The leaves of garlic look like a slender sword. The leaves are oblong or flat, with a length of about 20 to 30 cm and a width of about 3 to 5 cm. The color is usually dark green, sometimes purplish or grayish white. The surface of the leaves is smooth, and there are roots at the bottom, which extend from the roots of the leaves.

Garlic leaves are one of the important parts of garlic plants. They are the main organs of garlic for photosynthesis, and make food by absorbing sunlight and carbon dioxide.
