Tree-dwarfing art, also known as bonsai (6 letters), is a centuries-old Japanese art form that involves the cultivation of miniature trees in containers. The goal of bonsai is to create a small tree that resembles a full-sized tree in nature. Bonsai trees are grown from regular trees and shrubs, and are trained and pruned to maintain their small size. The art of bonsai requires patience and skill, and can take years to perfect.
