The base of the leaf is wedge-shaped, and its apex ranges from acute (pointed) to caudate (having a slender short tail).

[5] The winter buds of the Prunus salicina are purplish red, and are occasionally hairy at scale margins, though this is rare.

[12] Ectomycorrhizal relationships with the fungus Hebeloma hiemale was shown to increase net growth in Prunus cerasifera  x salicina, compared to chemical fertilizer, compost and a control.

A study conducted in Guiyang Karst Park, Guizhou, China, concluded that Prunus salicina, in combination with the moss species, Homomallium plagiangium, Cyrto-hypnum pygmaeuman and Brachythecium perminusculum, and the herbs Veronica arvensis and Youngia japonica, were suitable pioneer plant species to cultivate for use in restoration of regions of karstic soil erosion.

[15] The main producing country of Japanese plums is China, followed by the United States of America, Mexico, Italy, Spain, Pakistan, Korea, Australia, Chile, France, South Africa and Argentina.

The most famous variety of this fruit in Vietnam is the Tam Hoa plum grown in Bắc Hà town, in Lào Cai Province.

In the late 19th and early 20th centuries, from these hybridizations Burbank selected cultivars such as ‘Beauty’, ‘Eldorado’, ‘Formosa’, ‘Gaviota’, ‘Santa Rosa’, ‘Shiro’, and ‘Wickson’, some of which are still widely grown.

They are grown on a large scale in a number of other countries, for example, they dominate the stone fruit industry in Western Australia.

As a result, the Community Plant Variety Office of the European Union (CPVO) registered 155 new Japanese plum cultivars from 1995 to 2021.

[11] The IUCN Red List recommends "the incorporation of population management and monitoring in protected areas where this species is known to occur" and "additional ex situ collection, ensuring the full range of genetic diversity found in the wild is represented in genebanks.

fruit has a short-shelf life (3–4 days) under room temperature as well as cold storage (1–2 weeks), it is often prepared into jams, jellies, wine, and other beverages.

The Santa Rosa plum cultivar produces the best quality wine, in comparison Methley, and Green Gage.

A study on foraging in the Gongba Valley (Zhouqu county in Gansu, China) identified Prunus salicina as one of the most commonly eaten wild fruits.

[33] In Japan, while it is less commonly eaten than closely related Prunus mume, it is pickled and colored in a similar manner.

[39][40] A study evaluating ethanol extracts from 400 herbs found that the Japanese plum was the most effective Glucosyltransferase (GTF) inhibitor and showed the highest antibacterial activity.
