Prunus ursina (bear's plum, Arabic: خوخ الدب ) is a species of prunus native to the woods of Western Asia from Turkey to Syria, Israel and Lebanon. Some sources include this species in Prunus cocomilia.
Prunus ursina fruits better in full sun but is still successful in partial shade. The tree will form suckers if its shallow roots are damaged. Among the pests that affect the genus Prunus is honey fungus. The seed requires two–three (2–3) months cold stratification in order to germinate.
The fruit may be toxic if consumed excessively. Prunus plants contain amygdalin and prunasin, which break down in water to produce hydrogen cyanide. This is a colorless, extremely poisonous chemical that gives almonds their characteristic flavour. These substances are found mainly in the leaves and seed and can be detected by the 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.
The fruit can be used to obtain a dark grey to green dye and a green dye can be obtained from the leaves.
