See text Pediocactus (Greek: πεδίον (pedion) means "plain", "flat", "field") is a genus of cacti native to the Western United States.

The Pediocactus genus includes small species of cactus that grow either individually or in clusters, reaching heights of up to 20 centimeters (7.9 in).

[2] The bell-shaped flowers at the top of the shoots come in colors ranging from yellow to magenta to white, with diameters of 1 to 2.5 centimeters (0.39 to 0.98 in).

These seeds ripen 4 to 6 weeks after flowering and remain viable for an exceptionally long period, lasting at least 10 years.

[2] As of January 2025[update], Plants of the World Online accepts the following species: The genus has 3 synonyms: Sclerocactus and Pediocactus were also at one time reduced to synonymy, but this is not at present considered to be correct.
