Which of the following is NOT an example of floral design forms?

In the context of floral design, forms typically refer to specific shapes or styles that are established in the arrangement of flowers, and each mentioned type falls into commonly recognized categories of floral design. Triangular, round, and vertical forms are all well-defined styles used by floral designers to create visually appealing arrangements.

The triangular form emphasizes height and is often associated with dynamics and movement, while the round form presents a more compact and symmetrical look that is gentle and traditional. The vertical form showcases straight lines and upward growth, conveying a sense of elegance and strength.

However, 'balanced' does not represent a specific floral design form. Instead, balance refers to an overarching principle of design that can be applied to any arrangement to achieve visual harmony. It is more about the distribution of visual weight within the design rather than a standalone shape or form. This distinction clarifies why 'balanced' is not considered an example of floral design forms.
