Prunus humilis (common name: bush cherry)

Propagation: Seed - requires 2 - 3 months cold stratification and is best sown in a cold frame as soon as it is ripe[1]. Sow stored seed in a cold frame as early in the year as possible[1]. Protect the seed from mice etc. The seed can be rather slow, sometimes taking 18 months to germinate[2]. Prick out the seedlings into individual pots when they are large enough to handle. Grow them on in a greenhouse or cold frame for their first winter and plant them out in late spring or early summer of the following year.

Cuttings of half-ripe wood with a heel, July/August in a frame[3][1].

Softwood cuttings from strongly growing plants in spring to early summer in a frame[1].

Layering in spring.

Cultivation: Requires a well-drained moisture retentive soil[3][1]. Requires a sunny position[3]. Thrives in a loamy soil, doing well on limestone[3]. Prefers some chalk in the soil but apt to become chlorotic if too much is present[4].

The bush cherry is sometimes cultivated for its edible fruit in China[3][5].

This species is closely related to P. glandulosa[3].

Most members of this genus are shallow-rooted and will produce suckers if the roots are damaged[6].

Plants in this genus are notably susceptible to honey fungus[1].

Range: E. Asia - N. China.

Habitat: Thickets, mountain slopes and sunny sandy slopes at elevations of 400 - 1800 metres[5].

Edibility: Fruit - raw or cooked[7]. Acid but not unpalatable[3]. Very sour according to another report[8]. A reasonable size, it is up to 13mm in diameter and contains one large seed[1].

Seed - raw or cooked. Do not eat the seed if it is too bitter - see the notes above on toxicity.

Medicinal: The seed is aperient and diuretic. It lowers blood pressure[9]. It is used in the treatment of constipation and oedema[9].

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[6].

Usage: A green dye can be obtained from the leaves[10].

A dark grey to green dye can be obtained from the fruit[10].

Pollinators: Insects

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

Seed Ripens: Mid Summer-Mid Fall

Flower Type: Hermaphrodite

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

Also Known As: P. bungei.
