The outer leaves of this lettuce are crisp and green, while the interior leaves, which are not exposed to light, are yellow or white. Common lettuce cultivars are derived from the species Lactuca sativa, which is native to Eurasia and a member of the daisy family, Compositae. There are four primary types of lettuce based on their growth habits and shape: crisp-head, butter-head, leaf, and cos or romaine. Crisphead is often erroneously referred to as icebergi, which is actually a specific variety of this type of lettuce. 1994 marked the 100th birthday of iceberg lettuce, which was discovered quite by accident. On their Fordhook Farm in Doylestown, Pennsylvania, the Burpee family had cultivated Batavia, or “cabbage-head” lettuce with potential Celtic origins. Someone observed a cranium with an unusual appearance that was large and well-blanched in the centre. It was unusually crisp and regarded sweet due to its significantly milder flavour than the rest. Because they liked what they saw and tasted, they collaborated with other American growers to enhance it. As a consequence, there are numerous iceberg varieties today.
In Australia, iceberg lettuce is the most widely used type and is used in everything from sandwiches to coleslaw. Its leaves have a firm, crisp texture and are a light green color. Iceberg lettuce is always available and has a flavor that is refreshing.
