ウメ
"Prunus salicina" should not be confused with "Prunus mume", a related species also grown in China, Japan, Korea and Vietnam. Another tree, "Prunus japonica", is also a separate species despite having a Latin name similar to "Prunus salicina"'s common name. 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.
