Hydrangea (sientific name:Hydrangea macrophilla) is native to Japan and is a cold-resistant deciduous shrub of the family Hydrangeae family. The original species is Hydrangea macrophylla (Gaku-ajisai, H. macrophylla f. Normalis), decorative flowers border around amphibian flowers. Hydrangea is a varietal kind of hydrangea, which consists almost of decorative flowers, and a large hemispheric flower (hand-ball type as seen from above) blooms when a large number of sepals appear like flowers. Flowers are made of two kinds of bisexual flowers (complete flowers = reproductive ability) and decorative flowers (incomplete flowers, neutral flowers). What is conspicuous is the decorative flower, which is made of large calyxes and looks like four valve flowers. Decorative flowers (actually calyx) can not produce fruit because stamens and stamens are degenerate. Bisexual flowers have stamens and stamens, but they are inconspicuous because they are extremely small blue five-flower flowers. It is a valuable flower because it blooms at the rainy season when other flowers do not bloom. calyx color changes depending on climate, soil quality, and time. With the passage of time, even the same flower (calyx), discoloration changes from light green to white to blue, pink and white. Various hydrangea garden cultivars such as Sumida fireworks, circus, sword dance, kaleidoscope etc. are breeded. Yamazadai (mountain hydrangea, scientific name: Hydrangea serrata) is distributed in mountainous areas and becomes a raw material for sweet tea. The tree height is lower than the hydrangea, the leaves are small, and the flower color is many. There is a great rainbow in mountain hydrangea variety. Hydrangea (hydrangea hydrangea, scientific name: Hydrangea serrata var. Megacarpa) is a variant of mountain hydrangea growing naturally in the multi snowy area of Hokkaido and the Japan Sea side, larger than the mountain hydrangea. Hydrangea (Western hydrangea) is a Japanese hydrangea that has been bred to Europe and has Temari type and Gakuchibuchi type. Kashiwaba hydrangea (Kashiwaba Hydrangea) is a flower blooming closer to Buddleja (Japanese name: Fusa Fujiyugi) than Hydrangea.
