Grow crisp, dependable greens with Parris Island Cos Lettuce—an excellent choice for fresh salads, wraps, and everyday meals.

This hardy romaine variety is known for its ability to perform well across a wide range of climates. Originally developed for challenging growing conditions, it produces upright heads with firm leaves and a mild, refreshing flavor.

These seeds are 100% heirloom, non-GMO, and open-pollinated, allowing you to grow, harvest, and replant your crop season after season as part of a self-sufficient garden.

Planting Instructions

Lettuce is a cool-season crop that grows best with consistent moisture and mild temperatures:

  • Planting Time: Sow seeds in early spring or fall for best results
  • Planting Depth: Sow seeds about 1/8 inch deep
  • Spacing: Plant seeds 8–12 inches apart
  • Row Spacing: Space rows 12–18 inches apart
  • Sunlight: Full sun preferred, though partial shade helps in warmer climates
  • Moisture: Keep soil consistently moist to support steady growth
  • Soil Conditions: Prefers loose, well-drained soil
  • Care: Water regularly and avoid disturbing shallow roots during weeding

Harvesting Instructions

Timing is key to maintaining quality and flavor:

  • Time to Harvest: Approximately 85 days from planting
  • Leaf Harvest: Outer leaves can be harvested early for continuous use
  • Full Head: Harvest entire head once it reaches full size
  • Best Quality: Pick early to avoid bitterness and tough texture
  • Harvest Method: Cut at the base or remove leaves as needed

Saving Seeds

Saving seeds from lettuce is straightforward but requires allowing plants to bolt.

Select a few healthy plants and allow them to grow beyond the harvest stage until they produce tall flowering stalks. Once seed heads form and dry, collect seeds and allow them to dry completely before storing.

Because lettuce can cross-pollinate, isolate varieties if you plan to save seeds for consistent results in future planting.
