Where it grows wild

Like other small Notocactus of the Pampa, it grows in shallow soil in rock crevices and among grasses on low hills and outcrops, often partly shaded by grass tufts. Habitat details are inferred from the genus and region.

The two recorded sites sit near 300 m; the Pampa outcrops it grows on are mostly below 500 m.
