Which of the following flowers is considered a form flower?

The Bird of Paradise is considered a form flower due to its unique structure and bold, sculptural appearance. Form flowers are characterized by their distinct shapes and forms that can serve as focal points in floral arrangements. They often possess a strong visual impact and can dramatically influence the overall aesthetic of a bouquet or display.

The Bird of Paradise, with its striking shape resembling a bird in flight and vibrant colors, stands out in any floral composition, making it an ideal choice for this category. Its structural qualities allow it to be used effectively in arrangements that require a standout element, thus reinforcing its classification as a form flower.

In contrast, while the other choices like the Carnation, Peony, and Aster each possess their own beauty and are popular in arrangements, they are generally considered filler or mass flowers rather than form flowers. Mass flowers are typically denser and contribute to the overall texture and color rather than serving as a distinct focal point.
