PLACEMENT & CULTIVATION
Gloriosa daisies arose from black-eyed Susans circa 1957, with double the number of chromosomes. Known as tetraploids, they possess great vigor and offer an array of colors—sizzling bright oranges and gold, subtle pastel color schemes, and even deep red and chocolate hues. A must for wildflower gardens combined with grasses and coneflowers and valuable in the cutting garden and border for their energetic mid-summer through fall bloom. Deadhead for even more flowers and mulch to conserve soil moisture during high summer. It may overwinter in zones 5-8 but is most often grown as an annual. Self-sows.
