A historic French crisphead (iceburg) lettuce, from the late 1800’s , also known as Reine Des Glaces . Outer leaves are ruffled with jagged edges and tucked inside is a crispy textured head. It stood out in our trials, having formed beautiful heads with excellent heat tolerance. We see why this one has been grown in gardens for over a century.
