About
Pediocactus paradinei, also known as bristly plains cactus, Houserock Valley cactus, Kaibab pincushion cactus, Paradine cactus, and Park pincushion cactus is a rare species of cactus found in Arizona.
Where it grows
Endemic to the desert on the Kaibab Plateau in Houserock Valley, Coconino County, Arizona, Pediocactus paradinei is found at elevations ranging from 1600 to 2000 meters. It mainly grows in open woodland areas beneath Ponderosa pine trees, as well as in shrubland/chaparral within open pinyon-juniper woodlands and sagebrush valleys on Kaibab limestone gravels. Often found in small, scattered patches, it shares its habitat with other plant species such as Sclerocactus whipplei subsp. busekii, Escobaria missouriensis subsp. marstonii, Escobaria vivipara subsp. kaibabensis, Echinocereus engelmannii var. variegatus, Opuntia, and Yucca baccata.
