Start it early in the season and by early summer you’ll have tons of sweet broccoli. Cut the central head, then lay the plant over on its side for an explosion of side shoots that will just keep coming until the heat of summer. In relatively cool areas, this one crop may continue to produce for 6 months or longer. No fall crop needed — just keep it trimmed and enjoy the rewards. Very frost-tolerant. 60–90 days.\u003c\/p\u003e\u003cp\u003eThe 1947 Pike Seed Company said it best: \u003cem\u003e“Italian early Green Sprouting, producing large heads of tender green sprouts.”\u003c\/em\u003e\u003c\/p\u003e\u003ch3\u003eWhy Grow Green Calabrese?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVery frost-tolerant\u003c\/strong\u003e — one of the hardiest broccoli varieties available\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUp to 6 months of production\u003c\/strong\u003e — in cool areas, one planting keeps producing all season\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge 3–6 inch dark green heads\u003c\/strong\u003e — richly flavored, far superior to store-bought\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide shoot explosion trick\u003c\/strong\u003e — lay the plant on its side after the main harvest for a massive flush of shoots\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItalian heirloom pedigree\u003c\/strong\u003e — documented since at least 1947; a true garden classic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent for microgreens\u003c\/strong\u003e — harvest at the micro-leaf stage for a tender, nutrient-dense superfood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen-pollinated heirloom\u003c\/strong\u003e — save seed year after year\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eGrowing Notes\u003c\/h3\u003e\u003cp\u003eStart 4–6 weeks before the last frost indoors, or direct sow in late summer for a fall crop. Transplant outdoors when seedlings are 4–6 inches tall, spacing 18–24 inches apart in full sun. Water consistently and deeply. Harvest the main head when tight and firm, before flowers open. After harvest, lay the plant on its side — this triggers an explosion of side shoots for a continuous extended harvest. In cool areas, a single planting can produce for 6 months or longer without replanting.\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDays to Maturity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e60–90 days from transplant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eProduction Window\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eUp to 6 months in cool areas\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHead Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3–6 inches diameter, dark green\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlant Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18–28 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrost Tolerance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVery frost-tolerant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBest Uses\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFresh eating, steaming, freezing, canning, microgreens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePlant Spacing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18–24 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull sun\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eItaly; documented by Pike Seed Co. 1947\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eUSDA Zones\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3–12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eLatin Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cem\u003eBrassica oleracea\u003c\/em\u003e var. \u003cem\u003eitalica\u003c\/em\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHeirloom, Open-Pollinated, Non-GMO, Annual\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003cem\u003ePacked and shipped by Box Garden Seeds LLC — heirloom seeds grown without GMOs, selected for flavor, resilience, and your garden’s success.\u003c\/em\u003e\u003c\/p\u003e","brand":"Box Garden Seeds LLC","offers":[{"title":"2g \/ ~200+ seeds","offer_id":44236518981766,"sku":"ABS-80-123-2028","price":3.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2669\/3330\/files\/il_fullxfull.7658546367_4ycl.jpg?v=1770127466","url":"https:\/\/bgseedsllc.com\/products\/green-calabrese-broccoli-heirloom-seeds","provider":"Box Garden Seeds LLC","version":"1.0","type":"link"}
