Hemerocallis sp. in a landscape setting

Hemerocallis spp. 
Daylily



  • Water use: Low to moderate; requires more regular watering when flower buds are present. Water stress may cause flower buds to abort.
  • Light: Full sun to partial shade for pastel colors.
  • Size: 12" to 3-4' tall, depending on cultivar; spread can equal height.
  • Plant habit: Clumping, fan-shaped, herbaceous perennial; evergreen or deciduous, depending on cultivar.
  • Season of bloom: Summer; most cultivars bloom for a few weeks each summer, some repeat blooming after a brief rest.

  • Culture: Grows best in rich, well-drained soils; doesn't require much fertilization.Winter appearance of Hemerocallis
  • Maintenance: Old flowers of some cultivars may not drop cleanly; may be necessary to remove dead flowers for maximum appearance. Old flower stalks may be removed after blooming or left until spring. Old leaves and flower stalks may be removed in spring. To maintain peak appearance, divide the clumps when they become crowded and stop blooming well; in our gardens, the daylilies seem to need dividing about every 8-10 years.
  • Pests/Diseases: Relatively insect- and disease-free. Some years, thrips can cause some petal distortion and color streaking.
  • Other: Each flower lasts about a day. Some cultivars are faintly fragrant. Gardeners in cold areas should select deciduous (not evergreen) cultivars to ensure hardiness. Flower buds are edible.
