## Definition

the part of a flower that is made of all the petals together. It is usually the colorful part that attracts bees and butterflies.

For teachers: the inner envelope of a flower, consisting of the petals. It is typically distinct from the outer calyx and serves to attract pollinators through color or scent.

## Examples

- The bright red corolla attracts many hummingbirds.
- The botanist examined the shape of the corolla to identify the specific species of orchid found in the valley.
- In many plant families, the individual petals of the corolla are fused into a tube-like structure, a morphological adaptation that restricts access to nectar to specific insect species.

## Usage notes

- Often used in technical botanical descriptions to refer to the petals as a collective unit.
