What floral design concept uses a combination of height and depth to create interest in an arrangement?

The concept of layering in floral design involves integrating different heights and depths within an arrangement to create visual interest and complexity. This technique allows for the use of various floral elements, such as taller stems and shorter blooms, which together create a dynamic appearance. Layering can involve the strategic placement of flowers and foliage to produce depth, leading the viewer's eye through the design and providing a sense of movement and richness.

In contrast, contemporary design often focuses on modern aesthetics that may not prioritize traditional layering but rather emphasize bold statements through shapes and forms. A pave arrangement is characterized by a flat, dense surface of flowers with minimal variation in height, which contrasts with the idea of layering to create depth. Minimalist design, while elegant, typically opts for simplicity and fewer elements without the rich textures and dimensions found in layered arrangements. Thus, layering proves to be the correct concept for creating interest through a mix of heights and depths in floral arrangements.
