Zucchini leaves are the large, broad leaves of the zucchini plant, which is a type of summer squash. These leaves are typically dark green and can grow quite large, often reaching up to a foot in width. They play a crucial role in photosynthesis, helping the plant produce energy to grow and develop its fruit. In addition to their role in the plant's growth, zucchini leaves are also edible. They can be cooked or used in salads, offering a mild flavor similar to other leafy greens. Rich in vitamins and minerals, they can be a nutritious addition to various dishes.
