Which Flowering Cherry Tree for my Garden?
Japanese Flowering Cherries, Prunus pendula, Prunus sargentii, Prunus serrulata, Prunus x yedoensis, Prunus x subhirtella
The cherry blossom (sakura) is Japan's unofficial national flower. Celebrated for centuries, it is esteemed as the most beautiful and important of flowers in Japanese culture. In spring, during the blossom-viewing season called Hanami, flowering cherries are celebrated with huge festivals, parties, and family picnics wherever the cherries grow.
The term “flowering cherry” refers to seven species of Prunus (Prunus campanulata, P. incisa, P. jamasakura, P. serrulata, P. sargentii, P. spachiana (syn. subhirtella), and P. speciosa) and their cultivars. According to the Flower Association of Japan, there are over three hundred species, varieties, and hybrids of Japanese flowering cherries. These flowering cherries come in a wide variety of sizes and shapes and several are excellent additions to the garden. All are incredibly beautiful.
Several characteristics are differentiating the many cherry tree varieties. Some of the obvious ones which are of particular interest to gardeners are listed below.
Number of petals
Cherry blossoms have from 5 to more than 300 petals (!) They can be divided into 4 groups based on the number of their petals. Single flowers feature 5 petals and sometimes 1-3 extra petals. Semi-double flowers boast 10-20 petals while double flowers exhibit 25-50 petals. The impressive chrysanthemum flowers are packed with over 100 petals. In Japan, many people would consider these double or chrysanthemum flowers quite gaudy. Their most popular and acclaimed cherry blossom is the Yoshino (Prunus x yedoensis), which has five white petals and is treasured for its delicate, simple form.
The same cultivar may display single flowers with 5 petals on one specimen, but 15 petals per flower on another specimen. Soil fertility may have an impact on these variations as fewer petals tend to be produced in lean soils.
The petals may be oval, egg-shaped, or round. They may be wrinkled, frilled, or display wavy margins.

Color of the blossoms
Most cherry flowers are light pink to white, but there are also cherry trees with dark pink, yellow or green blossoms. Appreciating the color of these lovely blooms is however not always easy because cherry blossoms change color over their life. Many are dark pink when in the bud, lighter pink when they first blossom, and then eventually pale pink or white when fully open. Some cherries, such as 'Shirofugen', see their whole flower color change from white to pink, giving an entirely new look at the end of the flowering season.

Fragrant blossoms
Many Japanese flowering cherries are fragrant and exude a pleasing scent of crushed almonds. Prunus 'Amanogawa' is reported by some as having a freesia fragrance. However, on cold and rainy days, their fragrance is barely perceptible, except for strongly scented cherries such as 'Amanogawa' or 'Jo-nioi'. The Japanese word 'nioi' means fragrance and is often added to the cultivar name.
Blooming Season
Most cherry tree varieties bloom in spring over a season that usually lasts several weeks. However, changes in weather conditions may have an impact on the time of flowering, advancing or delaying the appearance of the beloved cherry blossoms by several weeks. Generally, the milder the climate, the earlier the blossoms open.
Spring as a season can be short and last only 3 weeks, as in Japan. In moderate climate areas, such as Britain or the Netherlands, spring may last 6 weeks or even more.
The cherry blossom season is relatively short. There may be 2 or 3 weeks between the opening of the first blossom and the shedding of the petals. Generally, the double flowers last longer than the single ones. Strong wind and rain can reduce the blooming season even shorter.
Not all cherry trees bloom at the same time. There are early bloomers such as Prunus pendula 'Pendula Rosea' and Prunus x yedoensis (Yoshino cherry). They are followed by garden cherries, including the lovely Prunus 'Accolade', the deep pink Prunus pendula 'Pendula Rosea', and pure white Prunus 'Umineko'. Closing the spring season is the incredibly popular Prunus 'Kanzan' or Prunus 'Shogetsu'.
Some Cherry tree varieties enjoy a particularly long blooming season and flower in flushes in the fall and during the winter months. Among them are Prunus subhirtella 'Autumnalis Rosea' (Rosebud Cherry) and Prunus subhirtella 'Autumnalis'.

Cherry Tree Leaves
Although ornamental cherry trees are typically planted for the majestic yet delicate beauty of their flowers, many varieties are noted for their lovely foliage and multi-season interest. Some display wonderful fall colors, with their foliage turning brilliant shades of gold, red, or orange.
Usually, the foliage unfolds in the spring, either before the flowers, at the same time, or after the blossoms open. In the case of early blooming cherry varieties, the new leaves appear only after the blossoms wane, which creates a spectacular look with thousands of showy pink-white blossoms smothering the bare branches - a sight to behold. In the case of later blooming cherry varieties, the leaves usually appear before the blossoms, giving the trees a very different look.
The color of the new leaves differs between cherry varieties. In most cases, the fresh leaves are green with a bronze hue. They generally mature to dark green and create a lovely summer canopy. Some cherry varieties display wonderful fall color, with their foliage turning brilliant shades of gold, red, or orange, before shedding to the ground.

Cherry Tree Shapes
Japanese flowering cherries enjoy graceful shapes that command attention and create beautiful features in winter. There are 5 types of tree shapes and habits:
- Fastigiate or columnar shape with an erect, narrow crown (Prunus 'Amanogawa').
- Broad and ovate
- Funnel shape or vase-like (Prunus 'Kanzan'), becoming very broad over time (Prunus 'Ichiyo')
- Umbrella shape with a very broad and flattened crown. The limbs are thick and horizontal (Prunus 'Shirotae')
- Weeping shape with frothy curtains of pink or white blossoms. Their slender and flexible branches lead them to gracefully weep, sometimes almost kissing the ground. Swaying in the wind, their cascading branches form an umbrella that everyone would want to stand under (Prunus 'Kiku-shidare-zakura').

Growing Flowering Cherries
Flowering cherry trees do well in most residential gardens because their care requirements are minimal. They are not demanding regarding soil type or pH requirements but should be watered thoroughly after planting and until the tree is well-established. Like all cherry trees, ornamental flowering cherries are susceptible to insect and fungal disease problems. Regular pruning to thin out branches and allow for better air and light circulation will help keep your tree healthy. The best time to prune is just after spring flowering. Many fungal diseases can be treated by the application of a fungicide. Signs of diseases include powdery mildew, hard knots or swelling on branches, leaf spots, and discolored or wilted leaves.
- Performs best in full sun in moist, relatively fertile, well-drained soils.
- Prune in midsummer if the silver leaf is a problem
- Watch for caterpillars, leaf-mining moths, bullfinches, silver leaf, bacterial canker, and blossom wilt.
- Propagate by budding or grafting, although softwood cuttings in early summer with bottom heat can be successful.
