Helianthus angustifolius, commonly known as swamp sunflower, is a species of sunflower native to the southeastern United States. It is a perennial plant that typically grows in wetlands, along the edges of ponds, marshes, and in other moist or swampy areas. Here are some key characteristics of the swamp sunflower:

Appearance: Swamp sunflowers are known for their bright and showy yellow flowers. The flowers have a typical sunflower appearance with a central disk surrounded by ray-like petals. The leaves are long and narrow, hence the species name "angustifolius," which means narrow-leaved.

Size: These plants can reach heights of 3 to 7 feet (approximately 1 to 2 meters).

Habitat: As the name suggests, swamp sunflowers thrive in wet or swampy areas, often found in the wild in low-lying, waterlogged regions.

Blooming Season: Swamp sunflowers typically bloom in late summer or early autumn, providing a burst of yellow color to wetland areas.

Wildlife Attraction: The flowers of swamp sunflowers are a source of nectar for pollinators like bees and butterflies. Additionally, the seeds are a food source for birds.

Cultivation: Helianthus angustifolius is sometimes cultivated as an ornamental plant in gardens, especially in areas with moist or waterlogged soil. They can provide an attractive and late-season source of color.
