As summer’s flowers fade, plants that produce berries take center stage. Branches covered with bright red berries make cotoneasters especially attractive now, but they offer year-round interest. In spring, tiny but abundant white to pink flowers may be obscured by the shiny round green leaves. Foliage turns orange-red in fall. Finally, the berries persist into winter, or until the birds pick them clean.
The hardest part of growing cotoneaster is pronouncing it correctly (it’s “ko-TON-ee-AS-ter”). These shrubs thrive with little attention, handling poor soils, full sun to afternoon shade, and moderately low amounts of water. New shrubs should be coddled a bit until vigorous growth begins. Give plants room to spread, pruning only to remove oldest wood and enhance appearance. As with all members of the rose family, cotoneasters are occasionally susceptible to fire blight; some new varieties are tolerant of this disease. The many different species in cultivation vary in hardiness. Most will survive zone 4 or 5 winters, but check the label for the variety you are purchasing.
There is a size and shape for every use. Spreading plants under three feet high make good groundcovers. Try planting them where their arching branches can spill over a wall. Small, stiffly erect shrubs may be used as informal hedges. Tall, fountain-shaped growers form good screens.
