Helianthus angustifolius (Swamp Sunflower) Seed, PA Ecotype
Description
Helianthus angustifolius is a tall, clump-forming perennial that grows 3–6 feet high. It is native to wetlands and moist habitats in the southeastern United States. From late summer to fall, it produces vibrant yellow flowers with dark centers, attracting pollinators and adding bright color to landscapes.
Swamp sunflower is a popular choice for wetland restoration and naturalized plantings due to its tolerance for poorly drained soils and periodic flooding. It supports biodiversity by providing nectar for bees, butterflies, and other pollinators. Its upright growth habit and showy blooms make it a striking addition to ecological landscapes and rain gardens.
