Which element of design refers to the "feel" of materials used in floral arrangements?

The correct choice emphasizes texture, which is an essential element of design in floral arrangements. Texture refers to the physical surface quality of materials, which can evoke different sensations and emotions. In the context of floral design, texture can range from the smoothness of a rose petal to the roughness of tree bark or the spikiness of thorns. By combining various textures, floral designers create visual interest and depth in their arrangements, making them not only aesthetically pleasing but also engaging to the senses.

In floral arrangements, the interplay of various textures can enhance the overall composition, communicate mood, and even affect how the viewer perceives the arrangement's dimension and complexity. For instance, a combination of soft, delicate flowers paired with sturdy, coarse foliage creates a dynamic contrast that draws attention and invites closer examination. Understanding how to utilize texture effectively separates novice designers from experienced florists.
