Summary
Source: WikipediaPrunus korshinskyi is a deciduous shrub reaching 3.5 m with hermaphroditic flowers pollinated by insects. The plant grows in light sandy, medium loamy, and heavy clay soils with good drainage, tolerating mildly acidic, neutral, and basic soil pH. It adapts to semi-shade or full sun and prefers moist soil conditions.
Description
Prunus korshinskyi is a deciduous shrub reaching 3.5 m with hermaphroditic flowers pollinated by insects. The plant grows in light sandy, medium loamy, and heavy clay soils with good drainage, tolerating mildly acidic, neutral, and basic soil pH. It adapts to semi-shade or full sun and prefers moist soil conditions.
Edible Uses
Seeds are edible raw or cooked and can be used as an almond substitute. However, seeds are typically bitter and should not be consumed in large quantities due to toxicity concerns.
Traditional Uses
The dried seed are added to the surface of cooked rice. The seeds are cooked and added to food. The fruit are preserved in salt solution pickles.

Medicinal Uses
All Prunus species contain amygdalin and prunasin, which hydrolyze in water to produce hydrocyanic acid. Though extremely toxic, small amounts stimulate respiration, enhance digestion, and promote general well-being.
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.
Distribution
Temperate.
Where It Grows
Europe, Lebanon, Mediterranean, Middle East, Palestine, Turkey, Türkiye,
Cultivation
We have very little information on this species and do not know how hardy it will be in Britain, though judging by its native range it should succeed outdoors at least in the milder parts of this country. This species probably hybridizes with P. dulcis, the almond, and could be used in breeding programmes. The following notes are based on the general needs of the genus. Thrives in a well-drained moisture-retentive loamy soil. Prefers some lime in the soil but is likely to become chlorotic if too much lime is present. Succeeds in sun or partial shade though it fruits better in a sunny position. Most members of this genus are shallow-rooted and will produce suckers if the roots are damaged. Plants in this genus are notably susceptible to honey fungus.
Propagation
Seeds require 2-3 months cold stratification and are best sown in a cold frame immediately after ripening or as soon as possible in the season if stored. Protect seeds from rodents. Germination can be slow, taking up to 18 months. Move seedlings to individual pots when large enough, maintain in greenhouse or cold frame during the first winter, then transplant in late spring or early summer. Alternative methods include half-ripe wood cuttings with heel in July/August, softwood cuttings from spring to early summer, or spring layering.
Other Uses
Leaves produce green dye, fruit yields dark grey to green dye.
Notes
There are about 200 Prunus species.
