What effect do mass flowers have on a floral arrangement?

Mass flowers primarily contribute visual weight to a floral arrangement due to their dense and large blooms. When included in a design, these flowers serve to anchor the composition, providing a focal point that draws the eye. This visual weight can enhance the overall balance of the arrangement, making it appear more substantial and grounded.

In contrast, while height and lightness, softening edges, and introducing bold colors are important aspects of floral design, they are not the primary effect created by mass flowers. Height and lightness are generally associated with line flowers or fillers that have a more airy and elongated quality. Softening edges typically relates to the use of foliage or softer, smaller blooms that can help to create a more organic feel. Bold colors can indeed be introduced through mass flowers, but the defining characteristic of mass flowers is their ability to bring a sense of weight and stability to the arrangement. Therefore, the essence of mass flowers is best captured by their role in creating visual weight.
