It become full bloom at end of April in Japan.
Hanamizuki is called dogwood in English.
About 100 years ago, Japan gave Sakura to America.
And then, America gave Hanamizuki to Japan.
So Hanamizuki is American flower.
Yesterday, I found it.
I was suprised, it is reason that I have been thinking hanamizuki of japanese flower.
I had mistook.
I found a plan what American may give Hanamizuki to Japan again this year.
