The species is often found at higher elevations on dry and rocky surfaces such as cliffs, slopes, rocky outcrops, and granitic domes. Since it is a Ragwort, Packera millefolium, typically colonizes in patches in open habitats, and it thrives in environments that receive at least 870 mm of rainfall a year.
