About Western, Sunflower Seed, Sunflower Seed
Don't let the name fool you! This is mainly an Eastern native plant. Known botanically as Helianthus occidentalis, the Western Sunflower has a distinctive growth habit that makes it easy to recognize. Most of its leaves cluster in a rosette at the plant’s base, while a slender stalk rises from the center and can reach about three feet tall. A brilliant yellow flower head appears at the top of the stem. Because the stalk bears very few leaves, the species is also commonly called the “naked-stemmed sunflower” or “few-leaved sunflower.”

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.
