Hydrangea

Japan is in the middle of a rainy season (Tsuyu).
Tsuyu can span from May to July, but this year it started earlier this week for Tokyo.

Just like the cherry blossom in early spring time, faint colors of purple, blue and white of hydrangea are abundant right now.
It is called "Ajisai" in Japanese and the name in chinese characters is 紫陽花 - "purple sun flower."
The name is very appropriate for walking outside in the wet and cold rain, they really cheer us up with their presense.
