Hakone - Hydrangea Train

Hydrangea bush in the foreground with a blurred background of a red train coming towards the viewer.

From the end of May to the rainy season in June, hydrangeas are at their best in Japan. The name "Ajisai", hydrangea in Japanese, is said to come from "Azusa Ai" which means a gathering of indigo. Due to this, there are speculations that when the plant was first discovered and named in Japan, they were all blue hydrangeas. Research found that hydrangea becomes more bluish in acidic soil compared to it becoming more red in alkaline soil.

We can speculate that most of the soil in Japan is quite acidic, whereas in Europe, they have more alkaline soil.  

Hydrangea looks like a cluster of small flowers that is large and round, but the big petal-like parts are actually not part of the flower. The large round petals are actually developed pieces of the stem, and if you look closely, you can see a very small flower of hydrangea in the middle of the cluster.

Events recommended for those who are interested in Japanese hydrangea are going to be coming around this June. It might be worth visiting some of these if you are in Japan during this season!
