Black Oil Sunflower is a tall, seed-producing heirloom that brings a bold presence to the garden and an opportunity to grow your own bird-feeding seed heads. This packet contains 100 non-GMO, heirloom seeds for planting. Plants may reach approximately 8 feet, with large heads described at around 15 to 18 inches under favorable conditions; actual size varies with soil, spacing and care.

Watch a young planting develop into tall stems topped with broad sunflower heads, then follow the transition from flowering to seed maturity. Black seeds are a familiar choice for bird feeding, and selected heads can be left for visiting birds or harvested for drying. Birds may take seed before you do, so plan whether you want a wildlife display or a collected harvest.

Black oil sunflower seed is also associated with oil production, but home oil pressing requires suitable equipment, properly prepared harvested seed and appropriate food-safety practices. This packet is planting seed, not ready-to-eat food, feed or a guaranteed oil yield. For most home gardeners, the simplest use is enjoying the flowers and mature heads in a managed bird-friendly planting.

Germination Rate: 92%. Test Date: 4/26. TLM.

Why Choose Black Oil Sunflower?

• Tall garden presence: Large plants bring height and structure to a suitable sunny space.
• Seed-producing heads: Grow mature heads for bird interest or deliberate seed collection.
• Black seed type: A familiar sunflower choice associated with bird feeding and oil production.
• Garden observation: Enjoy the full progression from seedling to flower and developing seed head.
• Heirloom seed: An open-pollinated choice. Seed saving requires appropriate isolation if maintaining variety characteristics matters.

Planting Tips for Success

• Timing: Sow after frost danger has passed and soil has warmed, following packet and local guidance.
• Sunlight: Choose full sun for strong growth and flowering.
• Soil: Use well-drained soil and incorporate compost as appropriate.
• Sowing: Follow packet instructions for depth and spacing. A seed count alone does not establish an acreage or square-foot coverage rate.
• Space: Allow room for mature plants and harvesting access. Avoid crowding if large heads are your goal.
• Watering: Maintain moisture during establishment and adjust later watering to soil, rainfall and heat.
• Fertilizing: Follow soil-test or fertilizer-label guidance rather than heavy, unnecessary feeding.
• Support: Tall stems and heavy heads may need staking in windy or exposed locations.
• Seed maturity: Allow heads to develop fully before collection. Head position alone is not a reliable sign that seed is ready or protected from birds.
• Drying: Dry collected heads and seed thoroughly in a suitable airy location before storage. Discard moldy material.
