What is a key characteristic of a filler flower?

A key characteristic of a filler flower is its ability to enhance texture and volume in a floral arrangement. Filler flowers are used to occupy space and add depth to the design without overpowering the primary focal flowers. They contribute to the overall aesthetic by filling in gaps and providing a lush and full appearance, which can make the bouquet or arrangement more visually appealing.

By incorporating these flowers, designers can create a more cohesive and balanced look, ensuring that the arrangement looks complete while highlighting the main features. This role is distinct from other characteristics like providing shape, creating focal points, or defining lines, which are more specific to different types of flowers or design elements.
