What is the term for a line of demarcation that creates visual interest in a landscape?

The term that refers to a line of demarcation creating visual interest in a landscape is "edging." Edging typically involves defining spaces within a landscape design, such as separating different areas, like flower beds from lawn or pathways from garden spaces. This division draws the eye and enhances the overall aesthetic appeal of the landscape by providing structure and organization.

Edging can also enhance the formality or informality of a space, depending on the materials and techniques used. It can provide texture and contrast, making the landscape more engaging and harmonious. The practice of incorporating edging elements contributes not only to the organization of planting areas but also to the functionality of the landscape by directing foot traffic and guiding movement.

Understanding the role of edging in landscape design emphasizes its importance in creating visually compelling environments, which is why it is recognized as a key aspect in architectural theory and landscape design discussions.
