Esteve's pincushion is native to California and the Great Basin of the United States and the southwestern deserts extending into Mexico, where it grows in open arid and semiarid habitat. According to Flora of North America, it is "among the most abundant spring wildflowers in the higher Mojave Desert and southern Great Basin."[2] It is also found in the southern California chaparral and woodlands habitats.
