What is the main focus of a cascading floral arrangement?

The main focus of a cascading floral arrangement is to create a waterfall effect. This type of design typically features materials that are intentionally arranged to flow downwards, mimicking the appearance of water cascading down. In a well-executed cascading arrangement, flowers and foliage are chosen and positioned in such a way that they interact with gravity, allowing the eye to follow the lines of the design as they move downward. This technique is often used in bridal bouquets, where the cascading effect adds elegance and drama.

The other options do not accurately represent the defining characteristic of cascading arrangements. For instance, maintaining a compact structure would align more with arrangements like bouquets or centerpieces that emphasize neatness rather than movement. Emphasizing height could refer to vertical designs such as those seen in tall centerpieces, which contrast with the horizontal flow of a cascading style. Lastly, using only round blooms does not pertain to the cascading style; rather, this could describe arrangements that focus on symmetry and uniformity. Cascading designs benefit from a mix of shapes and forms to enhance the flowing effect that is central to their appeal.
