Plants can be used as a windbreak hedge in all but the most exposed positions, they tolerate trimming[9]. A rose-tan dye is obtained from the berries.

Propagation

Seed. Members of this genus hybridize freely so, if you require seed that breeds true, it is important to obtain it from a known wild source or from a controlled fertilization of garden plants. The seed is best sown as soon as it is ripe in the autumn in a cold frame, when it will usually germinate in the spring[2][6]. Stored seed germinates faster if given 3 months warm stratification at 15°c and then 3 months cold stratification at 4°c[3]. The seed usually germinates within 1 - 18 months at 15°c but it can take 2 years[3]. Pot the seedlings up as soon as they are large enough to handle and plant them out into nursery beds or into their permanent positions when they are more than 10cm tall. Cuttings of half-ripe wood with a heel, July/August in a frame[2][6].
Cultivation
This section contains historical Plants For A Future notes marked noncommercial.
An easily grown plant, it prefers a good soil but also does well in poor soils[1][2][6]. It thrives in lime and is also happy in peaty soils[1]. It succeeds in any soil that is not marshy or waterlogged[2][6]. Succeeds in dry soils[5]. Grows well in heavy clay soils. Succeeds in full sun or semi-shade but does not fruit so freely in a shady position[2][6]. Tolerates atmospheric pollution[6]. Fairly tolerant of maritime exposure[9]. This species is hardy to about -15°c[4]. Plants are defoliated in cold winters[7]. A very ornamental plant[1]. There are a number of named forms selected for their ornamental value[6]. 'Cornubia' is a fast-growing form that has been recommended for hedges in exposed positions[9]. Hybridizes freely with other members of this genus[6]. The flowers, when inhaled near to, have an unpleasant smell like decaying fish[8]. They are very attractive to bees whilst the fruit is a good winter food source for many species of birds[6]. Trees are notably susceptible to honey fungus[6].
