Crisphead Iceberg Lettuce (Lactuca sativa), is also known as Crisphead lettuce. Iceberg Lettuce is the one of the most popular types of crisphead lettuce and has been a favorite for many years. Its popularity is due to its crisp, juicy texture. While not known for its impactful flavor, iceberg lettuce has a subtle, sweet taste. It is used in salads, on sandwiches, and as a garnish. Iceberg lettuce is an annual grown in zones 4-9. They prefer cooler weather but need sunlight to grow properly. If they heat up too fast, or too early, iceberg lettuce could prematurely bolt, or go to seed. They are best when harvested just before this point when the inner leaves are firm. Heat can also cause splitting or rotting, so start lettuce in the early spring so it can be harvested before the high heat of summer. Iceberg lettuce has been a staple vegetable for many years, and is a great addition to any garden.
This variety produces crisp loose heads of bright green, frilly leaves that are sweet and delicious. This gourmet lettuce is slow to bolt and is rich in vitamins. This is a semi-heading loose-leaf lettuce, reaching 12 inches tall, and ready in only 45 days.
W.Atlee Burpee Co. first developed Green Ice lettuce and offered it to gardeners in their catalog; Green Ice comes from a cross between Grand Rapids and Fordhook lettuce varieties.
