Black Seeded Simpson is a classic heirloom loose-leaf lettuce variety featuring large, upright plants with bright lime-green, lightly crinkled and frilled leaves that form a loose rosette, often reaching 8-10 inches tall and wide. The leaves are crisp, tender, juicy, and mildly sweet with a fresh, delicate flavor that's excellent for fresh eating—inner leaves tend to blanch to a lighter color for added contrast. It's incredibly versatile: harvest young as baby greens for salads, use mature leaves in sandwiches, wraps, smoothies, or as a bed for grilled proteins, and it's a staple for mixed greens mixes or simple side salads. This variety is an outstanding choice for Utah because it's one of the most reliable and productive leaf lettuces recommended by local extensions like USU, it's cold-tolerant for early spring and fall planting, slow to bolt compared to many others, and handles our variable cool-season conditions well with good drainage and consistent moisture. It's great for containers.
