Green Leaf Lettuce

Lactuca sativa 'Grand Rapids'

vegetable

Grand Rapids is the classic green leaf lettuce, a loose-leaf non-heading type that forms a large, open rosette of bright, light-green leaves with deeply frilled and crinkled edges. Bred originally for greenhouse forcing, it is fast, vigorous, and one of the most widely grown green leaf lettuces, with a mild, sweet flavor and a crisp, tender texture. It is slower to bolt than many leaf lettuces and well suited to cut-and-come-again harvesting, making it a dependable choice for spring and fall salads.

🌾 Harvest & storage

Begin picking the outer leaves once the plant is 4 to 6 inches tall, taking a few from each plant cut-and-come-again, or cut the whole rosette an inch above the crown to regrow for another cutting. Harvest in the cool of the morning when the leaves are crispest, and pick before the plant sends up a flower stalk, after which the leaves turn bitter and the sap milky. The tender leaves keep only about a week refrigerated in a sealed bag.

🥗 Nutrition & benefits

Loose-leaf lettuce is very low in calories and a good source of vitamins A and K, with folate and small amounts of vitamin C and iron. The greener outer leaves carry more nutrients than the pale inner ones, and leaf lettuce is far more nutritious than crisphead types like iceberg.
