Prunus arabica aka Bitter Almond

Prunus arabica belongs to the rose family, Rosaceae. It grows as a shrub or tree and sheds its leaves. Its native range runs from Türkiye to northern Iran and Arabia. Records also place it in Iraq, Syria, Israel, and Jordan. In Arabia, it occurs in Oman and northwestern Saudi Arabia. Kew places it within the subtropical climate zone. Its wild habitats include dry steppe and open oak woods.

The plant flowers in May, according to Plants For A Future. Each flower has both male and female organs. Insects pollinate the flowers. The fruit holds one large seed. The supplied sources give no firm garden height or spread. They also give no species-level details of bark or leaf shape. These gaps limit a fuller account of its form.

For garden use, choose soil that drains well but holds some moisture. Loam suits it, though sand and clay are also listed. It accepts mildly acid, neutral, and mildly alkaline ground. Some lime suits it, but excess lime may cause chlorosis. It grows in full sun or partial shade. A sunny site helps it bear more fruit. It accepts dry or moist soil. Its dry native habitat also suggests scope for dry-site planting. A sunny woodland edge is one suggested garden setting.

Plants For A Future lists both fruit and seed as food. It records raw and cooked uses for each. The same source warns against eating very bitter seeds or fruit. Its cyanide warning draws on the genus, not confirmed species-specific findings. The food listing should therefore not imply proven safety. Leaves can yield green dye. Fruit can yield shades from dark grey to green. People also sell gum from this plant in local markets. The source does not confirm which parts supply that gum.

Seed propagation may need patience. Give seed two to three months of cold treatment. Sow fresh seed in a cold frame when ripe. Stored seed can go into a cold frame early in the year. Germination can take as long as eighteen months. Protect the seed from mice. Keep young plants under cover through their first winter. Plant them out in late spring or early summer. Other methods include spring layering and cuttings taken during active growth.
