Pelleted Seed Lettuce Summer Crisp Muir is a distinguished Batavian variety engineered for exceptional warm-season performance, delivering reliable production when heat challenges conventional lettuce cultivation. This organic, non-GMO, open-pollinated, pelleted seed variety produces densely formed closed heads with characteristically light green, extra-wavy foliage that creates visually appealing plants while providing substantial leaf mass for generous harvests. The distinctive leaf texture contributes to the exceptional crispness that defines Muir's culinary appeal. Muir's heat tolerance is its defining strength, enabling consistent production throughout spring and summer months when gardeners typically face lettuce scarcity. The slow bolting tendency dramatically extends your productive harvest window, allowing weeks of continuous picking before plants transition to flowering. This extended productivity makes Muir exceptionally valuable for regions with warm climates or for gardeners seeking uninterrupted lettuce availability across multiple seasons. The variety's versatility extends beyond traditional soil cultivation. Muir performs exceptionally well in hydroponic systems, making it ideal for controlled-environment agriculture and innovative growing techniques. The dense head structure supports both early harvesting of tender young plants and full maturation for maximum yield, providing flexibility in harvest timing and management strategies. Expect mature heads in approximately 60 days under favorable conditions, with organic seed germination rates around 80%, ensuring reliable establishment. The open-pollinated genetics enable seed saving, allowing you to perpetuate superior plants across multiple seasons. Muir offers comprehensive value for gardeners seeking resilient, flavorful summer lettuce production in diverse growing environments. Pelleted seed coating ensures precise spacing and reduced thinning labor.  The variety demonstrates strong adaptability across soil types and climates, reducing variability in yield and quality. Packaging uses reusable, recyclable, and climate-conscious materials aligned with responsible stewardship.
