Prunus salicina - Lindl.
                 
Common Name Japanese Plum
Family Rosaceae
USDA hardiness 5-8
Known Hazards Although no specific mention has been seen for this species, it belongs to a genus where most, if not all members of the genus produce hydrogen cyanide, a poison that gives almonds their characteristic flavour. This toxin is found mainly in the leaves and seed and is readily detected by its bitter taste. It is usually present in too small a quantity to do any harm but any very bitter seed or fruit should not be eaten. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.
Habitats Sparse forests, forest margins, scrub, along trails in mountains, beside streams in valleys, thickets at elevations of 200 - 2600 metres[266].
Range E. Asia - China.

Edible Uses
Edible Parts: Fruit;  Seed.
Edible Uses:

Fruit - raw or cooked[46, 61, 105, 171]. The fruit ripens early[74]. A unique taste[74]. Sweet and juicy, it can be eaten out of hand, made into pies, preserves etc, or be dried for later use[183]. The fruit is very resistant to rotting[74]. The plum-shaped fruit is up to 7cm long and contains one large seed[200]. Seed - raw or cooked. Do not eat the seed if it is too bitter - see the notes above on toxicity.
Medicinal Uses

Stomachic.

The fruit is stomachic[240]. It is said to be good for allaying thirst and is given in the treatment of arthritis[240]. Although no specific mention has been seen for this species, all members of the genus contain amygdalin and prunasin, substances which break down in water to form hydrocyanic acid (cyanide or prussic acid). In small amounts this exceedingly poisonous compound stimulates respiration, improves digestion and gives a sense of well-being[238].
Other Uses
Dye.

A green dye can be obtained from the leaves[168]. A dark grey to green dye can be obtained from the fruit[168].
Cultivation details
Thrives in a well-drained moisture-retentive loamy soil[11, 200]. Prefers some lime in the soil but is likely to become chlorotic if too much lime is present[1]. Succeeds in sun or partial shade though it fruits better in a sunny position[11, 200]. This species does not grow well in Britain, the summers are not warm enough to properly ripen the wood and the springs are too unpredictable for the flowers to be fertilized[11]. An important temperate fruit tree, it is widely cultivated in China and other regions of Asia for its edible fruit, and is being increasingly grown in N. America[266]. There are several named varieties[46, 58, 183]. This species does not cross-pollinate with the English plum, P. domestica[200]. Most members of this genus are shallow-rooted and will produce suckers if the roots are damaged[238]. Plants in this genus are notably susceptible to honey fungus[200]. Special Features: Not North American native, All or parts of this plant are poisonous, Blooms are very showy.
Propagation
Seed - requires 2 - 3 months cold stratification and is best sown in a cold frame as soon as it is ripe[200]. Sow stored seed in a cold frame as early in the year as possible[200]. Protect the seed from mice etc. The seed can be rather slow, sometimes taking 18 months to germinate[113]. Prick out the seedlings into individual pots when they are large enough to handle. Grow them on in a greenhouse or cold frame for their first winter and plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood with a heel, July/August in a frame[11, 200]. Softwood cuttings from strongly growing plants in spring to early summer in a frame[200]. Layering in spring.

This tree, Prunus salicina, had the common name of Santa Rosa Plum at the vendor where I purchased it. Bailey's Manual of Cultivated Plants calls it the Japanese Plum even though it is native to China.

The "Santa Rosa Plum" was the hybrid invention of Luther Burbank (1849-1926).

It was developed by him in the 1880s from Japanese, European and American plum stocks and named after the town in which Burbank lived, Santa Rosa California USA.

I live in Alaska, where it is zone 3. I use the pr. salicina regularily for rootstock. Mr Lamers in Fairbands, zone 2 also uses them. I don't think zome 6 is accurate.
