3057 - Iceberg. 65 days. Not to be confused with the generic term for head lettuce, this Batavian variety is an heirloom more than a century old. Golden green leaves with wavy pink margins form large soft oval heads. Unique color and upright form for salad mix. Good resistance to downy mildew and Sclerotinia. Sow every 3 weeks for a continuous supply. For direct-seeding full-size heads, plant 3 seeds every 8‚Äù, 0.5cm deep, in rows 12‚Äù-18‚Äù apart. Thin to one seedling per group. For transplanting, 3-4 weeks prior to moving outdoors sow in flats at 4 seeds/inch or in small-cell plug trays, barely covering seeds with fine vermiculite.
