Krigia occidentalis grows in the Eastern deciduous forest biome, tallgrass prairie, and mixedgrass prairie. It has superficial similarity in pappus form to K. virginica; it was consistently placed as the sister species to K. cespitosa in chloroplast cpDNA and nuclear rDNA studies by K. J. Kim et al. (1992b, 1992c). In morphology, it is most similar to the polyploid species K. wrightii, with 2n = 18.
