About sunflowers (Helianthus annuus):
Sunflowers are annuals, native to the U.S., which grow to three to ten feet tall. Cultivated sunflowers often do not grow true from seed. They will revert back to the wild variety within several generations. Flowers are about three to five inches in diameter. The brown center of the flowers is comprised of disk florets. Twenty to forty ray florets surround the brown center and are golden yellow. Blooming is from mid to late summer. Sunflowers prefer full sun and slightly dry soil.
