This clump-forming perennial produces narrow, grass-like leaves and tall, sturdy stems that bring vertical interest to borders, meadows, and rain gardens. Its autumn flowers are a welcome source of color when many other perennials have finished blooming, and they attract pollinators such as bees and butterflies.\u003c\/p\u003e\u003cp\u003eIdeal for naturalized plantings, pollinator gardens, and moist landscape areas, Swamp Sunflower tolerates wet soils better than many sunflowers. It combines well with ornamental grasses and other native perennials, adding a cheerful, wildflower look to the late-summer and fall garden.\u003c\/p\u003e\u003ch2\u003ePlant Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBright yellow, daisy-like flowers with dark centers\u003c\/li\u003e\n\u003cli\u003eNarrow, lance-shaped green leaves on upright stems\u003c\/li\u003e\n\u003cli\u003eBlooms in late summer to fall\u003c\/li\u003e\n\u003cli\u003eAttracts bees, butterflies, and other pollinators\u003c\/li\u003e\n\u003cli\u003eTolerates moist to wet soil conditions\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 Helianthus angustifolius\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Moist to wet, well-drained soil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Requirements:\u003c\/strong\u003e Moderate to high; keep soil consistently moist\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Habit:\u003c\/strong\u003e Upright, clump-forming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSDA Hardiness Zones:\u003c\/strong\u003e 5-9\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 3-6 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacing:\u003c\/strong\u003e 18-24 inches apart\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePlanting \u0026amp; Care\u003c\/h2\u003e\u003cp\u003eSow Swamp Sunflower seeds indoors 6-8 weeks before the last frost or directly outdoors after the danger of frost has passed. Press seeds lightly into the soil surface and keep them moist; light aids germination. Maintain consistent moisture until seedlings are established. Thin or transplant seedlings to the recommended spacing to allow good air circulation.\u003c\/p\u003e\u003cp\u003eOnce established, Swamp Sunflower is relatively low-maintenance. Water regularly, especially during dry spells, and provide support in windy areas if stems become tall. Deadhead spent flowers to encourage continued bloom, or leave seed heads for birds. Divide clumps every few years to maintain vigor.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003e100 Swamp Sunflower seeds (Helianthus angustifolius).\u003c\/p\u003e","brand":"Blake's Flora \u0026 Soil","offers":[{"title":"Default Title","offer_id":67824742367542,"sku":"FOLIA2-1141","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4884\/8694\/files\/il_fullxfull.6545127625_p5yq.jpg?v=1793004418","url":"https:\/\/blakesflora.com\/products\/100-swamp-sunflower-seeds-helianthus-angustifolius-native-wildflower","provider":"Blake's Flora \u0026 Soil","version":"1.0","type":"link"}
