Identify an example of a filler flower.

Baby's breath, also known scientifically as Gypsophila, is considered a quintessential filler flower in floral arrangements. Filler flowers are typically smaller, delicate blooms used to fill spaces between larger flowers and add texture and volume to arrangements without overwhelming the composition. Baby's breath is characterized by its tiny white or pink flowers that create a soft, airy feel, making it ideal for both modern and traditional designs.

In contrast, the other options, such as delphinium, lily, and rose, are usually focal points in arrangements due to their larger size and more prominent blooms. These flowers tend to draw the eye and serve as the main attraction in a bouquet, rather than complementing other flowers as a filler does. This is why baby’s breath is the most suitable choice for an example of a filler flower.
