Before refrigerated transport, this was a luxury. The variety quickly became America’s most beloved salad green, prized for its tight, crunchy heads and mild, refreshing flavor. This heirloom open-pollinated strain traces back to those classic American varieties — non-GMO, grown the old-fashioned way, and every bit as satisfying straight from the garden as it is on a plate.\u003c\/p\u003e\u003ch2\u003ePlant Profile\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDays to Maturity:\u003c\/strong\u003e 70–85 days\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size:\u003c\/strong\u003e 6–8 inches in diameter; 1–2 lbs per head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Appearance:\u003c\/strong\u003e Pale green outer leaves wrapping a tight, dense, creamy white-green interior\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Height:\u003c\/strong\u003e 8–12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Type:\u003c\/strong\u003e Annual heading lettuce\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFlavor Profile\u003c\/h2\u003e\u003cp\u003eMild, clean, and refreshingly crisp — iceberg lettuce delivers that satisfying crunch that no other lettuce can replicate. The flavor is delicate and slightly sweet with none of the bitterness found in some romaine or leaf varieties. Excellent raw in salads, wedge salads with blue cheese dressing, tacos, burgers, and wraps. Holds up well after washing and stores beautifully in the refrigerator for up to two weeks.\u003c\/p\u003e\u003ch2\u003eGrowth Type \u0026amp; Harvest Yields\u003c\/h2\u003e\u003cp\u003eIceberg lettuce forms a single dense, compact head per plant.
