What is the term for floral material that creates an "airy" look to enhance arrangements?

The term for floral material that creates an "airy" look to enhance arrangements is known as filler flower. Filler flowers serve the purpose of filling in gaps and providing texture and depth within a floral design. They typically have smaller, delicate blooms and are often used to complement the primary flowers in an arrangement, allowing for a more balanced and visually appealing composition. This airy appearance contributes to the overall lightness of the arrangement, making it more dynamic and ethereal.

While the other terms such as base flower, accent flower, and highlight flower may refer to specific roles within floral design, they do not convey the same essence of providing lightness or enhancing airiness that is characteristic of filler flowers. Base flowers form the foundation or structure of an arrangement, while accent and highlight flowers are intended to draw attention or emphasize certain areas, rather than creating an airy quality.
