What is the collection of petals on a flower called?

The collection of petals on a flower is referred to as the corolla. This term is derived from Latin and specifically describes the colorful, often fragrant parts of a flower that are typically found surrounding the reproductive structures. The main function of the corolla is to attract pollinators, such as bees and butterflies, with its visual appeal and scent, which enhances the plant’s chances of successful reproduction.

In contrast, the other terms do not refer to the petals. The calyptra is a botanical term typically associated with a covering, like a cap over certain structures in plants, rather than petals. Sepals are the leaf-like structures that protect the flower bud before it opens and are usually found beneath the petals. The pistil, also not related to petals, is the female reproductive part of the flower, consisting of the ovary, style, and stigma. Understanding these definitions demonstrates the specific role that each part of the flower plays in its overall function and reproductive success.
