Sunflower

Saw-tooth Sunflower (Helianthus grosseserratus) is a distinctive North American native plant. Tall reddish-purple stems and sharply toothed leaves support clusters of yellow blooms that feed insects and seed-eating birds. It matures at approximately 96 inches tall and flowers from mid to late summer through early to mid fall. Plant it in full sun to partial shade, in dry-medium through medium-wet conditions, with loamy soil or clay soil. Space plants 36–48 inches apart for healthy growth and airflow.

Tall Sunflower (Helianthus giganteus) is a distinctive North American native plant. Clusters of yellow flowers crown tall purplish stems, creating late-season color and abundant food for pollinators and birds. It matures at approximately 96 inches tall and flowers from early to mid summer through mid to late summer through early to mid fall. Plant it in full sun to partial shade, in medium to medium-wet conditions, with loamy soil, clay soil or sandy soil. Space plants 36–48 inches apart for healthy growth and airflow.

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.”
