Prunus serrulata or Japanese Cherry;[1] also called Hill Cherry, Oriental Cherry or East Asian Cherry, is a species of cherry native to Japan, Korea and China and is used for its spring cherry blossom displays and festivals. 

Prunus serrulata is a small deciduous tree with a short single trunk, with a dense crown reaching a height of 26–39 feet (7.9–11.9 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.
Prunus serrulata is widely grown as a flowering ornamental tree, both in its native countries and throughout the temperate regions of the world. Numerous cultivars have been selected, many of them with double flowers with the stamens replaced by additional petals.
In cultivation in Europe and North America, it is usually grafted on to Prunus avium roots; the cultivated forms rarely bear fruit. It is viewed as part of the Japanese custom of Hanami.

Rosaceae Week : Japanische Blütenkirsche (Prunus serrulata) from my garden in Ritterhude: here are some fotos of Zierkirche/Japanische Blï¿œtenkirsche (Prunus serrulata) from my garden in Ritterhude. Fotos taken in last years during the whole year. In spring with the flowers and in autumn with the leaves the tree looks colorful. I have to clean the foreyard several times in the year, when the flowers, the leaves fall down. That is not so enjoyable.

Really nice presentation


poor trees did not know they would make the humans work so hard…
they designed these falls for their own well being… mulch (leaves) and Leaf mold ( rotting leaves would be ready  next years’) and phosphorous source in soil (flower petals dropping and rotting) …

poor tree, think of it.. all that civilzation deprived it of the year round nutrition and mulching????

Prunus sp. from California. : 4 posts by 2 authors. Attachments (5).
I have been observing this tree every time I visit California.
This looks to me as Prunus serrulata (Rosaceae). Please validate.
About 5 meter tree
Grey bark with horizontal lines.
Leaves with serrate edges. Alternate simple. Petiolar glands can be observed along with lenticels on the stem. Summer may not be the classical flowering season but luckily I could spot few flowers which gave me the lead to ID


Yes … It was flowering more prominently last month, I also photographed it last week.

Must be great to observe when the tree is leafless and in full bloom.


Another picture with fruit
