Parris Island Cos (Lactuca sativa) is THE classic, large, sweet and crisp Romaine lettuce. Very popular with market growers – and for good reason. This is a vigorous, upright-growing, dark-green romaine that has been remarkably heat-tolerant here at Mano Farm…staying sweet and succulent through 100-degree days! Performs even better during the cold months in mild-winter climates. Excellent staple lettuce for heads or chop. Annual
