Which type of flower is often used to fill in arrangements and provides a delicate effect?

Filler flowers are specifically used in floral arrangements to enhance the overall appearance and add depth without overwhelming the main focal points of the design. They are characterized by their delicate and often lighter features, which effectively fill in spaces and create a sense of balance and harmony within the arrangement.

Filler flowers typically have small blooms and can come in a variety of colors, allowing them to complement and contrast with other flower types, enhancing the visual appeal of the arrangement. Their role is crucial in ensuring that the arrangement looks complete while maintaining a soft and airy feel.

In contrast, form flowers are designed to be the focal point of arrangements due to their unique shapes, mass flowers are bolder and thicker, primarily used to create fullness, and line flowers are structured to draw the eye upward and create height within a design. These characteristics differentiate filler flowers from the other types, making them ideal for achieving that delicate effect sought in floral design.
