　In early summer, hydrangea, which is widely known as a symbolic flower during the rainy season, has become a season to entertain the eyes here and there in the city.　　Hydrangea planted beside the stone wall (Ran Tateran Jun) on the precincts of Tsukiji Honganji Temple is also beginning to bloom.　　　　　　　　　　　　　　　　　　　Hydrangea is often referred to as ancestor in bigleaf hydrangea, which grows naturally in Japan, and is often referred to as "hydrangea" as an idiot in kanji. It is also known as "Hachisen Hana" and "Seven Change", "Yohira" derived from four ornamental flower sepals, and "Temarika" derived from spherical inflorescence.　　　　　　　　In general, hydrangeas, the "ornamental flower" (neutral flower) of petals-shaped sepals cover the "true flower" (bisexual flower) in the center, but there are many varieties that have been crossed and improved, and the "forehead bloom" blooms as if ornamental flower surrounds the true flowers, and ornamental flowerdouble-floweredornamental flower blooms in a densely populated inflorescence.　　　　　　　　A large number of horticultural varieties are produced in the Japanese hydrangea, which has been improved in Europe and the United States (also known as Hydrangea).　　Hydrangea flower color is said to have a lot of aluminum melts out due to the increase in the acidity of the soil, and when absorbed, the flower color is strong blue, and vice versa, the pink is strong, and other fertilizer elements are also affected. It seems to be known. In addition, there seem to be various theories about the etymology of hydrangea, but I hear that the theory of "the meaning of Shu (Atsu) Shin (Sa) Ai (Ai)" is considered to be influential.
