A bud protector is a type of plant organ that helps protect the flower buds from damage. The sepals are the outermost layer of the bud and form a protective covering around the petals. They are typically green in color and can be either fused or separate. Sepals are important for protecting the flower buds from environmental stressors such as extreme temperatures, wind, and pests. They also help to support the flower buds as they develop.
