Rudbeckia triloba 'Prairie Glow'

three-lobed coneflower or brown-eyed Susan

Rudbeckia triloba 'Prairie Glow' has our attention! With brightly colored flowers of yellow with a bright red eye fading to a glowing orange to bronze, this native beauty brings fire to the sunny border. Its multi-branching habit provides dense flower cover, more so than the straight species, and its late blooming time, starting in July and flowering right through to October, makes this a valuable pollinator plant.

three-lobed coneflower Interesting Notes

Found from Vermont to Texas to Utah to Georgia, Rudbeckia triloba prefers sandy or loamy, moist soils but can tolerate periods of drought. Commonly residing in moist fields, it likes disturbed habitats such as along roadsides or rail lines. The wide variety of habitats this plant tolerates display its adaptable appeal, as long as there is full sun. In a happy location, Rudbeckia will self-sow which allows easy propagation for this short-lived plant.

Rudbeckia triloba is in full bloom after Rudbeckia ‘Goldsturm’ begins to fade but before Rudbeckia fulgida var. fulgida comes into its full glory. It has earned its place in our mid-height meadow where plants must tolerate an early summer mow and biennial burns while being less than 3’ tall to maintain sight lines. Three-lobed coneflower supports a multitude of native bees including digger bees and carpenter bees as well as the specialist pollinator, Andrena rudbeckiae. The plant is self-pollinated but that doesn’t stop the wasps, butterflies, and flies from visiting. The foliage is also fed upon by a variety of native beetles, which while it doesn’t help the lower foliage, it does help support a full range of insects for their necessary habitat.

Rudbeckia triloba 'Prairie Glow' Growing and Maintenance Tips

Prefers sandy or loamy, moist soils, but is drought resistant. Spreads slowly by rhizomes. Deadhead to prolong blooming season. Propagate by seed, cuttings and division. Cut back to the ground after first frost and mulch to protect roots for the winter. Outstanding in mass plantings, as a border perennial, low maintenance gardens, and rock gardens.
