Hemerocallis Pandoras Box (Reblooming Daylily)

Highly fragrant and vigorous, Hemerocallis ‘Pandora’s Box’ is a lovely early midseason Daylily that produces an abundance of large, 4 in. wide (10 cm), cream flowers with a contrasting cranberry-purple eye and emerald green throat. Its broad ruffled petals do not fade in the sun.

Highly fragrant and vigorous, Hemerocallis 'Pandora's Box' is a lovely early midseason Daylily that produces an abundance of large, 4 in. wide (10 cm), cream flowers with a contrasting cranberry-purple eye and emerald green throat. Its broad ruffled petals do not fade in the sun. Each flower typically lasts no more than 24 hours (thus the common name 'Daylily'), opening up in the morning and withering during the forthcoming night, possibly replaced by another one on the same scape (flower stalk) the next day. Blooming from early to midsummer, and potentially later in the season, this diploid Daylily is evergreen.

  • Grows up to 24 in. tall (60 cm) and spreads slowly via rhizomes to 18-24 in. (45-60 cm).
  • An ideal choice for shrub borders or perennial beds, as ground covers on slopes or in containers near the patio.
  • Often called the 'perfect perennial' because of its numerous qualities: showy flowers, drought tolerance, heat stress immunity, ability to grow in most hardiness zones, and low care requirements, this Daylily is a remarkable and stunning addition to the garden.
  • Thrives in full sun to part sun in average, moist, but well-drained soils. While it performs well in a wide range of soils, fertile loam is preferred. Tolerates heat and summer humidity, but thorough watering is required to ensure its foliage remains attractive.
  • Daylilies attract butterflies and hummingbirds but are toxic to cats. Rabbits tend to avoid daylilies.
  • No serious pest or disease issues. Keep an eye out for mites, aphids, thrips, or daylily rust.
  • The best time to plant Daylilies is in early fall or early spring.
  • After flowering, remove spent blooms and seedpods to improve the appearance and encourage rebloom. When all the flowers on a scape are finished, cut off the scape close to ground level. Remove dead foliage from daylilies as they die back in the fall.
  • Bred by Talbott in 1980, it won multiple awards including the Honorable Mention in 1984 and the Award of Merit in 1987.
