Prunus americana (American or wild plum) is found in the eastern United States.

The three main common names are related to the plum's mountain ranges and locales.

The species is native to Northern California and from central to western and southern Oregon.{{cite book |last=Little Jr. |first=Elbert L. |title=Atlas of United States Trees |publisher=US Government Printing Office |year=1976 |volume=3 (Minor Western Hardwoods) |entry=Map 126, Prunus subcordata |lccn=79-653298 |oclc=4053799 |entry-url=https://archive.org/details/atlasofunitedsta1314litt/page/n203/mode/1up}} It grows in forests, most often at low elevations near the coast, but is also found in the Sierra Nevada and Cascades. It grows at altitudes of {{Convert|100–1,900|m|abbr=on|sp=us}}.

The range of P. subcordata surrounds the San Joaquin Valley, especially the western flank foothills of the Sierra Nevada range, but avoids the coast mountains of the southwest San Joaquin Valley. For other Pacific coastal Prunus species, P. emarginata is also found in the Pacific Northwest states; P. fremontii and P. ilicifolia are found in coastal or mountain areas of southwest California and northern Baja California.{{cite book |last=Little Jr. |first=Elbert L. |title=Atlas of United States Trees |publisher=US Government Printing Office |year=1976 |volume=3 (Minor Western Hardwoods) |entry=Maps 121, 122, and 123, P. fremontiii, emarginata, ilicifolia |lccn=79-653298 |oclc=4053799 |entry-url=https://archive.org/details/atlasofunitedsta1314litt/page/n196/mode/1up}}

Various animals eat the fruit and thus spread the seeds.

The berry is considered edible.

The Concow tribe call the tree gos’-i (Konkow language).{{cite book |last1=Chesnut |first1=Victor King | author1-link=Victor King Chesnut |url=https://books.google.com/books?id=vLkUAAAAYAAJ |title=Plants used by the Indians of Mendocino County, California |publisher=Government Printing Office |year=1902 |page=405 |accessdate=24 August 2012}}
