Lettuce Summer Crisp Fusion combines superior genetics from romaine and green-leaf varieties, delivering wavy, dark green leaves with a distinctive upright growth habit that sets it apart in the garden. This slow-bolting cultivar produces exceptionally heavy heads with abundant leaf counts that remain fully open at maturity—a key advantage over standard Summer Crisp types. The variety excels in warm-season growing, with proven heat tolerance and strong resistance to corky root disease, plus intermediate resistance to lettuce mosaic virus, making it ideal for southern gardens and extended harvest windows. Mature plants are ready for harvest in approximately 50 days from transplant. These Non-GMO, open-pollinated seeds offer an 80% or higher germination rate, ensuring reliable establishment and consistent yields. Sustainably packaged to align with environmentally conscious growing practices, Summer Crisp Fusion is a dependable choice for home gardeners seeking quality, disease-resistant lettuce that performs reliably through summer heat.
