Indoor bonsai are bonsai cultivated for the indoor environment. Traditionally, bonsai are temperate climate trees grown outdoors in containers.[1] Tropical and sub-tropical tree species can be cultivated to grow and thrive indoors, with some suited to bonsai aesthetics shaped as traditional outdoor or wild bonsai.[2][3]
Bonsai and related practices, like penjing, hòn non bộ, and saikei, involve the long-term cultivation of small trees and landscapes in containers.[1][2] The term bonsai is generally used in English as an umbrella term for all miniature trees in containers or pots.[2]
