The Japanese white flowering cherry embodies the romanticism of the ornamental cherry tree that gloriously decorates the spring landscape. A short-lived, large deciduous tree that unfortunately is plagued by many viral diseases, it is native to Japan, Korea and China. Much smaller cultivars of this species is usually found growing in gardens all across the temperate world. This tree becomes V-shaped to rounded in its mature habit.
When in dormancy, the shiny gray-brown bark reflects light beautifully, attaining even a mauve coloring in between the horizontal rows of lenticels (bark pores). In mid-spring, the barren branches are lined with white flower buds that then open to fully cloak the canopy. Blossoms can be single or double (extra pedaled) and later lead to sparse production of small blackish-purple fruits, which usually do not form in its select cultivars. Foliage emerges with a shiny bronze-green hue as the flowering show wanes, and the shiny dark green leaves are lovely ovals with a long tapering tip. In autumn they turn orange-red with hints of gold or bronze.
Grow Japanese flowering cherry in full or partial sun exposures in a fertile, well-draining soil that is moist from spring to autumn. Highly alkaline soils are not ideal. Pruning of branches should be done after the flowering display. Many viruses can inflict the Japanese flowering cherry and thus makes it live no more than fifteen to twenty years. It is stunning as an accent tree in a lawn or along a boulevard as a specimen or formalized row. (Info source: learn2grow.com)

1. Soak the seeds in a bowl of cool water overnight. Lay the seeds on a flat surface to dry for several hours.
2. Stratify seeds in a plastic bag full of moist sand inside the refrigerator for 90 days. Keep the sand barely moist during the cold stratification period.
3. Sow the seeds the following spring once outdoor temperatures rise above +18C (65F) during the day and +8C (48F) at night. Or sow indoors in the propagator or pots
4. Prepare a pot for each seed. Fill with clean soil. Sow one seed in each pot at a depth of 2-3 cm (1").
5. Water the seeds to a depth of ~8-10 cm (~3") after planting them. Maintain moisture at this depth during the germination process.
6. Place the pots outdoors in a sheltered spot where they will be exposed to direct sun in the morning and afternoon. Protect the seeds from direct sunlight during the hottest part of the day since the soil will warm too quickly and dry out.
7. Watch for sprouting one month after sowing. Maintain the same light and moisture conditions provided to the seeds during germination until they grow to 10 cm (4") in height. (info source: eHow.com)
