There are a considerable number of these popular ornamental shrubs, both evergreen and deciduous. They range from mat-forming types that are ideal for ground cover, to sizeable shrubs and trees.
One very popular low-growing cotoneaster is Cotoneaster conspicuus ‘Decorus’ (AGM), which is a good subject for covering banks or difficult spots. In early summer it produces masses of small, whitealong the entire length of its branches. These are followed by equally as many long-lasting bright red berries.
Also very useful for the same purpose is Cotoneaster horizontal’s (AGM). Here again with white flowers, but the orange-red berries are accompanied by richly coloured autumn foliage.
Much larger, in due course growing into a small tree, is Cotoneaster frigidus ‘Cornubia’ (AGM). This has dark foliage and masses of red berries. ‘Hybridus Pendulus’ is another that is widely available. It has glossy foliage and white flowers on long, prostrate branches; in autumn and winter it carries masses of red berries. It can be grown on a stem to form a small weeping tree. The majority of cotoneasters produce red berries, but there are exceptions, one being Cotoneaster salicifolius ‘Rothschildianus’ (AGM) with yellow fruits.
Soil type Most well-drained garden soils, but they will not tolerate wet conditions.
Planting Plant in autumn or spring, in an open, sunny spot.
Maintenance Regularis not required. Unwanted or damaged branches can be removed: with deciduous varieties this should be carried out in mid-winter, the evergreens should be tackled in early spring.
Propagation Cuttings of 7cm (3in) in length, with a heel, should be taken in mid-summer Root them in the usual manner.
Pests and diseases Aphid and scale insect attacks can be dealt with by insecticide. Cotoneasters can also be subject to certain fungal diseases which in mild cases cause die-back, and in severe cases cause the plant to fail completely.
