Rudbeckia, Sweet Black Eyed Susan

Rudbeckia, Sweet Black-Eyed Susan (Rudbeckia subtomentosa)

Sweet Black-Eyed Susan is a tall, late-blooming native perennial that fills prairies and pollinator gardens with masses of golden-yellow flowers and a sweet, subtle vanilla scent. Native to the central and southeastern U.S., this species stands out for its long bloom season, large clumps, and wildlife value. It attracts pollinators from midsummer into fall and supports beneficial insects throughout the growing season. With its height, fragrance, and resilience, Rudbeckia subtomentosa is a star performer in native meadows, rain gardens, and layered prairie plantings.

Key Characteristics

• Late-Season Blooms for Pollinators and Monarchs
  Flowering from July through October, this Rudbeckia provides vital nectar during the late-summer and fall migration of monarch butterflies, along with bumble bees, honey bees, and native wasps. Its open flower shape offers easy access to a wide range of pollinators.

• Fragrant Foliage and Flowers
  Unlike many other coneflowers, Rudbeckia subtomentosa emits a light, sweet scent-sometimes compared to vanilla or anise-from both its foliage and flowers, making it a sensory addition to wildlife gardens and cut flower arrangements.

• Tall and Upright With a Graceful Presence
  Growing up to 5-6 feet tall, Sweet Black-Eyed Susan adds height and structure to planting designs. It combines beautifully with grasses and late-blooming prairie plants like asters, goldenrods, and ironweed for succession planting and vertical layering.

• Supports Beneficial Insects and Seed-Eating Birds
  After flowering, the seedheads persist into winter, providing food for finches and other small songbirds. The dense clumps also offer overwintering shelter for beneficial insects, including solitary bees and predatory wasps.

• Adaptable to Moist or Average Soils
  Sweet Black-Eyed Susan prefers medium to medium-wet soils but tolerates periodic drought once established. It's ideal for rain gardens, stormwater areas, meadows, and sunny borders, especially in naturalistic or restoration plantings.
