Organic Romaine Little Caeser Lettuce Seeds produce leaves smaller than a regular romaine mix, but offer excellent green outer leaves with blanched golden core leaves. Their tall, sweet, crisp heads are ideal for compact gardens and are simple to grow. The leaves of little Caesar lettuce are ideal for sandwiches and should be harvested just before eating. One mature head, which stands between 10 and 15 inches tall, is ideally portioned to serve two people. To get the most out of your salads, grow your own organic romaine little Caesar lettuce!
