I don’t know the name of tree in English but according to Wikipedia, it says ” Empress tree”.. It’s called ” Kiri 桐 ” in Japanese.
Every late spring, it shows beautiful flower .. The tree is as great material in Japan. But people don’t know how the tree has beautiful purple flower.
Even I didn’t know how the flower was like, until I found this. It’s so beautiful, isn’t it? Yes , it’s like “foxglove ” .
