Prefers a rich loamy soil in a sunny position or semi-shade but thrives in any soil that is not water-logged, too dry or poor, though it is more wet-tolerant than other members of this genus. Grows well in heavy clay soils. Prefers an acid soil. Trees produce more and better quality fruits better when growing in a sunny position. All members of this genus have edible fruits and, whilst this is dry and uninteresting in some species, in many others it is sweet and juicy. Many of the species have potential for use in the garden as edible ornamentals. The main draw-back to this genus is that birds adore the fruit and will often completely strip a tree before it is fully ripe. There is at least one named variety of this species with superior fruits. 'Prince William' is a large multi-stemmed shrub to 3 metres tall and 2 metres across. It crops heavily and its good quality fruit is about 12mm in diameter. Considerable confusion has existed between this species and A. arborea, A. laevis and A. lamarckii, see for the most recent (1991) classification. Hybridizes freely with other members of this genus. Grafting onto seedlings of A. lamarckii or Sorbus aucuparia is sometimes practised in order to avoid the potential problem of hybridizing.
Edible fruit - raw or cooked. The fruit contains a few small seeds at the centre, it has a sweet flavor with a hint of apple. It can be eaten out of hand, used in pies, preserves etc or dried and used like raisins. We have found the fruit to be of variable quality, with some forms having a distinct bitterness in the flavor whilst others are sweet, juicy and delicious. When the fruit is thoroughly cooked in puddings or pies the seed imparts an almond flavor to the food. The fruit is rich in iron and copper. It is about 10mm in diameter. Trees can yield 7 to 15 tonnes per hectare.
Seed - it is best harvested 'green', when the seed is fully formed but before the seed coat has hardened, and then sown immediately in pots outdoors or in a cold frame. If stored seed is obtained early enough in the autumn, it can be given 4 weeks warm stratification before being left out in the winter and it should then germinate in the spring. Otherwise seed can be very slow to germinate, perhaps taking 18 months or more. When large enough to handle, prick the seedlings out into individual pots and grow them on in a sheltered outdoor position, planting them out once they are 20cm or more tall. If there is sufficient seed it is best to sow it thinly in an outdoor seedbed. Grow the seedlings on for two years in the seedbed before planting them out into their permanent positions during the winter. Layering in spring - takes 18 months. Division of suckers in late winter. The suckers need to have been growing for 2 years before you dig them up, otherwise they will not have formed roots. They can be planted out straight into their permanent positions if required.
Swamps, low ground, woods and thickets. Grows in woods and hedgerows in Britain.
