In landscape design, creating interest and avoiding monotony are key goals. While elements like form, line, and pattern are important components, variety is often considered a critical factor for a successful and engaging design.
While form, line, and pattern are fundamental design tools, they are often manipulated *through* variety to achieve the desired aesthetic and functional outcomes. The strategic introduction of differences (variety) is crucial for making a landscape truly captivating and preventing visual boredom.
