Another common but not exclusive aspect present in "ikebana" is its employment of minimalism. Some arrangements may consist of only a minimal number of blooms interspersed among stalks and leaves. The structure of some Japanese flower arrangements is based on a scalene triangle delineated by three main points, usually twigs, considered in some schools to symbolize heaven, human, and earth, or sun, moon, and earth. Use of these terms is limited to certain schools and is not customary in more traditional schools. A notable exception
