Sunfinity® Yellow Dark Center Sunflower Seeds

Plant Sunfinity® Yellow Dark Center Sunflower Seeds in spring, and in summer, the plant blooms in 4-inch flower heads with bright yellow rays surrounding a dark brown center. Borne in clusters on stiff, course stems, the blooms continue over a long season, up to 12 weeks, and last a long time in a vase. Be sure to cut sunflowers in the early morning to encourage longer-lasting blooms.

Although a towering, elegant, and architectural presence in the garden, this uniform, well-branched plant is not too tall to add to the back of a bed or border in a cottage, informal, cutting, or wildlife garden, where the flowers beckon to bees, butterflies, and beneficial insects, and the tasty seeds bring the birds flocking.

A hardy annual, sunflowers are fast-growing, tough plants, both heat tolerant and pest resistant, including deer. But consider planting with chives. The onion scent helps deter aphids.

The seeds are easy to direct sow. Just pick a sunny spot with 6 to 8 hours of direct sun, moderately fertile, humus-rich, neutral to alkaline, moist soil, and good drainage, preferably sheltered from the wind. Rake to a fine tilth, clearing stones and weeds; plant seeds ½ to 1 ½ inches deep, spaced 18 inches apart; cover thoroughly with soil; and water regularly. Applying a light application of fertilizer at time of planting and watering deeply but infrequently, once the plant is established, promotes deep rooting. And succession planting, sowing a new row every two to three weeks, will keep sunflowers coming right up to the first frost.

Plants can also be started indoors and planted outdoors after the risk of frost has passed. If you plan to start your seeds indoors, be sure to check out our Bio Dome Seed Starter Kit. With the Bio Dome, you can control the temperature, light, and soil mix to ensure your seeds become strong for transplant.
