                &lt;p&gt;Leaf vegetables, also called potherbs, greens, vegetable greens, leafy greens, or salad greens, are plant leaves eaten as a vegetable, sometimes accompanied by tender petioles and shoots. Nearly one thousand species of plants with edible leaves are known.&lt;/p&gt;

                &lt;p&gt;Leaf vegetables are typically low in calories and fat, and high in protein per calorie, dietary fiber, vitamin C, pro-vitamin A carotenoids, folate, manganese and vitamin K.&lt;/p&gt;
