This heirloom wildflower brings a bold, natural look to meadows, pollinator gardens, rain gardens, and the back of perennial borders. Its narrow, grass-like foliage and upright habit make it a strong vertical accent, while the daisy-like flowers provide a valuable late source of nectar for bees and butterflies.\u003c\/p\u003e\u003cp\u003eNative to the eastern United States, Swamp Sunflower is prized for blooming in late summer and fall when many other perennials have finished. It tolerates moist to wet soils and is an excellent choice for low-lying areas, pond edges, and naturalized plantings. With 100 seeds, you can establish a generous patch or share plants with fellow gardeners.\u003c\/p\u003e\u003ch2\u003ePlant Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTall native perennial with bright golden-yellow flowers\u003c\/li\u003e\n\u003cli\u003eLate-season bloomer that supports pollinators\u003c\/li\u003e\n\u003cli\u003eHeirloom, non-GMO seed for naturalized and wildlife gardens\u003c\/li\u003e\n\u003cli\u003eTolerates moist to wet soil and seasonal flooding\u003c\/li\u003e\n\u003cli\u003eExcellent for meadow, rain garden, and border plantings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGrowing Information\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBotanical Name:\u003c\/strong\u003e \u003cem\u003eHelianthus angustifolius\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Type:\u003c\/strong\u003e Herbaceous perennial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunlight:\u003c\/strong\u003e Full sun to partial shade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Moist to wet, well-drained to boggy soils\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Requirements:\u003c\/strong\u003e Medium to high; tolerates wet conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Habit:\u003c\/strong\u003e Upright, clump-forming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBloom Season:\u003c\/strong\u003e Late summer to fall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature Height:\u003c\/strong\u003e Tall; typically 3 to 6 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacing:\u003c\/strong\u003e 18 to 24 inches apart\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePlanting \u0026amp; Care\u003c\/h2\u003e\u003cp\u003eSow Swamp Sunflower seeds indoors 6 to 8 weeks before the last frost, or direct sow outdoors after the danger of frost has passed. Press seeds lightly into the soil surface and keep them moist, as light aids germination. Seedlings can be transplanted once they have several sets of true leaves. Space plants 18 to 24 inches apart in a sunny location with moist soil.\u003c\/p\u003e\u003cp\u003eOnce established, Swamp Sunflower is relatively low-maintenance. Water regularly during the first growing season to help roots settle in. In subsequent years, it can tolerate drier conditions but performs best with consistent moisture. Cut back stems in late winter or early spring before new growth emerges. Divide clumps every few years if they become overcrowded.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003e100 Swamp Sunflower seeds (\u003cem\u003eHelianthus angustifolius\u003c\/em\u003e), non-GMO heirloom garden seed.\u003c\/p\u003e","brand":"Blake's Flora \u0026 Soil","offers":[{"title":"Default Title","offer_id":67739764228406,"sku":"EDNA-341","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4884\/8694\/files\/il_fullxfull.8014074276_485j.jpg?v=1792115391","url":"https:\/\/blakesflora.com\/products\/100-swamp-sunflower-seeds-tall-native-heirloom-flower-for-garden-planting","provider":"Blake's Flora \u0026 Soil","version":"1.0","type":"link"}
