　"Yama Hydrangea", which grows on the prosperity beside Bairin in the Hamarikyu Onshi Garden, is at its best.　　　　　　　　　　　　　　　　　Yama hydrangea is a flowering tree that grows naturally mainly on the Pacific side west of Kanto since ancient times.　Compared to bigleaf hydrangea, which is considered to be the hydrangea ancestor, it is also called Kogaku because of its small size, and Sawa Hydrangea because it tends to grow along moist forests and swamps.　　　　　　　　　In addition to gaku blooming, there are also temari blooming, and the small elliptical leaves are thin, glossy, thin branches, and delicate.　　　　　　　　　　Flower color and flower shape are said to have many variations depending on the region.　　　　　　　　I hear that it is rich in wildness, is often used for tea flowers, and many enthusiasts.　　　　　　　　　　　　　　　　　　　　　　　　　　　In the Hamarikyu Onshi Garden, you can enjoy a variety of "ornamental flower" flower colors for each plant, such as cobalt blue, pale blue and pure white.　　　　　　　　　　　　　　　　　　　　　　　　　　　　　By the way, although the etymology of hydrangea is unknown, the appearance of blue flowers gathering together suggests that "Azusa Ai", which means "Azusa Ai", which means "indigo-colored", has been accented. .
