Minimum: 50+ Seeds
The Black-Eyed Susan With a Secret Scent
Brush past this plant on a warm afternoon and you'll catch something unexpected from a native prairie flower: a genuine anise fragrance rising from crushed foliage. Sweet Black-Eyed Susan pairs that surprise scent with the classic golden-yellow blooms and dark centers of its more common cousins, but on a taller, sturdier plant that shrugs off summer heat and drought without complaint. It's a genuine tallgrass prairie native, built for long, hot summers and years of reliable return.
Who Grows Sweet Black-Eyed Susan?
The native prairie gardener wanting an authentic tallgrass species with real garden presence.
The pollinator gardener wanting long-blooming golden flowers for bees and butterflies.
The heat and drought-prone climate gardener needing a perennial that thrives under summer stress.
The cut-flower gardener wanting sturdy, long-lasting golden stems with a pleasant fragrance.
What This Anise-Scented Native Actually Is
Rudbeckia subtomentosa, called sweet black-eyed Susan or sweet coneflower, is a clump-forming perennial native to prairies and moist meadows across the central and eastern US, notable among its genus for the anise scent released when foliage is crushed or bruised. Plants grow 3 to 5 feet tall, forming sturdy, branching clumps topped with golden-yellow, daisy-like flowers with dark brown centers, blooming over a long stretch from midsummer into fall. It tolerates heat, humidity, and drought better than many prairie natives once established, and its height and long bloom period make it a genuine workhorse in a native perennial border. Hardy in zones 4 through 9, it spreads slowly by rhizome to form an expanding clump over time.
