Introducing Lettuce Romaine Jericho—an exceptional heat-tolerant heirloom originating from Israel, engineered by nature to excel where conventional romaines falter. This variety produces tall, heavy heads with bright light green, silky-smooth leaves that maintain sweetness, tenderness, and crispness even during intense early summer heat. Unlike standard romaines prone to bolting and tipburn stress, Jericho demonstrates remarkable resistance to both conditions, ensuring consistent quality harvests across challenging growing seasons. The flexible harvest window accommodates diverse gardening strategies: tender baby leaves emerge in approximately 29 days for early-season salads, while full-size heads develop in 57 days for extended production. With germination rates of 80% or higher, these seeds establish reliably and perform predictably. Certified organic and Non-GMO, Jericho represents sustainable heirloom genetics ideal for home gardeners and market growers seeking dependable, heat-resilient romaine production. Seeds arrive in eco-conscious, reusable, and recyclable packaging that aligns with environmentally responsible gardening practices.
