Lactuca sativa Black Seeded Simpson Lettuce Lactuca sativa Black Seeded Simpson Lettuce is a legendary heirloom loose-leaf variety, cherished for its rapid growth, delicate texture, and exceptional heat tolerance. Growing to about 9 to 12 inches tall with a spread of 10 to 12 inches, this variety is perfect for kitchen gardens, raised beds, and container plantings where reliable, early harvests are desired. Unlike heading lettuces, Black Seeded Simpson forms a loose, upright rosette of crinkled, light-green leaves that can be harvested as baby greens in as little as 3 weeks or allowed to mature for a full-sized harvest in just 45 days. Culinary and Practical Uses The crinkled, chartreuse leaves possess a crisp, juicy texture and a sweet, mild flavor that never turns bitter, making them the ultimate base for fresh spring salads. Excellent for "cut-and-come-again" harvesting; outer leaves can be snipped for sandwiches and garnishes while the center continues to grow. Rich in Vitamin A and K, this variety adds both nutritional value and a vibrant pop of bright green color to tacos, burgers, and wraps. Characteristics Foliage: Large, frilly, light green to yellow-green leaves with a crumpled surface; the texture is famously tender and delicate compared to stiffer romaine types. Growth Habit: Open, upright, loose-leaf rosette that does not form a tight heart; renowned for being one of the most heat-tolerant and bolt-resistant leaf lettuces. Flowers: Produces tall central stalks with small yellow dandelion-like flowers if allowed to bolt in extreme heat, signaling the end of the vegetative cycle. Seeds: Harvested after the flower fluff dries; true to its name, this variety produces distinctively black seeds, unlike the white seeds of many other Simpson strains. Growing Requirements Sun: Thrives in full sun during cool weather but benefits significantly from partial shade during warmer months to prolong the harvest. Soil: Prefers loose, cool, fertile soil rich in organic matter; well-draining soil is essential to prevent rot. Water: Requires consistent, even watering; lettuce is shallow-rooted and needs moisture to maintain its sweet flavor and crisp texture. Spacing: Plant seeds in wide rows or thin plants to 6 to 12 inches apart to encourage full-sized bunches; crowd closer for baby leaf production. Maintenance: Practice succession planting every 2 weeks for a continuous supply; mulch to keep soil cool and weed-free.
