Prunus x utahensis is a deciduous shrub found in areas such as A hybrid of garden origin, P. angustifolia watsonii x P. besseyi[200]. A member of the Rosaceae family, Prunus x utahensis Koehne does not go by a known (to us) common name. The shrub can grow to a height of 1.5 meters and up to meters wide. The preferred habitat of Not known in the wild., with LMH soil and SN moisture levels. .

The plant is a zone 4 hardy plant that has medicinal uses - the medicinal usage rating of is 1Although 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[238].

Prunus x utahensis is a non flowering plant which is pollinated by Insects.

Known hazards of the plant: 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.

The plant has an edibility rating of 2Fruit - raw or cooked[177]. The fruit contains a single large seed. Seed - raw or cooked. Do not eat the seed if it is too bitter - see the notes above on toxicity.

Cultivation tips: Thrives in a well-drained moisture-retentive loamy soil[11, 200]. The plant prefers some lime in the soil but is likely to become chlorotic if too much lime is present[1]. Succeeds in sun or partial shade though it fruits better in a sunny position[11, 200]. Most members of this genus are shallow-rooted and will produce suckers if the roots are damaged[238]. Plants in this genus are notably susceptible to honey fungus[200].

. The plant should best be propagated by Seed - requires 2 - 3 months cold stratification and is best sown in a cold frame as soon as it is ripe[200]. Sow stored seed in a cold frame as early in the year as possible[200]. Protect the seed from mice etc. The seed can be rather slow, sometimes taking 18 months to germinate[113]. 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. A hybrid species, it will not breed true from seed. Cuttings of half-ripe wood with a heel, July/August in a frame[11, 200]. Softwood cuttings from strongly growing plants in spring to early summer in a frame[200]. Layering in spring.

Fruit - raw or cooked[177]. The fruit contains a single large seed. Seed - raw or cooked. Do not eat the seed if it is too bitter - see the notes above on toxicity.
