Discussion | Prunus andersonii inhabits the Great Basin Desert region of central and western Nevada, ranging westward into California to the eastern slopes of the Sierra Nevada from Modoc County south to Inyo County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Double-flowered cultivars of Prunus glandulosa, which lack stamens and carpels, are commonly planted as foundation shrubs and in borders. Although the plants are attractive in bloom, some horticulturalists consider them of little ornamental value otherwise.
