Hydrangea (Ajisai in Japanese) is a sign of the rainy season in Japan. If Ume (plum blossom) is the sign of early spring, then hydrangea is the symbol of the coming summer. In general, they start blooming from early June to mid-July. During the gloomy rainy season, people in Japan enjoy viewing hydrangea flowers, and hydrangea flowers match rain very well. This year we show you hydrangea flowers in Wakayama castle park. They create beautiful harmony with castle stone walls.
