Ease of Cultivation and uses: The ‘Maximilian’ sunflower is a perennial variety known for its stunning golden-yellow blooms and ability to thrive in a variety of conditions. This sunflower is relatively easy to grow, making it a great choice for both beginners and experienced gardeners. It flourishes in full sun and can adapt to poor soil, making it a versatile addition to any garden. The vibrant flowers attract pollinators and can also be used for cutting, adding bright, cheerful color to floral arrangements.

Direct Sowing: For direct sowing, plant ‘Maximilian’ sunflower seeds outdoors in the spring after the last frost date when soil temperatures are around 60°F. Sow the seeds 1 inch deep and space them 18–24 inches apart in rows that are 2–3 feet apart to allow ample space for growth. Water the seeds thoroughly after planting and maintain consistent moisture until germination, which typically occurs within 10–14 days. These sunflowers can tolerate some drought once established, making them relatively low-maintenance.

Early Sowing for Seedlings: To get a head start, sow sunflower seeds indoors 4–6 weeks before the last expected frost. Use seedling trays filled with a quality potting mix, placing one seed per cell and covering it lightly with soil. Keep the temperature around 70°F to promote germination. Once the seedlings develop their first true leaves and the danger of frost has passed, transplant them into the garden, spacing them 18–24 inches apart. Water them well after planting to encourage strong root development.

Harvesting: To know when ‘Maximilian’ sunflowers are ready to harvest, watch for the flower heads to droop and the backs to turn brown. This indicates that the seeds are mature. Cut the flower heads in the morning when they are dry, leaving several inches of stem for easy handling. If you wish to collect seeds, allow the heads to dry completely, or cover them with a paper bag to protect them from birds and pests until you are ready to harvest.
