Bonsai Styles Double trunk: Double trunk(Sokan)
The double-trunk style, also called mother-child, represents two similar subjects, with the same pattern, with the base in the same point. Ideally the two trunks should belong to the same plant, they should therefore grow from the same roots, but frequently one arrives at a double-trunk bonsai starting from two specimens, generally of slightly different dimensions, but with similar handles and sinuosities.
This style is quite often found in nature; for this style generally coniferous trees are used, but also deciduous trees are suitable. It is possible to use the sokan style in combination with other styles, so for example you can prepare bonsai with a double trunk beaten by the wind, or a double trunk in cascade.
Generally the main trunk develops quite erectly, while the smaller one, which must develop from the base of the other, tends to be slightly prostrate; the ramifications must be harmonic, so that interlacements between the branches of the two plants do not occur. A variant of this style is the Sankan style, with three trunks, with a larger trunk and two small trunks, which divide from the "mother" trunk at the base of the plant.
