It is one of the most dramatic native wildflowers in the South, and in Louisiana, it is perfectly timed to fuel the last monarchs of the season as they pass through on their way to Mexico.\u003c\/p\u003e\u003ch3\u003eBotanical Profile\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFamily:\u003c\/strong\u003e Asteraceae (Daisy family)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNative Range:\u003c\/strong\u003e Eastern United States from New York to Florida and west to Texas; native to Louisiana's wet prairies, bayou edges, and moist open areas\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSDA Hardiness Zones:\u003c\/strong\u003e 5–10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature Size:\u003c\/strong\u003e 5–8 feet tall; spreads by rhizome to form colonies\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBloom Time:\u003c\/strong\u003e September–November (one of the latest-blooming native wildflowers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSun:\u003c\/strong\u003e Full sun\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e Moist to wet; tolerates clay and periodic flooding; thrives along bayou edges and in rain gardens\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eEcological Role\u003c\/h3\u003e\u003cp\u003eSwamp Sunflower's late-season bloom makes it one of the most ecologically critical native wildflowers in the South — providing abundant nectar for migrating monarchs, painted ladies, and cloudless sulphurs in October and November when almost nothing else is blooming.
