What is a key factor that influences the height of a floral arrangement?

The height of a floral arrangement is primarily influenced by the type of vase used. Vases come in various heights, shapes, and designs, which can dictate how high the flowers will appear when arranged. A tall, slender vase can enhance the verticality of the arrangement and give the illusion of height, while a short, wide vase may result in a more compact appearance.

In contrast, other factors such as the type of flowers or color scheme can affect the overall aesthetic and theme of the arrangement but do not directly dictate how tall or short the arrangement will be. Light fixtures are primarily related to illumination and ambiance rather than the physical structure of the floral design. Therefore, the choice of vase is critical in determining the final height and overall presentation of the arrangement.
