Iceberg Lettuce is round in shape, with packed layers of  crisp green leaves. The heads are firm and tightly packed with a  central core or heart. The leaves are crunchy and have a mild flavour.  The outer leaves are a darker green; the central leaves are pale green.  The leaves are cupped, hold their shape and can be used to hold fillings. Availability All year.
