What is a floral ring used for?

A floral ring is specifically designed for creating circular floral arrangements, making it an ideal choice for arrangements such as wreaths. The structure of a floral ring provides a base upon which flowers and other materials can be arranged in a circular format, allowing for a balanced and aesthetically pleasing design. This type of arrangement often highlights the flowers' natural shapes and colors in a way that emphasizes their roundness and can be ideal for seasonal decorations or celebrations.

In contrast, other uses mentioned in the options do not align with the primary function of a floral ring. While centerpieces, support for stems, and preservation techniques are important aspects of floral design, they utilize different tools and methods. Centerpieces typically involve various container types, while support for tall stems would use stakes or specific types of floral foam or grids. Preservation methods usually require different materials and techniques outside the scope of a floral ring's purpose.
