Japanese bonsai are more expensive than regular plants because of their artistic and cultural value, which not only involves careful pruning and cultivation processes, but also involves choosing the right pot and maintenance techniques. The price of bonsai is affected by multiple factors such as the age of the tree, the rarity of the tree species, the artistic shape, the quality of the pot and the historical background. These factors jointly determine the market value and collection value of bonsai, making it not only a plant, but also a living work of art.
