Cultivation
Thrives in a well-drained moisture-retentive loamy soil, doing well on limestone. A very hardy plant, probably tolerating temperatures down to about -50°c when it is fully dormant. It is cultivated for its edible fruit in warmer climes than Britain. 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 cold stratification and is best sown in a cold frame as soon as it is ripe. 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. Softwood cuttings from strongly growing plants in spring to early summer in a frame. Division of suckers in the dormant season. They can be planted out direct into their permanent positions. Layering in spring.
Edible uses
Fruit - raw or cooked. 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.
Material uses
A green dye can be obtained from the leaves. A dark grey to green dye can be obtained from the fruit. The plant can be used as a rootstock for plums.
Habitat
Sandy hills, open plains, rocky slopes or shores.
Native range
Central N. America - Manitoba and Minnesota to Kansas and Utah.
