What is the primary function of filler flowers in a floral arrangement?

Filler flowers play a crucial role in floral arrangements by providing bulk and volume. Their primary function is to fill in the spaces between larger focal flowers, creating a more balanced and harmonious composition. By incorporating these flowers, the arrangement gains a fuller appearance, which can enhance its overall aesthetic.

In addition, filler flowers can soften the edges of the arrangement and help to unify the various elements, allowing the main blossoms to stand out without overwhelming the viewer. This use of filler flowers is integral in achieving depth and texture, contributing significantly to the visual appeal of the arrangement. They also introduce color contrasts and variations that can complement the focal flowers, enriching the overall design while maintaining their supportive role in the arrangement.
