corolla

Flower's petal whorl

A corolla is the ring of petals surrounding the reproductive parts of a flower.

The petals may be separate or fused into a tube, bell, or funnel shape.

In botanical description, corolla distinguishes the colorful inner whorl from the outer sepals: The corolla of the morning glory opens at dawn.
