sepal
Green petal underlayer
A sepal is one of the leaf-like structures that form the outer part of a flower, typically green and protective.
Sepals enclose and shield the developing bud before it opens, then spread apart as petals emerge.
Collectively, the sepals form the calyx.
In some flowers, sepals are colorful and petal-like; in others, they fall away after blooming.
