A large group of deciduous trees and evergreen shrubs that produce masses of showy flowers in spring. Many deciduous forms provide good autumn foliage colour. The genus includes flowering (ornamental) versions of almond, blackthorn (sloe), apricot, cherry, cherry laurel, peach, plum and Portugal laurel (cherry bay).
Family: Rosaceae (rose)
Botanical Name: Prunus
Common Names: Flowering cherry, ornamental cherry, cherry blossom.
Foliage: Oval, long pointed, green or red-purple leaves.
Flowers: Prolific white or pink blossom. Single or double.
Flowering Period: Spring.
Soil: Moderately fertile, moist but well-drained soil (chalk, clay, sand or loam). Acid, alkaline or neutral pH.
Conditions: Full sun. Can be grown in an east, south or west facing aspect in either an exposed or sheltered location.
Habit: Tall, bushy.
Type: Shrub or small tree.
Hardiness: Fully hardy in the UK (down to -20°C). Note: Blossom can be damaged by late frosts.
Prunus will usually do well in any well cultivated soil type except for highly acidic or water-logged conditions.
Plant early flowering forms in a sheltered site to protect the blooms from spring winds and late frosts. Later flowering forms make ideal specimen trees, which can be grown by themselves in the lawn or with other trees and shrubs. Most prefer an open sunny position but can usually tolerate a little light shade. Only the evergreen species will tolerate dense shade.
Shrubby forms can grown as a flowering hedge or screen. However, cherry trees are not recommended for the herbaceous border due to their tendency to form suckers.
Container-grown specimens are best planted in early autumn to late spring. Hedging plants should be set about 18in (45cm apart.
Water well until established.
Pruning of most forms is not necessary. However, cut back the young shoots of P. glandulosa and P. triloba to two or three buds after flowering if you want to keep these shrubby forms in check. Deciduous hedges can be trimmed after flowering.
Susceptible to attack by aphids and caterpillars. Bullfinches may eat flower buds.
Can be affected by a wide variety of diseases, including pocket plum, silver leaf, honey fungus, peach-leaf curl, bacterial canker and blossom wilt.
Sow seed of deciduous species in the autumn. Large-flowering trees are normally propagated by grafting to a suitable rootstock. Small trees, hybrids forms and shrubs can be propagated by striking 3in (8cm) cuttings in a cold frame in July.
