Romaine - fit for a Caesar and a lot more! Romaine is truly one of the world's great Lettuces - nutritious, delicious and versatile. Romaine has medium-to-dark green, long, crisp leaves with firm white ribs almost to the tip of the leaf. As you reach the center, the Romaine Heart leaves become smaller, more yellow and sweeter. Romaine's wonderful flavor and beautiful texture have made this lettuce variety a traditional Romaine Lettuce. It's a chef's favorite, whether used for its dark green outer leaves or its tender and delectable hearts. Romaine owes much of its fame to the starring role it plays in what is probably the world's most famous salad, the Caesar (named not for a Roman ruler but a creative Mexican restaurateur). Romaine's superb combination of nutrition, taste and texture will ensure the popularity of this leaf lettuce for as long as humans love salad. Low in calories and rich in nutrients, both Green and Red Romaine are packed with nutrition. It's an excellent source of vitamin A (notably through its concentration of the pro-vitamin A carotenoid, beta-carotene), vitamin K, folate, vitamin C, manganese, and chromium. With these nutrients and its high fiber, Romaine can contribute to a heart-healthy diet.
