narrowleaf sunflower
Helianthus angustifoliusAlso known as Swamp Sunflower, Narrow-leaved Sunflower, Swamp Daisy
Narrowleaf sunflowers explode into bright golden blooms during late summer and autumn, filling damp meadows and roadside ditches with dense masses of yellow. Long, exceptionally slender leaves clothe tall reddish stems, distinguishing this plant from broad-leaved relatives. Native pollinators, especially long-tongued bees and butterflies, flock to the central dark disks for late-season nectar.
