How to grow
Shiro is productive in most climates, including the low-chill climates of California where it was developed. It is partially self-fertile, and a good pollenizer of many other Japanese plum varieties.
Although a regular bearer, Shiro has a tendency to over-crop, which will lead to smaller fruits. To avoid this be sure to thin out the fruitlets after the blossom has set - the remaining fruits will be larger and have a better flavor.
Advice on fruit tree pollination.
Shiro was developed by the famous Californian fruit breeder Luther Burbank in the late 19th century. He was one of the first to import Japanese plum seedlings and hybridize them with other plum species, including native North American species. Shiro was introduced in 1899, and remains a popular variety today, as well as being used in the development of many other Japanese-style plums.
