Safety & Hazards

Although no specific mention has been found for this plant. it belongs to a family where the leaves, seed (and sometimes also the fruit) often contain significant amounts of hydrogen cyanide. This is the toxin that gives almonds their characteristic flavour and it should only be eaten in very small quantities. Since the fruit of this species is said to have almond-scented fruit it would be unwise to eat a large quantity of it. 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.

Cultivation Details

HabitDeciduous Shrub
Growth—

Succeeds in an ordinary well-drained garden soil[1, 2], but becomes chlorotic on shallow soils over chalk[2]. Prefers a well-drained moisture retentive soil in a shady position[2]. Requires a sunny position according to another report[3]. Plants are hardy to about -20°c[4]. This species grows well in a woodland garden or in a damp shady border[2]. The plants often sucker freely and can form dense thickets[5]. Old plants can be rejuvenated by cutting them back hard into the old wood in late winter, they will resprout freely from the base[2]. Growth can be restricted by removing suckers and cutting old shoots back or down to the base in late winter[5]. Some, if not all plants are A dioecious species - both male and female forms must be grown if fruit and seed are required.

Propagation

The seed requires 4 months stratification at 4°c. It is probably best sown in a cold frame as soon as it is ripe in the autumn. Sow stored seed as early in the year as possible. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, mid summer in a frame. Layering in spring. Takes 6 months[6]. Suckers, taken at any time in the dormant season[5]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Oemleria+cerasiformis>
