The “Kengai” or “Cascade” style is inspired by trees that grow in the wild on rocky walls and are bent downwards as a consequence of different factors, such as snow falling or rockslides. With bonsai, it can be difficult to maintain the growth downwards as the natural tendency for the trunk would be to go upwards. These bonsai are often planted in high pots with the apex falling below the base. Branches grow in either direction, horizontally, to maintain the balance of the tree.
