75 days. For climates where spring and fall are brief, growing iceberg lettuce can be a real challenge. Before the heads are mature, the heat and humidity set in, bringing downy mildew with them. Calmar is a real boon to gardeners in these regions, because it tolerates unseasonable heat and resists downy mildew beautifully!
Of course, the best feature of any lettuce is its flavor, and Calmar has this to spare! Tightly packed, it fills quickly, locking in the flavor and crisp texture of this lettuce. Good outer leaf coverage, with nice ruffling, helps keep the sun away from these tender leaves.
Calmar sets quite large heads of crisp, slightly peppery, refreshing leaves. They have the distinctive iceberg texture, never limp, and nice icy-green coloring. Make this a staple of your lettuce garden no matter what climate you live in! Packet is 1/32-ounce, which is at least 600 seeds.
