What to Eat
Edible parts: Fruit, Seed
Fruit - raw or cooked. More acid than a plum but it is very acceptable raw when fully ripe, especially after being touched by frost. The fruit is about 3cm in diameter and contains one large seed. Seed - raw or cooked. Do not eat the seed if it is too bitter - see the notes above on toxicity.
Known Hazards
Where to Find It
S. W. Asia. Naturalized and often considered a native of Britain.
EUROPE: Austria, Germany, Switzerland,
How to Identify
Prunus insititia is a deciduous Tree growing to 6 m (19ft) by 5 m (16ft) at a medium rate. See above for USDA hardiness. It is hardy to UK zone 5. It is in flower in April, and the seeds ripen in October. The species is hermaphrodite (has both male and female organs) and is pollinated by Bees, insects. The plant is self-fertile. It is noted for attracting wildlife. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in heavy clay soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil. The plant can tolerates strong winds but not maritime exposure.
How to Grow
Requires a well-drained moisture retentive soil. Succeeds in light shade but fruits better in a sunny position. Thrives in a loamy soil, doing well on limestone. Grows well in heavy clay soils. Prefers some chalk in the soil but apt to become chlorotic if too much is present. Occasionally cultivated for its edible fruit, there are some named varieties. It has been derived in cultivation from the bullace, differing in having a sweeter fruit. Damsons can be grown successfully against a north facing wall. 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. Prunus insititia L. is a synonym of Prunus domestica subsp. insititia (L.) Bonnier & Layens A sprouting standard sending up shoots from the base. Prunus insititia, commonly known as the damson plum, is generally considered self-fertile, meaning it can produce fruit without needing another tree for pollination. Harvesting typically occurs in late summer to early autumn, with specific timing varying by species. For instance, plums and peaches are usually harvested from July to September (Northern Hemisphere), while almonds are harvested in August to September (Northern Hemisphere). Prunus species usually flower in early spring, often between March and April (Northern Hemisphere), depending on the species and local climate. Growth rates vary among species, but generally, Prunus trees can grow moderately fast, often reaching full height in 3 to 5 years. However, they may take several years to bear fruit, depending on the species and growing conditions.
Propagation: Seed - requires 2 - 3 months cold stratification and is best sown in a cold frame as soon as it is ripe. Sow stored seed in a cold frame as early in the year as possible. Protect the seed from mice etc. The seed can be rather slow, sometimes taking 18 months to germinate. 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. Layering in spring.
Medicinal Uses
Febrifuge Purgative Styptic. The bark of the root and branches is febrifuge and considerably styptic. An infusion of the flowers has been used as a mild purgative for children. 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.
Other Uses
Dye Hedge Hedge Shelterbelt Agroforestry uses: Prunus species can be used as windbreaks and in alley cropping systems. They also improve biodiversity by providing habitats for pollinators and other wildlife. Some varieties can fix nitrogen in the soil, contributing to soil health. A green dye can be obtained from the leaves. A dark grey to green dye can be obtained from the fruit. Trees are fairly wind resistant and can be grown as a shelterbelt hedge.
