The tree in the ‘formal upright’ style has straight tapering trunk.
In the informal ‘upright’ the trunk is not straight and the top is bent slightly to the front.
In the ‘slanting style’ the trunk of the tree is slanting and the lowest branch spreads in the opposite direction of the slant with the top slightly bent forward.
The tree trunk in the ‘semi-cascade’ style grows upwards for a short distance and then falls over the side of the pot or container but above its bottom.
The ‘cascade style’ is almost similar to ‘semi-cascade’ except that in this case the tree trunk reaches below the level of the pot.
When all the branches of the tree grow from one side only, as if these were swept by wind, the style is known as ‘wind-swept’.
In the broom style all the branches grow almost from the same place.
The tree is planted on a rock with the roots extending down into the soil or roots are attached or clasped to the rock in the ‘root-over-rock’ and ‘clinging-to-a-rock’ styles.
