Flowers such as baby's breath or aster are commonly referred to as what type of flowers in floral arrangements?

Baby's breath and aster are typically categorized as filler flowers in floral arrangements. Filler flowers are used to add texture and fill in the spaces between more prominent elements in a bouquet or arrangement. They complement focal and mass flowers by providing a lush backdrop, helping to create a balanced composition without taking attention away from the main floral features. Filler flowers often have a lighter presence, allowing them to enhance the visual appeal of the arrangement by softening edges and adding depth.

In contrast, focal flowers are the standout, eye-catching blooms that attract attention, while mass flowers are larger and used to create a solid shape within the arrangement. Line flowers, on the other hand, provide structure and shape, guiding the eye through the arrangement. Understanding these classifications helps in designing well-balanced floral compositions.
