Beach Sunflower occurs on beaches, in sand hills, around the edges of fields, on roadsides, and along railroad tracks. It is an annual with a tap root. Stems are erect to sprawling, 2-5 feet in height, green in color, pubescent, and freely branched from the lower and middle nodes. Leaves are alternate, petiolate, ovate to deltoid in outline, glabrous to pubescent, and with irregularly toothed margins. Flowers are produced in heads. The heads are solitary and axillary from the upper nodes on long peduncles, 9-15 inches in length. Each head has 20-30 lanceolate phyllaries, 11-20 yellow ray flowers, and 30-80 reddish disc flowers.
