Large prunus (ornamental cherry)

These deciduous trees range from 4m to over 12m in height, and may be spreading, rounded or narrowly upright. Flowers are borne in clusters along the branches, and may be single, semi-double or fully double, and sometimes lightly fragrant. These clouds of white through to deep pink blossom appear before, or just as, the leaves emerge. Many ornamental cherries have good autumn colour, and others display richly coloured, smooth, polished bark, most noticeable once the leaves have fallen.

Grow in moist but well-drained, moderately fertile soil. A sunny, open position is best for a good blossom display. Shelter from strong winds will help prevent damage to the flowers. Trees will develop a more elegant shape if allowed plenty of room to develop.

Do not plant in poorly drained or waterlogged soils, which can lead to root problems and poor growth. They also struggle in very dry soils. Avoid frost pockets, especially for very early flowering varieties. Heavy pruning, especially in winter, may increase the risk of disease.

The famous cherry blossom displays of Japan, known as sakura, are celebrated during the tradition of hanami – flower viewing – a cultural practice dating back centuries. RHS Garden Wisley has a beautiful display of spring cherry blossom from early March to mid-April.
