The Japanese plums were introduced into the U.S. during the latter part of the 19th century, and have become popular in our market. The fruit is medium to large for plums, 1.5 to over 2 inches in diameter. Shape is variable, but mostly conic to oval. Color generally light to dark red. Flesh generally soft and very juicy when ripe. Peel smooth, with waxy surface. Because these plums have high quality and will cross with American species they have been used in breeding to improve the quality of the hardy native types. Trees of Japanese plums are of medium size, and not very hardy to winter cold, hence commercial production is mainly in Calif.
Production in U.S.: About 100,000 tons.
Use: Mainly fresh market.
Part of fruit consumed: Generally all except pit. Peel may be separated from pulp in mouth and not eaten.
