Which of the following materials is commonly used for reinforcing flower stems in corsages?

Wire is commonly used for reinforcing flower stems in corsages because it provides the necessary support and stability to delicate flowers. When flowers are arranged in a corsage, the stems can sometimes be fragile or too soft to hold their shape, especially when being worn on clothing or in a hairpiece. The use of wire allows florists to strengthen the stems, ensuring that the flowers maintain their position and do not droop over time.

Additionally, wire can be easily shaped and bent to fit the desired form of the corsage. Florists often use various gauges of wire depending on the thickness of the stems and the overall design of the corsage. This reinforces the structural integrity while maintaining an aesthetic appearance, as wires can be concealed among the foliage and other decorative elements.

Other materials, such as twine, may offer some utility in tying or bundling stems but do not provide the same level of shape retention and structural reinforcement as wire. Plastic clips and metal rods might be used in other contexts but are less common in corsage preparation due to their lack of flexibility and potential for being visible in the final arrangement.
