This sunflower is relatively easy to grow, making it an excellent choice for both novice and experienced gardeners. Thriving in full sun and well-drained soil, it brings a touch of sophistication to any garden. Not only does it make a beautiful addition to floral arrangements, but it also attracts pollinators and beneficial insects, enhancing the overall health of the garden ecosystem.

Direct Sowing: For direct sowing, plant ‘Italian White’ sunflower seeds outdoors in the spring after the last frost date when soil temperatures reach approximately 70°F. Sow the seeds 1 inch deep and space them 12–18 inches apart in rows that are 2–3 feet apart to allow for proper growth. Water the seeds thoroughly after sowing and maintain consistent moisture until germination, which typically occurs within 7–10 days. As the plants grow, consider providing support if they become tall and susceptible to wind damage.

Early Sowing for Seedlings: To get a head start, sow sunflower seeds indoors 4–6 weeks before the last expected frost. Use biodegradable pots filled with seed-starting mix, placing one seed per pot and covering it lightly with soil. Keep the temperature around 70°F to encourage germination. Once the seedlings develop a couple of true leaves and the danger of frost has passed, transplant them into the garden, spacing them 12–18 inches apart. Ensure to water them well after transplanting to help them adapt to their new environment.

Harvesting: To determine when to harvest ‘Italian White’ sunflowers, look for the flower heads to begin drooping and the backs to turn yellow. This indicates that the seeds are mature. Cut the flower heads in the morning when they are dry, leaving several inches of stem for handling. If you plan to collect seeds, allow the heads to dry completely before removing the seeds, or cover them with a paper bag to protect them from birds and other pests until you are ready to harvest.
