About Rudbeckia
Rudbeckia, famously known as Black-Eyed Susan, is an iconic American native perennial celebrated for its golden-yellow daisy-like petals framing dark, cone-shaped centers. Extremely tough and dependable, Rudbeckia delivers long-lasting color from midsummer straight through the late autumn frosts, making it an indispensable staple for borders, native gardens, and mass plantings.
Key Features
- Pollinator & Bird Friendly: Nectar attracts bees, butterflies, and beneficial insects during summer; seed heads feed goldfinches and songbirds through winter.
- Exceptional Heat & Drought Resistance: Thrives in hot, sunny conditions and handles dry soil once established.
- Deer & Rabbit Resistant: Coarse, hairy foliage deters grazing deer and rabbits.
- Excellent Cut Flower: Sturdy stems and long-lasting blooms make them ideal for fresh floral arrangements.
Grower’s Tip: Rudbeckia adapts well to most soil types as long as it has good drainage. Deadhead spent flowers during early summer to prolong blooming, but consider leaving late-season seed heads intact for winter bird feeding and autumn garden interest.
