Ajisai

Ajisai(hydrangea) is the flower which is the symbol of Tsu-yu in Japan.
I took this picture from the platform of the railway station of my hometown.
I don't like Tsu-yu, but I like this flower.

It becomes blue, purple, red, green, and white. So people say it as "rainbow flower".

BTW, Ajisai is one of the symbol of Tsu-yu.
And also snail is one the symbol of Tsu-yu.
If you find these symbols on Films/Animes/Mangas..., it means it's a June or July. Of course, Sakura means April.
