Bonsai (盆栽?, lit. plantings in tray, from bon, a tray or low-sided pot and sai, a planting or plantings,  pronunciation (help·info))[1] is a Japanese art form using miniature trees grown in containers. Similar practices exist in other cultures, including the Chinese tradition of penjing from which the art originated, and the miniature living landscapes of Vietnamese hòn non bộ. The Japanese tradition dates back over a thousand years, and has its own aesthetics and terminology.

Indoor bonsai are bonsai which are cultivated for the indoor environment. Traditionally, bonsai aretemperate climate trees grown outdoors in containers.[1] Kept in the artificial environment of a home, these trees weaken and die. But a number of tropical and sub-tropical tree species will survive and grow indoors. Some of these are suited to bonsai aesthetics and can be shaped much as traditional outdoor bonsai are.
