Quick Summary

Treasure flower
Treasure flower The radiate head of the treasure flower (Gazania rigens), a daisylike inflorescence composed of disk flowers in the center surrounded by marginal ray flowers.

The term "radiate head" refers to a type of flower head found in plants of the Asteraceae family, also known as the composite family. This family includes familiar plants like daisies and sunflowers.1

A radiate head is characterized by having disk flowers in the center, surrounded by one or more rows of ray flowers. These ray flowers are the petal-like structures that extend from the center, giving the head its distinctive appearance. In some species, like chicory, the entire head may consist only of ray flowers. The Asteraceae family is one of the largest plant families, with over 25,000 species found worldwide.12
