The term 'Bouquet Decoration' can be summarized by the four-letter word 'FERN'. Ferns are a type of plant that have been used in bouquet decorations for centuries. They are known for their delicate fronds and lush green foliage, which add texture and color to any arrangement. Ferns are also popular because they are relatively easy to care for and can last for weeks or even months when properly cared for.
