What role do filler flowers play in floral design?

Filler flowers are essential in floral design for their ability to fill in gaps and add texture to arrangements. Their primary function is to enhance the overall look of a bouquet or floral piece by providing visual interest and supporting the main flowers. Filler flowers often have a lighter, more delicate appearance, which helps to create balance within the arrangement, preventing it from appearing too top-heavy or sparse.

By incorporating these flowers, designers can achieve a fuller, more natural look, while also guiding the eye through the composition. They may also contribute subtle colors and harmonizing elements, enhancing the depth of the arrangement without overpowering the focal flowers.

The other options highlight distinct characteristics that do not align with the purpose of filler flowers. The main focal point of an arrangement is typically represented by larger, more visually striking flowers, while the largest flowers would be the focal or statement pieces rather than fillers. Additionally, while some flowers may have a pleasant scent, it is not a primary role of fillers in floral design. Their utility lies in their structural and aesthetic contributions.
