COUNTRY OF ORIGIN AND NATIVE HABITAT
Japanese apricot is native to China. Trees grow in woods and rocky hills in moist, well-drained soils. Although P. mume is from China, it was first observed in cultivation in Japan. The tree was chosen the national flower of China in the 1930s. In China, the 5 petals represent the 5 blessings: wealth, health, love of virtue, old age and natural death. Japanese apricot is a member of the Rosaceae family. The Rosaceae family includes some 200 species.
