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

Grow towering, high-yield sunflowers with the Edible Sunflower Seeds Collection, featuring two classic heirloom non-GMO varieties—Mammoth and Black Russian. These dual-purpose giants deliver both spectacular golden blooms and abundant edible seeds, perfect for roasting, snacking, or feeding backyard birds.

Reaching 8–12 feet tall, these sunflowers produce massive flower heads packed with oil-rich seeds while creating a stunning focal point in the garden. Ideal for homesteads, pollinator gardens, and large landscapes, they combine ornamental beauty with practical harvest value.

Towering, Productive, and Pollinator-Friendly:

  • Includes two giant heirloom types: Mammoth (bright yellow petals) and Black Russian (gold petals with dark centers).
  • Produces hundreds of large, edible seeds per bloom for roasting or bird feed.
  • Creates bold, structural height and vibrant summer-to-fall garden color.
  • Supports bees, butterflies, and birds, enriching biodiversity year-round.

Why Gardeners Love This Sunflower Collection:

  • Dual-Purpose Value – Grows for both beauty and food, producing edible seeds and wildlife feed.
  • Giant Garden Presence – 8–12 ft stalks with massive heads make perfect privacy screens or borders.
  • Easy to Grow – Thrives in full sun and well-drained soil across USDA Zones 3–11.
  • Low Maintenance – Drought-tolerant once established and reliable in hot climates.
  • Perfect for All Garden Types – Great for homesteads, large plots, or ornamental displays.

How to Grow Edible Sunflowers:

  • When to Plant: Sow seeds outdoors after the last frost when soil warms above 60°F (16°C).
  • Soil & Sun: Choose full sun and average, well-drained soil; amend with compost for best results.
  • Spacing: Allow 18–24 inches between plants to support large heads and sturdy stems.
  • Watering: Water deeply once per week to encourage strong root growth.
  • Bloom & Harvest: Blooms appear mid-summer through fall; allow heads to dry on the stalk before collecting seeds.

Harvest & Use:
Once petals fade and seed heads dry, remove and hang them to finish curing. Enjoy home-roasted sunflower seeds, share with backyard birds, or save for next season’s planting. Their towering beauty and generous harvest make this collection a favorite for gardeners seeking both productivity and visual impact.

Sun Lovers

The best time to plant sunflower seeds is in the spring when the soil has warmed up and there is no longer a risk of frost. In most regions, this is typically around mid-April to early May.

You can plant the seeds directly in the ground, or you can start the seeds indoors in small containers and transplant them outside once they have developed into seedlings.

To plant sunflower seeds directly in the ground, loosen the soil to a depth of at least 6 inches. Sow seeds about 1 inch deep and 6-12 inches apart, and place one seed in each hole. Cover the seeds with soil and water thoroughly.

You can start seeds indoors in containers. Keep the containers in a warm, sunny location and water regularly. Once the seedlings have developed true leaves, they can be transplanted outdoors.

It's worth noting that sunflowers prefer full sun and well-drained soil, so choose a location that gets at least 6 hours of direct sunlight per day and avoid areas with poor drainage.
