The cherry blossom (sakura) is Japan's unofficial national flower. It has been celebrated for many centuries and takes a very prominent position in Japanese culture. There are many dozens of different cherry tree varieties in Japan, most of which bloom for just a couple of days in Spring. The Japanese celebrate that time of the year with hanami (cherry blossom viewing) parties under the blooming trees.
Indeed, the trees that line the shore of the Tidal Basin in Washington, D.C. were gifts from Japan, launching America's affair with the cherry blossom, and the National Cherry Blossom Festival.
Much like the Apple Blossom, the Cherry Blossom is a soft, sheer floral with a hint of cherry.
