How to Grow Daylily
Daylily
Hemerocallis spp.
flowerDaylilies are herbaceous perennials known for their trumpet-shaped flowers that typically bloom for just one day, hence their name. These hardy, low-maintenance plants produce numerous buds, ensuring continuous blooms throughout their flowering season. They are versatile garden additions that come in hundreds of cultivars with varying colors, sizes, and bloom times.

Growth Stages
Dormancy
3-4 months (November-March in most regions)Most varieties go dormant in winter, with foliage dying back and disappearing entirely. Evergreen and semi-evergreen types retain some foliage.
Cut back dormant foliage in late fall or early spring. No watering needed. Mulch in cold climates for extra protection.
Spring Growth
4-6 weeksNew shoots emerge from the crown. Foliage begins to elongate, forming clumps of strappy leaves.
Remove winter mulch gradually as temperatures warm. Begin regular watering. Apply balanced fertilizer (10-10-10) as growth begins.
Bud Formation & Blooming
6-12 weeks depending on variety and conditionsFlower scapes (stems) emerge from the center of foliage clumps, producing buds. Flowers open in morning and close by evening. Multiple blooms occur sequentially over weeks.
Provide consistent moisture during bloom period. Deadhead spent flowers daily for continued blooming. Apply phosphorus-rich fertilizer (5-10-10) to encourage more buds.
Post-Bloom Senescence
4-8 weeksFlowers cease blooming as day length decreases and plant energy shifts to storing reserves in rhizomes. Foliage remains green but growth slows.
Continue watering but reduce frequency. Remove spent flower scapes at their base. Reduce or stop fertilizing.
Summer Rest/Second Wind
2-4 weeks for reblooming varietiesSome reblooming cultivars may produce new scapes in late summer/early fall after a brief rest. Non-reblooming varieties remain dormant.
Minimal care required. Water only during extreme heat or drought. Reblooming types benefit from light deadheading and occasional watering to trigger repeat flowers.

Common Pests
-
Remove infected foliage and discard. Avoid overhead watering. Improve air circulation. Apply fungicide if severe (sulfur or neem oil). Choose rust-resistant varieties.
-
Spray affected flowers with insecticidal soap or neem oil. Remove and discard heavily infested buds. Encourage beneficial insects like ladybugs.
-
Spray with strong water stream to dislodge. Use insecticidal soap or neem oil if infestation is heavy. Introduce natural predators like ladybugs.
-
Increase humidity by misting. Spray with insecticidal soap or miticide. Avoid over-fertilizing with nitrogen, which increases susceptibility.
-
and
Hand-pick in early morning or evening. Use copper tape barriers around plant bases. Apply diatomaceous earth. Beer traps or iron phosphate baits are effective.
Uses
Edible Flowers & Buds
CulinaryCertain Hemerocallis varieties produce edible flowers with a slightly sweet flavor, popular in Asian cuisines. Flower buds can be stir-fried or dried, while open petals work in salads, garnishes, and desserts. [source]
Cut Flowers & Floral Design
HouseholdThough individual flowers last only one day, daylilies can be cut for fresh arrangements, with multiple buds opening sequentially over several days. Reblooming varieties extend arrangements significantly. [source]
Traditional Asian Medicine
MedicinalHemerocallis flowers and buds have been used in traditional Chinese and Asian medicine for centuries, purported to have anti-inflammatory and cooling properties. Dried buds (called 'golden needles') are used in herbal preparations. [source]
Pollinator Support
WildlifeDaylilies attract hummingbirds, butterflies, bees, and other pollinators, making them valuable for wildlife gardens and supporting local ecosystems. [source]
Landscape & Garden Design
HouseholdWith hundreds of cultivars offering varied colors (reds, yellows, pinks, purples, bi-colors), sizes (miniature to giant), and bloom times, daylilies serve as foundational perennials for borders, mass plantings, containers, and xeriscaping. [source]

Harvest Tips
Daylilies are ornamental plants not typically harvested like vegetables. However, edible flower varieties can have petals picked for culinary use. Pick petals early in the morning when flowers first open. Some gardeners harvest buds for stir-frying before flowers open. Deadhead spent flowers by pinching or cutting at the base of the scape to encourage more blooms.
Fun Facts
- 🌱 The name 'daylily' comes from the Greek words 'hemera' (day) and 'kallis' (beauty)—each flower blooms for exactly one day, opening in the morning and closing by evening, yet plants produce dozens of buds ensuring weeks of continuous bloom.
- 🌱 Daylilies are one of the most collectable perennials, with over 80,000 registered cultivars! Serious hobbyists and breeders worldwide compete to develop new colors, patterns, and bloom characteristics, with prize specimens selling for hundreds of dollars.
- 🌱 Most daylily varieties are sterile or produce few seeds, so propagation happens primarily through rhizome division, meaning all plants of a cultivar are genetic clones—a fact that has made them popular for breeding and hybridization programs.
