What characterizes a tiered arrangement in floral design?

A tiered arrangement in floral design is characterized by flowers being placed at various heights. This design technique creates visual interest and dimension, allowing for a dynamic presentation of flowers. By using different heights, floral designers can showcase the beauty of individual blooms and provide a more engaging composition. This arrangement draws the eye upward and provides depth, often resembling layers, which can enhance the overall aesthetic appeal of the arrangement.

The other options do not accurately describe a tiered arrangement. Flat arrangements involve flowers being positioned at the same height, which contrasts sharply with the tiered approach. Using a single type of flower would limit the variety and dynamics that height variations can bring to the arrangement, thus straying from the tiered concept. Finally, a focus primarily on filler flowers would typically lead to a less prominent presentation, diverging from the intention of showcasing a variety of blooms at different heights.
