Hedeoma diffusa is a species of flowering plant in the mint family known by the common names spreading false pennyroyal and Flagstaff false pennyroyal. It is endemic to Arizona in the United States.[1][2]

This perennial herb has spreading, prostrate stems that form a mat on the ground. The leaves are oppositely arranged. The flowers are blue to lavender in color and are open for about three days. Blooming occurs in May through September.[2]

This plant is limited to northern Arizona, occurring in Navajo, Coconino, and Yavapai Counties.[1] It grows on Kaibab Limestone, in and around rocky cracks and crevices. In Oak Creek Canyon in the Red Rock-Secret Mountain Wilderness Area, sites are considered protected, and most are inaccessible.[2]
