The name you are looking for is "sepal." Sepals are the outermost part of a flower's protective covering, typically green in color and resembling small leaves. They are often found as a group, covering and protecting the bud before it blooms. Once the flower emerges, the sepals hold up the flower from underneath, providing support and stability. The sepals can either be together, forming a collective structure, or alone, meaning they are separate from one another.
