Classic Formal Broom Chinese Elm by Harry Harrington
Formal Broom Form

The best known broom form has a main trunk that divides at a certain point
into three or more branches of roughly equal thickness which grow out
diagonally upwards from the central trunk.
The silhouette of the tree resembles an upturned Japanese broom; hence the
name.
The main trunk of the formal broom tends to be 1/3 of the overall height of
the bonsai. There are no horizontal branches; all branching is placed diagonally
in a fan-shape with no, or very few, crossing branches.
There are variations of the classic formal broom; there can be a main trunk
that runs from base to apex of the tree. However, unlike a (in)formal upright, the
branches are nearly as thick and dominant as the central trunk, but all of these
branches are placed at upturned diagonals from the main trunk, forming a broom

silhouette.
