Helianthus giganteus, the giant sunflower or tall sunflower, is a species of Helianthus native to the eastern United States and eastern and central Canada, from Newfoundland west to Alberta south to Minnesota, Mississippi, and South Carolina.[2][3][4]
Description
[edit]Helianthus giganteus is a perennial herbaceous plant that can grow up to 4–5 metres (13–16 ft) tall. The leaves are slender and lanceolate. The flower heads are bright yellow, up to 7 cm (3 in) in diameter. They are most commonly found in valleys with wet meadows or swamps[5][4] and even near river banks.
Cultivation and use
[edit]The Choctaw Indians of the southeastern United States have traditionally cultivated the Helianthus giganteus and made a palatable bread by mixing the ground sunflower seed with that of ground maize.[6]
