What is a key role of "Filler Flowers" in an arrangement?

Filler flowers serve an essential function in floral arrangements by adding texture and bridging gaps between larger flowers, thus filling empty spaces within the design. They contribute to the overall aesthetic by softening the arrangement and providing depth without drawing attention away from the focal points. Their varied shapes, sizes, and colors complement the primary flowers, enhancing the visual appeal and ensuring the arrangement looks balanced and complete.

While primary focus and color domination are generally the roles of main flowers, and structure and form are often provided by line flowers, filler flowers specifically target the enhancement of texture and the harmonious filling of gaps, which is crucial for creating a cohesive floral design.
