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.
  • Romanesco Broccoli: A striking lime-green heirloom with a nutty flavor and firm texture. Its signature spiral shape makes it a favorite for both kids and adults. Performs well indoors or outdoors in cool weather.
  • 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.

Why Customers Love the Broccoli Seed Collection:

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.

Frequently Asked Questions

What are heirloom seeds?

Heirloom seeds are the types of seeds your grandparents grew. These varieties have been passed down from generation to generation. They’re old reliable open-pollinated varieties that aren’t typically grown commercially. Instead, they have a rich history that predates modern breeding techniques.

You can learn more about open-pollinated, heirloom, and non-GMO seeds in our Survival Garden Training blog.

How do I know my seeds are fresh?

Every seed packet includes a "packed for" date, and we germination test each seed lot before packaging to ensure you receive viable, high-quality seeds that are ready to grow.

Are your seeds treated?

No, we do not pre-treat our farmer seeds. All of our garden seeds for sale are untreated, open-pollinated, non-GMO, and heirloom varieties. They are kept in temperature-controlled cooler storage until they are packed and shipped to keep them pest and disease-free.

In what zones can I grow your seeds?

The seeds in our collections are specifically chosen from varieties that can be successfully grown from Zone 3 to Zone 10 USDA Hardiness Zones. However, individual varieties have specific needs to thrive in different environments. Each seed pack has optimal temperatures for germination and instructions on seed starting. Consult local frost dates to plan your garden and get the most out of your seeds.

What is the shelf life of these gardening seeds?

Most seeds remain viable for 3 to 5 years or longer when stored properly. Check your seed packet for specific varieties. For best results, keep your seeds in a cool, dry place away from direct sunlight and moisture. Store them in an airtight container in a consistent temperature environment—a refrigerator or cool basement works well. Proper storage helps maintain germination rates and extends seed life well beyond the packed date.

Where are Survival Garden Seeds sourced?

The majority of our seeds are sourced in the United States, with a few exceptions when the seed is difficult to source domestically. Whenever we do have to source outside of the US, we ensure our seeds are safe to grow, non-GMO varieties that meet our standards for germination and reliability.
