I'm not crazy about the round pot suggestion, tbh. Someone a while ago mentioned to me that rotationally symmetrical (round, square, hexagon, lotus, etc) pots work best with strongly asymmetrical trees, and it's stuck with me ever since. Even if you give it the leftward tilt, the visual mass of the second trunk is visually balanced by the right branch.
I'm probably just being too much of a stick in the mud though!
Interesting comment, allows the tree to speak for itself. Goes along with the pot's primary role to complement the tree.
When I consider the chosen pot above, this is what I see.
angular with soft corners, soft colour, shallow rectangle, basically straight lines.
One of the best authors for discussion of container selection is David DeGroot. My favourite section is found in his most recent book Principles of Bonsai Design.
A couple of passages for consideration.
Match the character of the tree with the character of the container.
Remember masculine and feminine characteristics are not mutually exclusive.
The tree above has slender trunks and more graceful or elegant appearance. two trunks similar in size from the same base.
A masculine tree with an elegant form is recommended to have a pot with a slim profile, restrained decoration, primarily straight lines.
A feminine tree with a graceful form is recommended to have a regular form with smooth textured surface and glazes.
The character of the tree above is both feminine and masculine. movement is more angular than rounded, bark is rougher than smooth, overall form is slender rather than strong footage or powerful base.
The softer and smoother rectangle is a good fit in this particular circumstance in my view for all of the above.
For those interested in container selection, two of the best written discussions I have encountered are within Techniques 11 by John Naka and Principle of Bonsai Design by David DeGroot. either edition of the latest book. published 2022 second edition, available through Stone Lantern.
