Briançon Apricot

Prunus brigantina

Physical Characteristics

Prunus brigantina is a deciduous Tree growing to 6 m (19ft 8in) at a medium rate. See above for USDA hardiness. It is hardy to UK zone 7. It is in flower in May, and the seeds ripen from August to September. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil.

Edible Uses

Edible Parts: Fruit Oil Seed Edible Uses: Oil Fruit - raw or cooked. A yellow plum about 3cm in diameter with a single large seed[K]. Scarcely edible according to one report[177], but we found it to have a pleasant mealy texture and a sweet flavour[K]. We have found it bearing quite freely, even on young trees no more than 6 years old[K]. An edible oil called 'huille des marmottes' is obtained from the seed[1, 2, 11, 46]. It is used as an olive oil substitute in France[105, 183]. Seed - raw or cooked. Do not eat the seed if it is too bitter - see the notes above on toxicity.

Medicinal Uses

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].

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.
