Which type of flower is characterized by having many small heads on multiple stems?

The type of flower characterized by having many small heads on multiple stems is known as branched fillers. Branched fillers are often used in floral arrangements to add texture and volume. They are typically made up of a single stem that branches out, each branch featuring several small blooms. This structure allows for a fuller appearance in arrangements, making them popular for creating depth and interest.

Feathery fillers, on the other hand, are usually more delicate and airy, lacking the multiple heads that define branched fillers. Mass flowers consist of large blooms singularly placed to create focal points rather than branching out. Line flowers are noted for their height and linear form, providing structure but not the cluster effect seen in branched fillers. Thus, branched fillers stand out because of their distinctive feature of multiple heads on several stems, enhancing the overall design of floral compositions.
