Narrowleaf Sunflower

Helianthus angustifolius

Narrowleaf Sunflower is a tall, sun-loving perennial native to the Southeastern and Mid-Atlantic U.S., thriving in moist meadows, streambanks, and open woodlands. It reaches 3–6 feet tall and is crowned in late summer and fall with an explosion of daisy-like yellow flowers, often continuing until frost. True to its name, its narrow, lance-shaped leaves give the plant an elegant, airy appearance, even when not in bloom. This species is especially valuable for pollinators during a time when other nectar sources are scarce, attracting a range of native bees, skippers, and migrating monarchs. Once the blooms fade, seed heads provide food for songbirds like finches and sparrows. It spreads by rhizomes and forms bold colonies, making it ideal for naturalized plantings and rain gardens.
