It is known by many common names, including Australian blackthorn, blackthorn, Christmas bush, mock orange, native blackthorn, native box, native olive, prickly box, prickly pine, spiny box, spiny bursaria, sweet bursaria, thorn box and whitethorn. Summer flowering has given rise to the name (Tasmanian) Christmas bush in Tasmania and South Australia (not to be confused with "Prostanthera lasianthos"). Indigenous names recorded include "kurwan" in Coranderrk, Victoria, and "geapga" from Lake Hindmarsh Station. "Bursaria spinosa" is highly variable in appearance and habit, as are other species within the genus, and there
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
