Which flowers are usually characterized by single stems and large rounded heads?

Mass flowers are typically characterized by having single stems and large, rounded heads. These flowers are designed to create a bold, full effect in floral arrangements, making them ideal for adding substantial visual weight and focal points. Common examples of mass flowers include peonies, dahlias, and hydrangeas. Their larger blooms and sturdy stems allow them to stand out prominently in arrangements.

In contrast, form flowers have unique shapes that contribute artistic elements to designs, but they do not have the same single-stem, rounded head characteristics. Skeleton flowers typically refer to more delicate, thin-stemmed flowers that serve as structural outlines in arrangements, making them less suitable for this description. Accent flowers, while they enhance bouquets through color and texture, usually consist of smaller blooms and do not dominate with large heads like mass flowers do. Understanding these distinctions helps in selecting the right flowers for specific design purposes in floral arrangements.
