Growing Non-GMO Rudbeckia Double Gloriosa Flower Seeds
For first-year blooms, direct-sow Rudbeckia Double Gloriosa seeds outdoors in the fall, or start seeds indoors 5 to 7 weeks before your last frost date after cold, moist stratification. Surface sow and press seeds gently into the soil rather than burying them, since light helps trigger germination. Space plants 12 to 18 inches apart in average, well-draining soil.
Water regularly while plants are getting established, then reduce watering once mature, since this variety tolerates heat and drought well. Deadhead spent blooms throughout the season to encourage continued flowering, and avoid high-nitrogen fertilizers, which can push leafy growth at the expense of blooms.
Rudbeckia Double Gloriosa in the Flower Garden
Tall, sturdy stems hold the large double blooms well above the foliage, making this variety a standout in borders, cottage gardens, and mixed flower beds. Its long bloom season from summer through fall provides a steady supply of golden-yellow color even as other plants begin to fade, while its nectar-rich flowers draw in bees, butterflies, and other pollinators.
Harvesting Rudbeckia Double Gloriosa
For fresh arrangements, cut stems just as the double blooms begin to open rather than waiting for them to unfurl, which extends vase life fully. This variety also makes an excellent dried flower; for drying, harvest once blooms are fully open and hang stems upside down in a warm, dry, well-ventilated space.
About Rudbeckia Double Gloriosa Garden Seeds
Gloriosa Daisy is a double-flowered selection of the native North American wildflower Rudbeckia hirta, honored with an All-America Selections award in 1961.
Though technically a biennial to short-lived perennial, it is most often grown as an annual since it reliably produces its showiest blooms in the first year when given an early start.
Its large, ruffled, mum-like double blooms set it apart from the simpler single-petaled forms more commonly seen in gardens and meadows.
Tips From Our Gardeners
Don't skip the stratification step if you want blooms the first summer. Seeds sown without a cold treatment often wait until their second year to put on their best show.
