Broccoli Seed Collection – 5 Heirloom Varieties for Cool-Season Gardens

Grow more than one “kind of broccoli” with this Broccoli Seed Collection featuring five heirloom varieties selected for cool-season success and dependable home garden harvests. This diverse mix combines classic green heading broccoli, striking Romanesco spirals, purple sprouting types, and early raab for a longer, more versatile harvest window. Included varieties are Calabrese Broccoli and Waltham 29 (Brassica oleracea var. italica), Purple Sprouting Broccoli (Brassica oleracea var. italica), Romanesco Broccoflower (Brassica oleracea var. botrytis), and San Marzano Raab (Brassica rapa). Together, they offer traditional crowns for everyday meals, tender raab shoots for early harvest, and colorful side shoots that continue producing after the main heads are cut. Reliable Cool-Season Performance: • 5 heirloom broccoli and raab varieties for diverse harvests • Includes heading, sprouting, Romanesco, and rapini types • Best suited for cool weather growing (55–75°F) • Performs well in USDA Zones 3–10 • Ideal for raised beds, backyard gardens, and seasonal planting Why Customers Love Broccoli Seed Collection: • Extended harvest window from early raab to late side shoots • Classic green crowns plus unique purple and spiral varieties • Strong kitchen versatility for roasting, steaming, stir-fries, and salads • Family-friendly mix that adds color and texture to meals • Suitable for spring and fall planting in most regions How to Grow: Start seeds indoors 6–8 weeks before your last frost, or direct sow outdoors in early spring once soil temperatures reach approximately 60°F. Transplant seedlings to full sun in rich, well-drained soil. Space plants 18–24 inches apart to allow for full head development. Broccoli grows best in cool temperatures between 55–75°F. Most heading varieties mature in approximately 60–90 days. Harvest main heads while tight and firm, then allow sprouting and side-shoot types to continue producing smaller shoots for additional harvests. Harvest & Use: Cut central heads before florets begin to open. Raab (rapini) can be harvested earlier for tender stems and leaves. Purple sprouting types and Romanesco continue producing side shoots after the main cut, extending your harvest. Enjoy fresh broccoli roasted, steamed, sautéed, or added to stir-fries and salads. For long-term storage, blanch and freeze for use in future meals.
