What term describes the tight positioning of flower clusters at the base of an arrangement forming rounded hills?

The term that describes the tight positioning of flower clusters at the base of an arrangement, forming rounded hills, is known as pillowing. This technique is used to create a fuller and more visually appealing base in floral arrangements, enhancing the overall structure and allowing for a sense of depth and dimension. By grouping flowers closely together and arranging them in a way that resembles small hills or mounds, this technique draws the viewer's eye upward through the arrangement, creating a harmonious balance.

In contrast, ikebana refers to the Japanese art of flower arranging that emphasizes minimalism and the harmony of the arrangement with the surrounding environment. Waterfall design describes a technique where flowers are arranged to mimic the flowing nature of water, showcasing a cascading effect. Abstract designs focus on non-traditional forms and may not adhere to the natural shapes found in floral compositions. Each of these alternatives serves a different purpose in floral design, while pillowing specifically concentrates on achieving a lush, rounded base.
