　rose of sharon is a deciduous shrub of the family Aoiaceae, native to East Asia, and is a national flower of Korea. It is a flower tree that colors the midsummer well suited to the summer sky, similar to the representative hibiscus of tropical flowers.　　　　　　　　　　　　　　　Regarding the origin of the name of rose of sharon, it is said that the Korean name Mukunfa or the Chinese name Mugen was distorted.　　　　　There are many species that are vulnerable to cold, such as hibiscus, but they are resistant to cold, withstand strong pruning, and easy to cut, so they are considered to be flower trees that are easy to grow as garden trees and hedges. We often see rose of sharon, which has a single reddish purple flower and a deep red petal bottom, but has a wide variety of white, red, pink, reddish purple, compound color and flower color, with a single bloom, semi-double-flowered, double-flowered and flower shape.　　　double-flowered also has a wide variety of varieties, including turbulent, chrysanthemum, and ball.　　A flower stamen (Kazui) protrudes in the center of the corolla, the pillar is split five, and a large number of stamens are connected to the flower column in a cylindrical shape. It is counted as a so-called "one-day flower", and it is said that it will wither in almost one day after flowering, and the life of each flower is short, but it has a lot of buds and continues to bloom for a relatively long time.　　　　　　　　　　　　　　　　　　　　　　　　　　　　The ephemerality that withering in one day leads to the tea ceremony's "apology loneliness" and "once-in-a-lifetime encounter", and in particular, the white single flower and the bottom red rose of sharon seems to have been established as a flower that decorates the summer tea ceremony by the 3rd generation Sotan Senno.　　The white single large rose of sharon planted on the Sumida River Terrace of Tsukuda Park is blooming and shines in the blue sky and gives a cool impression.
