Styles: Twin Trunk - Sokan
Often referred to as the mother and son style, a second smaller trunk grows alongside the main tree. When styling, to give added depth the secondary trunk should ideally be positioned slightly behind and not directly side-by-side to avoid a flat, two-dimensional image.
In classical twin trunks the secondary trunk emerges at the base of the main tree, forming an acute angle. The first major branch normally grows on the smaller trunk.
Pleasing variations can be achieved with the smaller trunk being either short or tall, and not growing from the base, but slightly higher up the tree. Rectangular and oval pots are most suited to this style. Natural trees with two trunks are quite common.
