Dark Green Romaine Lettuce (or Cos Lettuce) is a unique heirloom lettuce producing cylindrical, upright heads. The long, cupped leaves are medium to dark green, thick and crisp and have a sweet, mild flavor. This variety is highly prized and considered a gourmet delight. For the best flavor and development, plant the crops to mature during cool weather.
Dark Green Romaine Lettuce does well with beets, bush beans, pole beans, cabbage, carrots, cucumbers, onion, radish and strawberries in your garden or containers. You can also plant your lettuce at the base of young sunflowers for a little shade.
