A sunflower came to just meet a visitor at the entrance of my oku. Because it is called a Western sunflower well, I thought that there is a thing native to Japan, but after checking it in WEB, in the place of origin of the sunflower, the western part of North American Continent is it. It is a beginning in the 16th century that a Spaniard takes the kind home with him/her after New World discovery at home and brought up. It seems to be the biography wa P tanohasarani 17th century in Japan. Then I am said to be it, but it seems to be well only the young time when the growth is prosperous when the sunflower turns around so that a flower presses you with solar movement. It is Echinops ritro that a sunflower is arranged around in Maine. Because a leaf resembles a thistle, it seems to be named.
