The Hydrangea (紫陽花, アジサイ, Ajisai ) is another one of the popular flowers in Japan.
Hydrangeas typically bloom during the rainy season in June ~ July, making them a symbol and the most popular flower of the season.

The colorful flowers are the perfect cure for rainy days of June and July.

The color of hydrangea is largely affected by the pH in the soil.
Acidic soils (which contains aluminum ) will produce blue to purple flowers, while alkaline soils will produce pinks and reds.
