What type of flowers are characterized by tall spikes of blossoms and serve as the framework for floral designs?

Line flowers are characterized by their tall spikes of blossoms, which create vertical lines and add height and structure to floral arrangements. These flowers provide an essential framework, guiding the eye upward and helping to define the shape of the design.

Often, line flowers are used as a foundation to build upon with other flowers and elements, creating balance and movement within an arrangement. Their elongated shapes contribute to the overall aesthetic, allowing for dynamic and visually interesting displays.

Mass flowers, on the other hand, typically have a rounded or dense shape and are used to create bulk and fill visual space. Filler flowers serve to fill in gaps and contribute texture or color without dominating the arrangement. Form flowers are unique in their shapes and are used for striking focal points rather than structural support. Hence, the distinction and purpose of line flowers in providing framework make them the correct choice in this context.
