The word is not native Latin, but is a loan from Greek προῦνον ("prounon"), which is a variant of προῦμνον ("proumnon"), origin unknown. The tree is προύμνη ("proumnē"). Most dictionaries follow Hoffman, "Etymologisches Wörterbuch des Griechischen", in making some form of the word a loan from a pre-Greek language of Asia Minor, related to Phrygian. The first use of "Prunus" as a genus name was by Carl Linnaeus in "Hortus Cliffortianus" of 1737, which went on to become "Species Plantarum". In that work, Linnaeus attributes the word to "Varr.", who it
Prunus simonii is particularly aromatic, much more so than "Prunus salicina", with a comparatively high level of hexyl acetate, which gives apples their aroma. Plant breeder Luther Burbank devoted a lot of work to hybridizing this species with the Japanese plum ("Prunus salicina") and developed a number of cultivars from the hybrid. Of these, the cultivar 'Climax' was particularly notable for its importance to the fruit shipping industry of California. Other influential plum cultivars that Burbank developed with "P. simonii" ancestry include 'Maynard', 'Chalco', 'Santa Rosa', and 'Formosa'. Those two species and the European species "Prunus cerasifera" have contributed the majority of
