Helianthus annuus. Easy to grow in full sunlight, they should be sown in well-draining, loamy soil after the danger of frost has passed. Plant the seeds 1⁄2" deep and keep the seedbed uniformly moist until the seedlings emerge, about 10 days after sowing. Weed carefully and keep well-watered until established. You may also start Sunflowers indoors 3 weeks before the last frost date. Plant seeds 1⁄2" deep in pots of good seed-starting mix at 65° to 85°F. Provide even moisture, strong light and good ventilation. When the seedlings are large enough to handle, thin or transplant them 12" to 24" apart in the garden. A good cut flower, this cheerful garden favorite may be planted successively every 3 weeks in the spring and early summer for more continuous blooms.
