What to Eat

Edible parts: Fruit, Seeds

The fruit can be eaten raw or cooked and measures approximately 11mm x 8mm, containing one large seed. The seed is also edible raw or cooked, but should not be eaten if it tastes excessively bitter.

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.

Where to Find It

It is a temperate plant. It is native to Japan. It grows in woods in mountains. It suits hardiness zones 4-9.

How to Identify

It is a deciduous tree. It grows 20 m tall. It is a broad spreading shape. The bark is glossy red-brown with pale lenticels. The leaves are narrowly oval and 12 cm long by 6 cm wide. They taper abruptly to a point. They have sharp teeth. Leaves are reddish when young and become glossy green above and are smooth on both sides. They turn brilliant orange and red in autumn. The flowers are 4 cm across and pink with 5 petals which have notches at the tip. The flowers are in clusters. The fruit is rounded or egg shaped and glossy purple-black. They are about 1 cm long.

How to Grow

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: Seed requires 2–3 months of cold stratification and is best sown in a cold frame as soon as it is ripe. Stored seed should be sown in a cold frame as early in the year as possible, with protection from mice. Germination can be slow, sometimes taking up to 18 months. Prick out seedlings into individual pots when large enough to handle, overwinter in a greenhouse or cold frame, and plant out in late spring or early summer the following year. Cuttings of half-ripe wood with a heel can be taken in July/August in a frame. Softwood cuttings from vigorous plants can be taken in spring to early summer in a frame. Layering can be done in spring.

Medicinal Uses

No specific research has been recorded for this species, but all Prunus members contain amygdalin and prunasin, which break down in water to release hydrocyanic acid (prussic acid or cyanide). In small amounts, this highly toxic compound can stimulate respiration, aid digestion, and produce a sense of well-being.

Other Uses

A green dye can be extracted from the leaves, and the fruit yields a dark grey to green dye.
