''Prunus subcordata'', known by the common names Klamath plum, Oregon plum, Pacific plum and Sierra plum, is a member of the genus ''Prunus'', native to the western United States in California and western and southern Oregon.〔Little. ''Atlas of United States Trees, Volume 3, Minor Western Hardwoods'', Map 126, ''Prunus subcordata''.〕 It grows in forests, most often at low elevation near the coast, but it is also in the Sierra Nevada and Cascades; it grows at altitudes of 100–1,900 m.〔(Jepson Manual. University of California: ''Prunus subcordata'' )〕〔USDA Plants Profile: (''Prunus subcordata'' )〕 ''P. subcordata'' var. ''subcordata'', Klamath plum, is also found in Washington.〔〔(Biota of North America Program 2014 county distribution map )〕〔(Calflora taxon report, University of California, ''Prunus subcordata'' Benth. Klamath plum, Sierra plum )〕 The range of ''Prunus 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.〔Little. ''Atlas of United States Trees, Volume 3, Minor Western Hardwoods'', Maps 121, 122-N, 122-W, & 123, ''P. fremontiii'', ''emarginata'', & ''ilicifolia''.〕〔 ==Plant description== ''Prunus subcordata'' is an erect deciduous shrub or small tree growing to 8 m (nearly 27 feet) in height. It sprouts from its roots and can form dense, spiny thickets. The bark is gray with horizontal brown lenticels, similar in appearance to that of the cultivated cherry tree. The leaves are 2.5–5 cm (1-2 inches) long with a 4–15 mm (0.16-0.60 inch) petiole, dark green, turning red before falling, and are faintly toothed. The flowers are white or pinkish, appearing in the spring in clusters of one to seven together. The fruit is a small, plum-like drupe, variable in appearance, 15–25 mm (0.60-1.00 inch) in length, and may be red or yellow; they mature in late summer. The plums are small and tart but edible.〔〔Casebeer, M. (2004). ''Discover California Shrubs''. Sonora, California: Hooker Press. ISBN 0-9665463-1-8〕〔(Flora of North America, ''Prunus subcordata'' Bentham, 1849. Sierra or Klamath or Pacific plum )〕 The three main common names are related to the plum's mountain ranges and locales. The Concow tribe call the tree gos’-i (Konkow language).
