Bonsai is a Japanese Art in the cultivation of miniature.
The word “Bon-sai” (often misspelled as bonzai or banzai) is a Japanese term which, literally translated, means “planted in a container”. This art form is derived from an ancient Chinese horticultural practice, part of which was then redeveloped under the influence of Japanese Zen Buddhism.

It has been around for well over a thousand years. The ultimate goal of growing a Bonsai is to create a miniaturized but realistic representation of nature in the form of a tree. Bonsai are not genetically dwarfed plants, in fact, any tree species can be used to grow one.
It's a very beautiful & wonderful art.
