An Ichinoeda is a type of Chinese Penjing that consists of a single tree planted in a shallow container. The word Ichinoeda means "one branch" in Japanese, and it refers to the style of pruning the tree to have only one main branch. This creates a simple and elegant appearance that contrasts with the complex and naturalistic Penjing landscapes that often include rocks, water, and figurines .
Ichinoeda is used for bonsai to create a minimalist and refined aesthetic that focuses on the shape and movement of the trunk and branch. It is also a way to showcase the beauty of the tree species, such as the Chinese elm, which has small leaves, fine ramification, and attractive bark . Ichinoeda can be displayed as a single specimen or as part of a group planting.
