowers from May to October. The Latin specific epithet calycinus means calyx-like. A synonymous name for Phemeranthus calycinus is Talinum calycinum.
