Black Seeded Simpson Organic Lettuce

Grow crisp, heat-tolerant lettuce with ruffled leaves using Black Seeded Simpson – a classic heirloom variety that produces loose-leaf lettuce with light green, frilly leaves and exceptional crunch. This reliable lettuce is slower to bolt than many varieties, making it perfect for extended spring and summer harvests, fresh salads, and sandwiches.

Growing Information

• Planting: Direct sow or transplant in early spring through summer; plant seeds 1/4 inch deep, 6-8 inches apart
• Spacing: Rows 12-18 inches apart
• Sun: Full sun to partial shade (4-6 hours daily)
• Zones: 3-9 (cool-season crop, heat-tolerant)

Harvest & Use

Begin harvesting when leaves reach 4-6 inches long – pick outer leaves for continuous production or cut entire plant at soil level. The crisp, ruffled leaves are perfect for fresh salads, sandwiches, lettuce wraps, and garnishes. The mild, sweet flavor and crunchy texture make these ideal for everyday eating. Slower to bolt than many lettuces, extending your harvest window into warmer weather. Store harvested lettuce in the refrigerator for up to a week.

Care Tips

Black Seeded Simpson lettuce thrives in cool weather but tolerates heat better than most varieties. Water consistently – about 1 inch per week – to prevent bitterness. Mulch to conserve moisture and keep roots cool. Plant in early spring or late summer, or use succession planting every 2 weeks for continuous harvest. Provide afternoon shade in hot climates for best quality. Companion plant with radishes, carrots, or herbs for optimal garden health.
