Which technique is often used to create depth in floral arrangements?

Layering or tiering is an effective technique used in floral arrangements to create depth and visual interest. This method involves arranging flowers at varying heights and levels, which helps to lead the viewer's eye through the arrangement. By placing taller elements in the back or center and gradually incorporating shorter blooms in the front, the arrangement achieves a three-dimensional effect. This approach not only enhances depth but also ensures that the composition feels balanced and harmonious.

Other techniques, while they may serve different purposes, do not emphasize depth in the same way. Stacking generally refers to placing items directly on top of one another, which can create verticality but might not effectively showcase variety in depth. Bundling involves grouping flowers together, which can create volume but typically lacks the layered visual effect that depth requires. Framing focuses on outlining or highlighting certain aspects of the arrangement, but it doesn't inherently provide the layered perspective that enhances depth. Thus, layering or tiering is the most suitable choice for achieving depth in floral design.
