What type of flower is typically known for adding height to a floral arrangement?

Line flowers are typically known for adding height and structure to a floral arrangement. These flowers possess tall, sturdy stems and are used to create vertical lines in designs. By drawing the eye upward, line flowers help establish the overall shape and framework of the arrangement, contributing to its visual balance and composition.

In contrast, filler flowers serve to fill in gaps and add texture but do not contribute significantly to the height. Mass flowers are characterized by their larger blooms and are primarily used to create volume and presence rather than verticality. Accent flowers, while they may add interest and focal points to arrangements, do not primarily function to provide height like line flowers do. Therefore, line flowers play a crucial role in shaping and elevating floral compositions.
