About

Somei Yoshino is a variety that represents Japan’s cherry blossoms, and is said to occupy 80% of the whole. It is a flower that symbolizes Japan, but it is not a native species since ancient times, but a horticultural species, and many of them are planted in various parts of the country during the period of high economic growth (1954-1973). All of them are clones grown by grafting from one tree. Therefore, every spring, it blooms simultaneously at the same time. In addition, because it is a clone, it will be transmitted to other trees when a single disease suffers from a disease without resistance. This infection has been confirmed in various parts of Japan, and measures are urgently needed.
Although not well known in Japan, it looks just like an almond flower.

ソメイヨシノは日本の桜を代表する一種で、全体の八割を占めると言われている。
日本を象徴する花であるが、古来よりの自生種ではなく園芸種であり、その多くは高度経済成長期(1954-1973)に全国各地で植樹されたものである。そのすべては一本の木から接ぎ木で増えたクローンである故、毎春同時期に一斉に開花する。また同上の理由から、耐性の無い病気に一本が羅漢すると他の木へと伝染していく。日本各地でこの伝染が確認されていて、対策が急務となっている。
