narrow-leaf sunflower
Helianthus angustifolius L.
Helianthus angustifolius L., a member of the Asteraceae family, is native to the south-central and eastern United States, including regions such as Alabama, Florida, and Missouri. It is commonly known as narrow-leaf sunflower and is typically found in wet, low-lying habitats such as bogs and swamps, though it can also tolerate drier, well-drained soils. The species was first described in 1753.
Description
Helianthus angustifolius L. is a sunflower species that occurs in coastal and inland areas of the eastern U.S., from Texas to New York and as far west as Missouri. It is associated with moist environments, including wetlands and swampy areas, and is occasionally found in drier, gravelly soils. The plant is not highly drought-tolerant. Taxonomically, there has been some confusion regarding the type specimen, with earlier references incorrectly citing material that was not original to the species. Clarifications by botanists such as Heiser and Reveal have helped resolve these issues.
