Which of the following is considered a filler flower?

Baby's breath, also known as Gypsophila, is considered a filler flower because it serves the purpose of filling in spaces in floral arrangements. Filler flowers typically have small flowers and a delicate structure, making them ideal for adding texture and fullness without overwhelming the design. They are used to complement the focal flowers, enhance the overall composition, and create a more balanced appearance in arrangements.

In contrast, roses, lilies, and sunflowers are generally classified as focal flowers due to their larger size and more vivid presence in floral designs. These flowers are typically used to draw attention and provide the primary visual impact in an arrangement, rather than to fill in empty spaces.
