The coiled "Bankan" style of bonsai trees is a distinctive and dramatic style that showcases the resilience and adaptability of the trees. It is characterized by a trunk that has a pronounced S-curve or twist, which gives the tree a sense of drastic movement and tension. The branches are arranged to enhance the S-curve of the trunk and create an interesting yet balanced overall shape. The coiled "Bankan" style is often used for juniper bonsai trees, as they have a strong sprouting ability and can develop deadwood features that add to the visual appeal. This style represents the trunk of a juniper tree that has been curved by prolonged exposure to wind and weather on a cliff or a rocky slope.
