What type of flowers is used to establish the outline of the floral arrangement?

The term "skeleton flowers" is often used informally in the floral industry to describe a particular type of flower that has a structure or form that can provide a framework for an arrangement. In floral design, these flowers help establish the outline or overall shape of the arrangement, making them crucial for visual stability and balance. Their often bold structure can help guide the eye and form the basis around which other elements of the design are arranged.

Form flowers possess a unique shape that helps create the silhouette and outline of a bouquet or arrangement, making them essential in defining the style and dynamics of the design. While skeleton flowers may indicate certain structured or bold types, form flowers directly refer to those with a notable shape that intricately defines the physical outline of a floral piece.

The other types of flowers mentioned do not primarily serve this purpose; accent flowers are typically used to add interest or highlight specific areas rather than setting the overall outline, while filler flowers are utilized to fill in gaps and add texture, rather than to establish the initial structure.
