About Downy, Sunflower Seed
Downy Sunflower (Helianthus mollis) is a distinctive North American native plant. Soft gray-green foliage distinguishes this sunflower, which forms vigorous colonies and flowers generously in lean, dry soil. It matures at approximately 60 inches tall and flowers from mid to late summer. Plant it in full sun to partial shade, in dry-medium to medium conditions, with loamy soil, sandy soil, poor soil or dry soil. Space plants 24–36 inches apart for healthy growth and airflow.

Pests & Diseases
Downy mildew, rust, Sclerotinia stalk or head rot, Verticillium wilt, and Phomopsis stem canker affect sunflowers. Choose resistant hybrids, rotate away from susceptible broadleaf crops, and avoid dense stands. Remove volunteer sunflowers and do not save seed from moldy heads or plants with stalk decay.
Sunflower moths, beetles, cutworms, aphids, birds, and squirrels may damage plants or seed heads. Scout buds and leaves, handpick insects, and protect ripening heads with breathable barriers.
