Helianthus angustifolius is a species of sunflower known by the common name narrowleaf sunflower or swamp sunflower. It is native to the south-central and eastern United States, found in all the coastal states from Texas to Long Island, and inland as far as Missouri.[2][3] It is typically found in the coastal plain habitat (both the Atlantic and Gulf), particularly in wet areas.
Helianthus angustifolius is often cultivated for its bright, showy yellow flowers. Leaves are long and narrow, up to 15 cm (6 inches) long. It is a perennial herb sometimes as much as 150 cm (5 feet) tall. One plant can produce 3-16 flower heads, each with 10-20 ray florets surrounding at least 75 disc florets.[4]

Speiceas de lus na gréine is ea Helianthus angustifolius. Tá sé dúchasach sna Stáit Aontaithe, sa taobh ó dheas agus ó thuaidh, sna stáit go léir ar an chósta ó Texas go Long Island, agus intíre chomh fada le Missouri. [1][2] De ghnáth, faightear é i ngnáthóg an mhachaire (an Atlantach agus an Mhurascaill araon), go háirithe i limistéir fhliucha.
