What Makes Survival Garden Seeds Different - non-GMO heirloom seeds

Grow one of the most trusted and flavorful heirloom lettuces with Black Seeded Simpson Lettuce Seeds (Lactuca sativa). This fast-growing, loose-leaf variety produces tender, light-green leaves with a crisp texture and mild, refreshing flavor. A garden favorite since the 19th century, Black Seeded Simpson is known for its reliability, adaptability, and delicious taste.

Fast, Easy, and Productive:
Black Seeded Simpson lettuce matures quickly—ready to harvest in just 45–50 days. It thrives in a wide range of conditions, performing well in garden beds, raised containers, or hydroponic systems. This variety is heat-tolerant and slow to bolt, making it an excellent choice for both spring and summer planting.

Why Gardeners Love Black Seeded Simpson Lettuce:

  • Classic heirloom lettuce with light-green, frilly leaves
  • Mild, crisp flavor ideal for salads, wraps, and sandwiches
  • Quick-maturing (45–50 days) for early and continuous harvests
  • Heat-tolerant and resilient in variable weather conditions
  • Suitable for hydroponics, containers, or direct garden sowing
  • Non-GMO, open-pollinated seeds with dependable germination

How to Grow:
Sow seeds ¼ inch deep in cool, moist, well-drained soil. For early starts, plant indoors 4–6 weeks before the last frost or direct sow outdoors as soon as soil can be worked. Space plants 6–12 inches apart. Maintain even moisture and partial shade in hot weather to prevent bolting. Harvest baby leaves for tender salads or allow plants to mature for full heads.

Harvest & Enjoy:
Pick outer leaves regularly to encourage regrowth and a continuous supply of fresh greens. The mild, crisp flavor of Black Seeded Simpson lettuce makes it a perfect base for garden-fresh salads, sandwiches, or wraps. Its adaptability to hydroponic systems also makes it ideal for year-round indoor growing.
