The optical effect in the design of bonsai
In this chapter we’ll look at the aesthetics of bonsai design. You first need to realise that symmetry stands for ‘man made’ and that a-symmetry symbolises ‘nature’. Trees in nature are not symmetrical, so bonsai should also reflect that in their designs. A bonsai is not an exact copy of a tree in nature. The complexity of nature is simplified, minimised and stylised, resulting in a clear understandable layout of trunk and branches. The principle of simplification has its roots in Zen Buddhism.
Bonsai is a composition in which its trunk and branches play an important role in the expression of a tree. The choice and placement of the branches is made according to a well thought out plan. Open spaces between the branches serve as a tool to create a balanced and dynamic branch setting. For example, parts of the trunk, like a gangling curve or an interesting hollow not concealed by branches, will have open spaces around them. With such open spaces you can highlight certain parts of your bonsai creation.
Here is a twin trunk style Buxus by Alain Arnaud. No branches cover the lower part of the trunk with the beautiful deadwood. The open spaces between the branches create interesting layers of foliage and engender a feeling of depth. Note that the branch setting is not symmetrical, the left and right parts of the tree are quite different.
