Award-winning Rudbeckia triloba is a biennial or short-lived perennial which produces masses of rich golden yellow flowers, 1-2 in. across (2-5 cm) from mid-summer to frost, no matter what the weather is like. Each flower has 6-12 ray-like petals surrounding a dark chocolate central cone, providing fantastic and long-lasting color in the summer garden. Its basal rosette of three-lobed leaves persists through the winter, creating an attractive winter ground cover. Extremely easy to grow, this plant may naturalize easily and remain in the garden thanks to its ability to freely self-seed.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
  • Densely branched, this Coneflower usually grows up to 2-3 ft. tall (60-90 cm) and 12-18 in. wide (30-45 cm). Often tends to form colonies in the wild.
  • Thrives in full sun, in average, moist, well-drained soils. Tolerates light shade, but this plant may need support if grown in too much shade. Heat and drought tolerant.
  • Spectacular when massed in drifts, this is an excellent choice for perennial borders, cottage gardens, or naturalizing areas such as prairies or wildflower meadows. The flowers make excellent and long-lasting fresh-cut flowers.
  • Robust, low maintenance, and highly disease resistant, it is also deer resistant.
  • Remove spent flowers to promote further blooms, maintain a neat appearance, and prevent undesired self-seeding.
  • Native to the central-eastern United States.
