In Japan, cherry blossoms begin in April, when children return to school after spring break and adults return to work. Japan's National Weather Service even monitors the so-called "sakura front" - an imaginary line that runs from south to north each season and marks the flowering of these magnificent trees. Sakura is associated with the ancient Japanese tradition of hanami, or having picnics under the shade of cherry blossoms. Sakura is found in both China and Korea, but nowhere does it have such a deep cultural meaning as in the Land of the Rising Sun. And although it is best to enjoy the view of cherry blossoms against the backdrop of a Japanese castle, mountain or imperial garden, you can grow this plant even in your city.
