Helianthus heterophyllus is a species of sunflower known by the common names variableleaf sunflower[2] and wetland sunflower. It is native to the coastal plain of the southern United States from Texas to North Carolina.[3]
Helianthus heterophyllus is a perennial sometimes as much as 120 cm (4 feet) tall, spreading by means of underground rhizomes. Leaves and stems are hairless or almost hairless; leaves appear white on the undersides because of an abundance of wax. One plant can produce 1-5 flower heads, each with 12–18 yellow ray florets surrounding as least 100 red or brown disc florets. The species grows in wet sandy soils at low elevations.[4]
