A groom's boutonniere is a small floral decoration worn on the lapel of a groom's suit or tuxedo during a wedding. Typically made from a single flower or a small cluster of flowers, it serves as a symbol of the groom's role in the ceremony. The boutonniere is often chosen to complement the bride's bouquet and the overall wedding theme. Traditionally, the groom's boutonniere is pinned on the left side of the jacket, close to the heart. It is usually made from fresh flowers, but can also be crafted from fabric or other materials for a more lasting keepsake. The boutonniere is an important accessory that adds a touch of elegance to the groom's attire.
