What Makes Survival Garden Seeds Different - non-GMO heirloom seeds

Grow flavorful, high-performing brassicas with the Broccoli Seed Collection from Survival Garden Seeds. This trio of cool-season broccoli varieties—Waltham 29, Romanesco, and Green Sprouting Calabrese—offers dependable harvests, excellent cold tolerance, and abundant side shoots for extended production. Each variety grows well in garden beds, large containers, raised beds, or indoor hydroponic systems, giving home growers plenty of flexibility in how and where they plant.

Broccoli is an outstanding choice for fall and early winter harvests, and it also makes a nutrient-rich microgreen for sprouting. These varieties produce well-formed crowns, tender stalks, and flavorful florets that suit everything from fresh eating to roasting and freezing.

Varieties Included in the Broccoli Seed Collection:

  • Waltham 29 Broccoli: A classic blue-green broccoli known for reliable heads measuring 4–8 inches across. Plants produce generous side shoots after the primary head is harvested, extending your season. Cold tolerant and well suited for fall through early winter planting.

  • Green Sprouting Calabrese: A flavorful Italian heirloom producing large 5–8 inch heads followed by numerous side shoots. Known for tender florets and vigorous growth, making it an excellent staple variety.

How to Grow:
Start seeds indoors for spring planting or sow directly outdoors in late summer for fall and early winter harvests. Plant in full sun and provide rich, well-drained soil. Space plants about 12 inches apart to allow for full head development. Keep soil consistently moist and harvest heads promptly to prevent bolting. After removing the central head, continue harvesting side shoots regularly to prolong production. Broccoli grows best in cool temperatures and may struggle in high heat.

Cool Season Crop

In general, broccoli seeds should be planted in early spring, about 4-6 weeks before the last expected frost date in your area. You can also plant broccoli in the fall about 85-100 days before the first expected frost date in your area. This timing will allow the plants to mature and produce heads before the weather gets too cold.

If you choose to start seeds indoors, sow the seeds about ¼ inch deep. Keep the soil moist and warm (around 70°F) until the seeds germinate. Once the seedlings have 2-3 true leaves, they can be transplanted into the garden.

If you choose to sow the seeds directly outdoors, sow the seeds about ¼ inch deep and cover lightly with soil. Keep the soil moist until the seeds germinate and the seedlings are well-established.

Make sure the broccoli plants get plenty of sun (at least 6 hours per day) and water regularly. Also, make sure to space the plants about 18-24 inches apart to allow for proper growth and air circulation.
