hydrangeas(Japanese name:ajisai)

I went to my granpa & granma's house last Saturday.
This flower's photo was taken near theirs house by me.
Because they were very lovely, I enjoyed looking at them!!

〜Do you know?〜
This flower can use as a litmus paper.
Red hydrangeas show acidity.
Blue hydrangeas show alkalinity.
So, the reaction is same litmus paper and Ajisai!
