Helianthus neglectus is a species of sunflower known by the common names neglected sunflower. It is native to the southwestern United States in southeastern New Mexico and western Texas.[1]
Helianthus neglectus grows on sand dunes and other sandy soil. This wildflower is an annual herb up to 200 cm (almost 7 feet) tall, growing from a thick, fleshy taproot. One plant produces 1-5 flower heads containing 21-31 yellow ray florets surrounding 150 or more red or purple disc florets.[2][3]
Helianthus neglectus hybridizes with several other species in the region: H. annuus, H. debilis, and H. petiolaris.[3]
