A dark grey to green dye can be obtained from the fruit. A red dye can be obtained from the roots. This species is widely used as a rootstock for cultivated plums in North America. The tough, elastic twigs can be bound into bundles and used as brooms for sweeping the floor. Trees often grow wild along streams, where their roots tend to prevent soil erosion.Wood - heavy, hard, close-grained, strong. It weighs 45lb per cubic foot. Of no commercial value because the trunk is too small.
The bark is astringent, diuretic and pectoral. It has been used to make a cough syrup. An infusion has been used in the treatment of diarrhoea, kidney and bladder complaints. An infusion of the twigs has been used in the treatment of asthma.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.
Cuttings of half-ripe wood with a heel, July/August in a frame. Difficult, if not impossible. Softwood cuttings from strongly growing plants in spring to early summer in a frame. Difficult, it not impossible.Suckers in late winter.

Trees are probably hardy to as low as -50°c when fully dormant. A fast-growing but short-lived tree in the wild, it is cultivated for its edible fruit in N. America, where there are many named varieties. It flowers well in Britain but rarely fruits well here. Most members of this genus are shallow-rooted and will produce suckers if the roots are damaged. Plants often produce suckers at the roots and form thickets. The branches are brittle.Plants in this genus are notably susceptible to honey fungus.
