Which of the following best describes a line flower?

A line flower is essential in floral design because it serves to create height and structure within an arrangement. These types of flowers have a long, narrow form that helps to establish the overall shape and framework of the design. By emphasizing verticality, line flowers guide the eye through the composition, adding elegance and a sense of movement. This structural role is crucial in balancing other elements within the arrangement, allowing for a harmonious composition.

In contrast, flowers that serve as the primary visual focus are typically focal flowers, which capture attention due to their size, color, or unique characteristics. Flower varieties that add fullness are known as filler flowers; they provide texture and density, making a design richer without drawing attention away from focal elements. Lastly, flowers that fill gaps within arrangements are also classified as filler flowers, meant to complete the design by covering empty spaces. Each flower type plays a distinct role in floral design, but the defining trait of line flowers is their ability to contribute to height and structural integrity.
