Sorbus devoniensis (common name: french hales)

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 light shade[5], though it fruits better in a sunny position[K].

At one time the fruits of this species were collected and sold in local markets in S.W. England[4][6].

Plants are susceptible to fireblight[5].

It is part of the aggregate species S. latifolia, it breeds true because its seed is produced apomictically[7].

Range: Southwestern Britain.

Habitat: Old woods in south-western England[8]. Probably a hybrid species with S. torminalis in its blood[4].

Edibility: Fruit - raw or cooked. The fruit is usually bletted if it is going to be eaten raw[9][8][4]. This involves storing the fruit in a cool dry place until it is almost but not quite going rotten. At this stage the fruit has a delicious taste, somewhat like a luscious tropical fruit[K]. The fruit is up to 15mm across[10] and is produced in bunches which makes 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-Mid 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
