Helianthus angustifolius (Swamp Sunflower) Unity Grown

Helianthus angustifolius is a tall, upright, clump-forming perennial wildflower native to the eastern half of the United States. Growing to 5-8' tall, swamp sunflower produces profuse numbers of small, bright yellow blooms from late summer until fall, and these blooms are valuable to a wide variety of pollinators. In addition, through the fall, flower heads turn to rich seed, which is prized by a variety of songbirds and other wildlife.

Helianthus angustifolius performs best in a good variety of wet soil types, as the name swamp sunflower might imply. Plants do best in full sun, and can most often be found in nature in wetlands and near bodies of water. Aside from inland swamps, swamp sunflower's salt tolerance also makes it a great pick for planting in coastal gardens or near salt marshes as well. With flowers prized by bees, butterflies, and birds, swamp sunflower is an excellent pick for a variety of garden locations, provided you have the space for such a tall wall of flowers.
