}}Helianthus atrorubens is a North American species of sunflower known by the common name Purpledisc sunflower. It is native to the southeastern United States. It is found in all the coastal states from Louisiana to Virginia, plus the inland states of Kentucky and Tennessee.[2]Helianthus atrorubens is a perennial herb sometimes as much as 200 cm (80 inches) tall. Most of the leaves are close to the base of the stem. One plant can produce 1-15 flower heads, each with 10-15 yellow ray florets surrounding 75 or more red or purple disc florets. The plant grows in mixed woods and along roadsides.[3] References1. ^The Plant List, Helianthus atrorubens L. 2. ^Biota of North America Program 2014 county distribution map 3. ^Flora of North America, Helianthus atrorubens Linnaeus, 1753.
