{"product_id":"romaine-jericho-lettuce-seeds-organic","title":"Romaine, Jericho Lettuce Seeds (Organic)","description":"\u003cp\u003eJericho is an upright green romaine selected for warm growing conditions, with crisp leaves and a sweet, mild flavor for salads, sandwiches, and wraps. Gardeners can harvest it as young leaf lettuce or allow plants to develop more mature romaine heads. Its 28–58-day maturity range reflects those different harvest stages. This organic seed can be sown for a cool-season lettuce crop while giving growers flexibility to pick leaves at the size they prefer. Full sun to part shade and generous spacing support the tall, open romaine form.\u003c\/p\u003e\n\u003ch3\u003eVariety Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBotanical name:\u003c\/strong\u003e \u003cem\u003eLactuca sativa\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant type:\u003c\/strong\u003e Hardy annual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLettuce type:\u003c\/strong\u003e Upright green romaine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlavor and texture:\u003c\/strong\u003e Sweet, mild, and crisp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarvest options:\u003c\/strong\u003e Young leaves or more developed heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePacket:\u003c\/strong\u003e Approximately 500 seeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSowing \u0026amp; Growing\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil temperature:\u003c\/strong\u003e 45–65°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlanting depth:\u003c\/strong\u003e 1\/4–1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGermination:\u003c\/strong\u003e 7–14 days\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDays to maturity:\u003c\/strong\u003e 28–58 days, depending on harvest stage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSun:\u003c\/strong\u003e Full sun to part shade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacing after thinning:\u003c\/strong\u003e 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature height:\u003c\/strong\u003e Approximately 5–7 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUse a fine, prepared seedbed and keep the shallow sowing zone evenly moist until seedlings emerge. If you plan to grow full romaine heads, preserve the listed spacing after thinning so each plant has room to develop. For baby-leaf use, begin harvest earlier and select clean outer leaves or cut plants at the stage you want. In warm weather, check soil moisture and plant condition regularly rather than relying on a fixed watering schedule. Record sowing and harvest dates to learn which part of the maturity range fits your season. Harvest during the cooler part of the day when possible and move leaves out of direct sun.\u003c\/p\u003e\n\u003cp\u003eCompare this variety with other options in our \u003ca href=\"\/collections\/lettuce-seeds\"\u003eLettuce Seeds\u003c\/a\u003e collection.\u003c\/p\u003e","brand":"Peaceful Valley","offers":[{"title":"Pack","offer_id":41622924558449,"sku":"SNV8473","price":3.49,"currency_code":"USD","in_stock":false},{"title":"1oz","offer_id":41622924525681,"sku":"SNV8473B","price":19.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0061\/1391\/9089\/files\/organic-lettuce-romaine-jericho.jpg?v=1747079786","url":"https:\/\/www.groworganic.mom\/products\/romaine-jericho-lettuce-seeds-organic","provider":"Grow Organic","version":"1.0","type":"link"}
