Iceberg Lettuce Seeds (Lactuca sativa var. capitata) – 2500+ Non-GMO Heirloom Seeds for Planting, Classic Crisphead with Cool, Crunchy Leaves, by Isla’s Garden Seeds, Gift Idea for Gardeners
Iceberg Lettuce (Lactuca sativa var. capitata) forms tight, round “crisphead” heads with pale-green, crunchy leaves and mild, refreshing flavor. A salad staple, it brings classic texture to wedges, sandwiches, burgers, and chopped salads.
A cool-season favorite, Iceberg performs best in spring and fall. Heads are uniform and dense when grown in fertile, well-draining soil with steady moisture. Plants reach 10–12 inches across and hold well when temperatures remain mild.
Harvest whole heads when firm and well-filled, or pick outer leaves earlier for kitchen use while heads size. For the crispiest texture, chill harvested heads promptly before serving.
Dependable, crunchy, and versatile, Iceberg Lettuce is an essential for gardeners who love classic salads and fresh, crisp greens straight from the garden.

Sow as soon as soil can be worked in spring, or late summer for fall harvests. Choose a site with full sun to light afternoon shade and rich, well-draining soil. Successive sow every 2–3 weeks for a steady supply.
Direct sow 1/8 inch deep in rows 12–18 inches apart; keep the seedbed evenly moist for uniform germination (7–14 days). Thin seedlings to 12–16 inches to allow heads to form tightly. Mulch lightly to moderate soil temperature and retain moisture.
Maintain steady moisture to prevent bitterness and tip burn. Harvest when heads feel firm when gently pressed. In warming weather, provide shade cloth or harvest earlier to avoid bolting.
