What is the purpose of using a plant stem as a base for a boutonniere?

Using a plant stem as a base for a boutonniere primarily serves the purpose of providing support. The stem is essential because it allows the floral components to be held together securely, ensuring the boutonniere maintains its shape and is properly presented when worn on a lapel. This structural integrity is crucial, especially for arrangements that may have multiple flowers or delicate elements, as it keeps everything aligned and reduces the risk of damage or disarray.

While color, fragrance, and weight can have roles in floral design, the fundamental need for the boutonniere to stay intact and properly positioned relies on the support the stem offers. Without this support, the boutonniere could fall apart or not be worn effectively, emphasizing the importance of the stem in creating a polished and functional floral accessory.
