What materials are commonly used in floral mechanics?

The correct choice highlights the essential materials used in floral mechanics, which are crucial for constructing floral arrangements. Floral foam is designed to hold and hydrate cut flowers, providing stability and support within the arrangement. Tape is used to secure stems, create grids on containers, and ensure that the arrangement maintains its structure. Wire serves multiple purposes, such as strengthening delicate stems, adding height and movement to floral designs, and creating intricate structures like corsages or boutonnières. Containers are vital as they not only hold the arrangement but also play an important role in the design aesthetic.

The other options list materials that may be related to floral work but do not fit within the context of floral mechanics. For instance, paint and glass are not typically utilized for the structural support or stability of floral arrangements. Soil, pots, and fertilizers pertain more to gardening rather than arranging flowers. Vases, ribbons, and candles are decorative items but do not encompass the necessary tools and materials for effectively assembling floral designs, which is the focus of the question.
