What is the primary use of floral foam?

The primary use of floral foam is to provide support and hydration for fresh flowers in arrangements. This material is designed to absorb water, allowing it to maintain moisture for the cut stems of the flowers, which is crucial for their longevity and freshness. The structure of floral foam supports the arrangement by holding stems securely in place, which helps maintain the desired shape and design of the floral display. This dual function of hydration and support is essential for ensuring that the flowers remain viable and aesthetically pleasing for an extended period.

Other options, while they may touch on certain aspects of floral arrangements, do not accurately capture the primary function of floral foam. Enhancing visual appeal or creating fragrance are secondary benefits that can arise from the use of floral foam in a design, but they are not its main purpose. Similarly, while pest control is important in floral design, it is not a role that floral foam plays. The foam's main contribution rests firmly in providing both hydration and structural support to the arrangement.
