Sorbus hybrida (common name: swedish service tree)
Propagation: Seed - best sown as soon as it is ripe in a cold frame[1][2]. If you have sufficient seed it can be sown in an outdoor seedbed[1][2]. Stored seed germinates better if given 2 weeks warm then 14 - 16 weeks cold stratification[3], so sow it as early in the year as possible. Prick out the seedlings into individual pots when they are large enough to handle. Seedlings are very slow to put on top-growth for their first year or two[4], but they are busy building up a good root system. It is best to keep them in pots in a cold frame for their first winter and then plant them out into their permanent positions in late spring.
Cultivation: Succeeds in most reasonably good soils in an open sunny position[4]. Tolerates very acid or alkaline soils[4]. Tolerates light shade[5], though it fruits better in a sunny position[K].
Plants are susceptible to fireblight[5].
The trees usually have apomictic flowers. They thus produce seed asexually, each seedling being a clone of the parent[4].
Range: Europe - S. and S.W. Scandinavia.
Habitat: Usually found near the coast[4].
Edibility: Fruit - raw or cooked[6]. The fruit is up to 10 - 12mm across[7] and is produced in fairly large bunches, making harvesting easier[K].
Pollinators: Insects, apomictic
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Wind: Tolerates strong winds
Seed Ripens: Early Fall
Flower Type: Hermaphrodite
Known Hazards: The seeds probably contain hydrogen cyanide. This is the ingredient that gives almonds their characteristic flavour. Unless the seed is very bitter it should be perfectly safe in reasonable quantities. In small quantities, hydrogen cyanide has been shown
Also Known As: S. fennica. S. meinichii. S. pinnatifida. Crataegus fennica. Pyrus fennica. P. firma. P. pinnatifida.
