"Add crunch to your salads and sandwiches with this classic iceberg! Medium-large, round, very firm heads are covered by overfolding, fringed dark green leaves. Harvest young for baby greens! Does well in most US regions. Slow bolting. Resistant to cold damage and sunburn. Very well adapted to hot and adverse conditions." - Willhite Seed Company
