Sakura (Cherry Blossoms):
One of the most popular and omnipresent breeds of cherry blossoms in Japan is "Somei-Yoshino."
But, the description about Somei-Yoshino in Wikipedia is not crucially correct, as is usual in English Wikipedia regarding Japan.
----------
Prunus × yedoensis (Yoshino Cherry; Japanese: ζδΊει Somei-yoshino) is a hybrid cherry of unknown origin, probably between Prunus speciosa and Prunus subhirtella. It occurs as a natural hybrid in Japan, where it has also long been cultivated in Yoshino (after which it is named) and elsewhere; it is now one of the most popular and widely planted cultivated flowering cherries (sakura) in temperate climates worldwide.

----------
This cherry blossom was created through efforts by some nurserymen and gardeners to mate a certain type of sakura with another (actually, P. pendula Maxim. f. ascendens [Makino] Ohwi. vs. P. lannesiana var. speciosa). These craftsmen lived in a village called Somei in Edo (Tokyo) around 1860's including the era of samurai. They sold this breed of sakura under the brand of "Yoshino" which is a name of the mountain area in the south of Kyoto and Nara. Yoshino has been famous for wild cherry blossoms unique to Japan, called "Yamazakura (P. jamasakura Sieb. et Zucc.)."
However, around 1900, Baron Yoshio Tanaka realized some difference between the Yamazakura from Somei Village and ordinary Yamazakura of the Yoshino origin. So, the baron ordered scientist Kimei Fujino to look into cherry blossoms in the notable Ueno Park, Tokyo, where the "Yoshino" sakura in question were also planted. Fujino discovered that the "Yoshino" was actually a unique type, so that he named the breed "Somei-Yoshino" as it had been from Somei Village.

The Somei-Yoshino cherry blossom can be only multiplied through grafting. This breed cannot be mated among itself. Seeds from mating of Somei-Yoshino themselves never come out to grow. Accordingly, billions of Somei-Yoshino trees ever created are all clones from one original tree having been grown by some villagers in Tokyo around 1860's. The Somei-Yoshino sakura can live only for 50 to 60 years.
Cherry blossoms are widely observed in the north hemisphere. But, the types of sakura who beautifully flower are mainly found in Asia, including Tibet. Yet, the center of flowering cherry blossoms' native habitats is Japan. Accordingly, educated people in the world associate cherry blossoms who can flower with Japan, since cherry blossoms in Japan are called sakura.

And, "Somei-Yoshino" is the most popular and omnipresent breed of cherry blossoms in Japan since its start of modernization and industrialization in 1868, for "Somei-Yoshino" was created in Tokyo in 1860's.
It has still some mystery as you know, since only the last samurais could see this breed while their era was going to end...
