Opuntia aurea Opuntia aurea grows in southern UT and perhaps northern AZ. It is prostrate and forms irregularly sprawling plants to about 3-ft across. Occasionally a single pad may grow upright. The plants are spineless or have a few spines to multiple spines. Spines may be in the distal areoles only. Some botanists contend that plants with spines are hybrids and not pure O. aurea.
