Hemerocallis 'Mighty Chestnut' (Daylily) is a compact perennial boasting a profusion of large, chestnut brown flowers, 5.5 in. across (14 cm), adorned with a bold burgundy halo above an orange throat. The broad, rounded, ruffled petals open wide to reveal the perfect flower form. Blooming in mid to late summer, the attractive blossoms are held neatly above its compact mound of arching, linear leaves. Each flower typically lasts at least 16 hrs (extended blooms) but no more than 24 hours, 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. An excellent border plant that is spectacular when planted in drifts. This late midseason tetraploid is dormant (deciduous).

  • Grows up to 30 in. tall (75 cm) and 18-24 in. wide (45-60 cm).
  • 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.
  • Ideal choice for beds and borders, cottage gardens, and city gardens.
  • 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.
  • 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.
