Corolla is the collective term for petals of a flower taken as a group within the calyx. Normally the corolla is the most conspicuous part of a flower and of a bright color other than green. The concept of corolla description is widely used in botany as a primary way to identify vascular plants. The corolla extends from the calyx outwards. Within it are housed anatomy such as the corolla tube, anthers, stamen, and stigma.
