Heteromeles arbutifolia is widely distributed in the Coast Ranges north to Humboldt County and in a more scattered manner in the Sierra Nevada to Shasta County. Plants are used for Christmas decoration in the flora area and are sometimes cultivated for ornament where the species prospers.

Two varieties have been named, var. cerina (= Photinia arbutifolia var. cerina), which represents yellow-fruited forms, and var. macrocarpa (= P. arbutifolia var. macrocarpa), with more floriferous inflorescences and larger fruits (8–10 mm). The first is a sporadic variant worthy only of forma status; the variety named by Munz is more substantial, seems usually to have shorter and relatively broader leaves with barely toothed, revolute margins, and is said to be most common on the Channel Islands of San Clemente and Santa Catalina. This variety seems to intergrade with var. arbutifolia, which represents the bulk of the species.
