Ikebana is the art of arranging flowers aesthetically. One tries to represent the three elements sky, earth, and mankind in a well balanced relation.
Ikebana developed in the 16th century. Traditional Ikebana is called Kado. There are many different schools of traditional Ikebana. In addition, modern styles of Ikebana (avant-garde Ikebana) have evolved. Some of these styles use glass, iron, and other materials instead of flowers.
