(29 days-baby, 56 days-full size) You know this Romaine can stand up to punishing heat – it was bred in the Israeli desert! A hands-down taste test favorite, it’s easy to grow and always a winner at the table. The 14 to 16-inch heads weigh in at a surprising 2 to 3 pounds and are packed with scrumptious leaves. The bright green color is attractive, but it’s the sweet, crisp flavor of Jericho that makes it a winner every time. Jericho stands up to tip burn as well as heat, so won’t bolt when summer arrives early. It also tolerates both powdery and downy mildew, making it an excellent choice for gardeners in humid and rainy climates.
