Swamp Sunflower, also known as Narrowleaf Sunflower, is a great fall bloomer to add to your landscapes if you have moist or wet areas. Helianthus angustifolius makes an excellent option for a rain garden or along ponds and streams, but thrives just as well in medium soils. It’ll produce many blooms and attracts a variety of bee species that you don’t get to see too often. This perennial sunflower is listed as an Extirpated Species in Pennsylvania, which I’m hoping we can help bring back! It’s also a host plant to the Silvery Checkerspot butterfly and American Goldfinches will forage on its seedheads throughout winter.
