Which flower is NOT listed as a mass flower?

A mass flower is typically characterized by its large, full blooms and ability to create a significant visual impact, often used to fill space in arrangements. The correct choice, Aster, is not considered a mass flower. While asters are beautiful and can contribute to floral arrangements, they usually feature smaller, more delicate blooms and are often utilized as filler flowers rather than to create mass or bulk within a design.

In contrast, peonies, roses, and carnations are widely recognized as mass flowers due to their larger flowers and dense petal formations, which can easily fill out arrangements and serve as focal points. Peonies boast a lush, voluminous appearance that draws attention, roses are favored for their classic beauty and are available in various sizes with many petals, and carnations, with their full heads and myriad colors, serve as staple mass flowers in the floral industry. Understanding the distinctions between these types of flowers aids florists in selecting appropriate blooms for various arrangements and design aesthetics.
