Yamazakura ( also called Japanese Cherry, Hill Cherry, Oriental Cherry, East Asian Cherry), is a variety of cherry native to Japan, Korea and China and is used for its spring cherry blossom displays and festivals. Blooms are very showy.
This cherry is introduced to the West from Japan in 1914. Unlike other P. serrulata forms, this cherry is not considered a cultivated variety and it can vary greatly, especially in flower color - from white to pale pink. (bbg.org info)
It is a small deciduous tree or shrub with a short single trunk, with a dense crown reaching a height of 26–39 feet (8-12 m). The smooth bark is chestnut-brown, with prominent horizontal lenticels. The leaves are arranged alternately, simple, ovate-lanceolate, 5–13 cm long and 2.5–6.5 cm broad, with a short petiole and a serrate or doubly serrate margin. At the end of autumn, the green leaves turn yellow, red or crimson.
The flowers are produced in racemose clusters of two to five together at nodes on short spurs in spring at the same time as the new leaves appear; they are white to pink, with five petals in the wild type tree. The fruit is a globose black drupe 8–10 mm diameter. (wikipedia info)

|Germination||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 65F (+18C) during the day and 48F (+8C) at night. Or sow indoors in the propagator or pots
4. Prepare a pot for each seed. Fill 8-inch plastic pots with garden soil taken from the bed where the trees will eventually be planted. Sow one seed in each pot at a depth of 1 inch.
5. Water the seeds to a depth of 3 inches after planting them. Maintain moisture at a 3-inch 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 4 inches in height.
8. Plant the seedlings into a sunny, sandy bed at least 75 days before the first frost in autumn, or shelter the seedlings in a cold frame until the following spring if it is too late in the year for planting. (info source: eHow.com)
