Iceberg lettuce
Iceberg lettuce
Iceberg lettuce (pronunciation: /ˈaɪsbɜːrg ˈlɛtɪs/), also known as crisphead lettuce, is a variety of lettuce known for its crisp texture and mild flavor.
Etymology
The term "iceberg" comes from the way the lettuce was traditionally packed on ice in train cars for transportation across the United States. The heads of lettuce were said to look like icebergs, hence the name.
Description
Iceberg lettuce is characterized by its large, round, tightly packed head of pale green leaves. The outer leaves are often discarded, revealing the crisp, watery inner leaves. It is less nutrient-dense than other types of lettuce, but is popular for its crunch and is commonly used in salads, sandwiches, and wraps.
Cultivation
Iceberg lettuce is a cool-weather crop that prefers temperatures between 45 and 65 degrees Fahrenheit. It is typically direct-seeded into the garden in early spring or started indoors and transplanted outside after the last frost.
Nutritional Value
While iceberg lettuce is lower in nutrients than other types of lettuce, it is still a good source of fiber, potassium, and small amounts of vitamins A and C.
