What is the purpose of using glycerin in a floral arrangement?

Using glycerin in a floral arrangement serves the purpose of preserving certain foliage. When leaves and other plant parts are treated with glycerin, the solution replaces the water within the plant cells. This process helps to maintain the texture and color of the foliage for an extended period, making it look fresh rather than wilted. The preservation process can help keep the leaves pliable and less prone to drying out or becoming brittle, which is essential for creating long-lasting floral arrangements.

While other options may relate to aspects of floral care, they do not accurately represent the primary function of glycerin in this context. For instance, glycerin does not inherently color flowers or provide them with essential nutrients, nor does it enhance fragrance. These functions are covered by different methods and materials used in floristry.
