'Bonsai' is Japanese for ‘tree in pot’, but the art of bonsai originated in China. As far back as several centuries B.C., China's affluent and well-to-do were already greatly infatuated with bonsais. In the 12th century A.D., the first bonsais were exported to Japan, where the art form was developed further. At the 1862 World Expo in London, Japan introduced the bonsai and kindled Europe's interest in these extraordinary little trees.
