Red Iceberg lettuce forms a rosette of tasty, nutritious, and richly red outer leaves as it grows. Eventually a tightly-packed, pale green iceberg head forms at its centre, gilded with red markings on the outside. The interior is sweet and mild, with a very pleasant, crisp texture. The head holds well against the heat of summer with a delayed seed set. This was a standout in our seed trials and drew a lot of attention.
