Which term describes the geometric shape or outline of a floral arrangement?

The correct term that describes the geometric shape or outline of a floral arrangement is "form." In floral design, form refers to the overall structure and shape that the flowers and foliage create within the arrangement. This includes how the elements are positioned in relation to each other and the silhouette that they produce.

Different forms can evoke various feelings or themes in the arrangement, such as modern, traditional, or wild. Understanding and manipulating form is essential for creating visually appealing and balanced designs.

Other terms, like color, texture, and volume, play important roles in floral arrangements but refer to different aspects. Color pertains to the hue and saturation of the flowers and how they interact with one another. Texture involves the surface quality of the materials used, such as the smoothness or roughness of petals and leaves. Volume refers to the amount of space the arrangement occupies, which relates more to the size and density rather than the overall shape.
