I live in Hiratsuka-city near Yokohama. Japan, which belongs to a Temperate Zone, monsoon climate area. We have moist, hot summers where it is 30 degrees C, usually for 7 weeks. We have cool winters where it is zero degrees C, for 6 weeks. With lots of rain and a warm climate, plants grow well.
Japan is mountainous, with little amounts of field areas.
Therefore, as you may know, each Japanese garden is so small. But if I will take drive for 5 minutes by a car, I can arrive at a paddy field. It is a treasury of wild grass. I am happy that if I can introduce the prettiness of these flowers in pictures for you. I've taken a wildflower pictures for over 25 years.
