Discover helpful answers about growing Giant Titan Sunflowers, their impressive flower heads, and harvesting mature seeds.
Giant Titan Sunflowers can reach approximately 10–14 feet tall in favorable conditions. Their flower heads can become exceptionally large, sometimes approaching 24 inches across. Actual size depends on the seed variety, sunlight, soil fertility, watering, and growing conditions.
Sow Giant Titan Sunflower Seeds in spring after the danger of frost has passed and the soil has warmed. In warm climates, plant during a suitable growing period when temperatures support germination. Choose a sunny location and provide enough space for the plants to reach their full height.
Seeds are generally ready when the flower head matures, the back turns yellow-brown, and the seeds become plump and well-developed. Cut the mature head, allow it to dry in a protected, ventilated location, and remove the seeds when dry. Store fully dried seeds in a cool, dry place.
