  • These reblooming daylily varieties bear flowers with ruffled petals in varying shades of yellow. Green Flutter and Mini Stella flowers feature green throats.

  • Stella D’Oro blooms from May through August, while the Mini Stella blooms from June through September. The Happy Returns cultivar blooms from June through October, while the Green Flutter displays flowers in June and July.


  • Reblooming daylily cultivars range in height from about 1 to 2 1/2 feet. Spreads typically range from 1 to 1 1/2 feet.


  • Most reblooming daylilies thrive in USDA hardiness zones 3 to 9. The Stella D’Oro cultivar grows well in USDA zones 3 to 10.
