Which type of flowers is characterized by a single stem with large rounded heads?

Mass flowers are defined by their large, rounded blooms that typically grow on a single stem. These characteristics make them ideal for creating focal points in floral arrangements. Their size and shape enable mass flowers to provide fullness and a robust presence, which can effectively fill spaces within the design.

This type of flower is often used in significant arrangements due to its visual weight, enabling it to stand out and draw attention. Popular examples include hydrangeas, peonies, and large gerbera daisies, which exhibit these attributes. Understanding the role of mass flowers is crucial for designers as they form the foundation upon which other elements of the arrangement can be built, helping to achieve balance and harmony in the overall design.
