Key Features
- Growth Habit: Vigorous, herbaceous perennial that forms dense clumps of arching, strap-like foliage. Hemerocallis fulva can spread by underground rhizomes and may form large colonies over time, especially in favorable soil. Give plants room to spread or divide them periodically where a contained planting is desired.
- Bloom Color: Showy rich orange to orange-red flowers, often with deeper reddish-orange markings or throats. The triple-flowered form produces additional petals or petal-like floral segments, creating a much fuller appearance than standard Fulva daylilies.
- Bloom Season: Typically flowers during early to midsummer, with numerous buds opening successively over several weeks.
- Fragrance: Flowers generally have little to no noticeable fragrance.
- Fruit Flavor: Daylilies do not produce a conventional fleshy fruit. When fertile flowers are successfully pollinated, they may develop dry seed capsules containing dark seeds. Double or triple forms may have reduced fertility and are not grown for fruit production.
- Culinary Uses: Hemerocallis fulva has a long history as a food plant, particularly in Asian cuisine. Properly identified daylily young shoots, flower buds, and flowers have traditionally been prepared as food. However, individual sensitivity can occur, and ornamental plants treated with non-food-safe pesticides should not be eaten. Daylilies must never be confused with true lilies (Lilium spp.).
- Medicinal Uses: Hemerocallis fulva has a history of use in traditional herbal practices in Asia. However, historical use does not establish modern medical effectiveness, and ornamental daylilies are not recommended as a substitute for professional medical treatment.
- Possible Toxicity to Pets or Humans: Daylilies are highly toxic to cats. Ingestion of leaves, flowers, stems, or other plant material can potentially cause severe, life-threatening kidney injury in cats. Veterinary attention should be sought promptly if a cat has chewed or swallowed any part of a daylily. Daylilies are not known to cause the same severe kidney toxicity in dogs, although eating substantial amounts may cause digestive upset. Some people can also experience gastrointestinal discomfort after consuming daylilies.
- Wildlife & Pest Resistance: Flowers may attract hummingbirds, butterflies, bees, and other pollinating insects. Daylilies are generally tough and relatively resistant to serious disease, but deer and rabbits commonly browse the foliage and flowers. Potential problems include aphids, thrips, spider mites, slugs, snails, daylily rust, and crown rot.
- Planting Zone: Generally hardy in USDA Zones 3–9 and capable of surviving considerable winter cold once established.
- Sun Preferences: Full sun to partial shade. At least 6 hours of direct sunlight daily generally encourages the heaviest flowering. Plants tolerate partial shade but may produce fewer flowers.
- Soil Preferences: Adaptable to a wide variety of soils but performs best in fertile, moderately moist, well-drained soil. Established Fulva daylilies are notably tolerant of less-than-perfect garden conditions.
- Drought Tolerance: Moderate to high once established. Mature plants tolerate periodic drought quite well, although consistent moisture during spring growth and flowering encourages larger foliage and heavier blooming.
- Mature Size: Foliage generally reaches approximately 18–30 inches tall, while flower scapes may rise approximately 3–4 feet tall. Established clumps can spread several feet across if allowed to naturalize.
When and How to Prune
- Remove faded individual flowers as desired during the blooming season to maintain a neat appearance.
- Once a flower stalk has finished blooming and contains no unopened buds, cut the entire flower scape back near the base.
- Leave healthy green foliage intact after flowering. The leaves continue photosynthesizing and storing energy in the roots for the following growing season.
- Remove yellow, brown, damaged, or diseased leaves throughout the growing season as necessary.
- After the first hard frost causes the foliage to yellow or brown, cut dead foliage back to approximately 2–3 inches above the soil.
- Alternatively, dead foliage can be left through winter and removed before new growth emerges in early spring.
- Divide overcrowded clumps approximately every 3–5 years, or whenever plants spread beyond their desired area.
- Spring and late summer to early fall are generally good times to divide established daylilies.
Planting Instructions (3.5-Inch Pot into the Ground)
- Plant in spring or early fall, allowing enough time for roots to establish before periods of extreme heat or severe freezing weather.
- Choose a site receiving full sun to partial shade. Approximately 6 or more hours of direct sunlight generally provides the best flowering.
- Prepare the planting area by loosening the soil approximately 8–12 inches deep.
- Incorporate compost or other organic matter into poor soil if necessary to improve fertility, moisture retention, and soil structure.
- Dig a hole approximately twice as wide as the 3.5-inch nursery pot and about the same depth as the root ball.
- Carefully remove the daylily from its container and gently loosen tightly circling roots.
- Position the plant so the crown sits approximately at soil level or no more than about 1 inch below the finished soil surface. Planting too deeply can reduce flowering.
- Backfill around the root ball and gently firm the soil to remove large air pockets.
- Water thoroughly immediately after planting.
- Space individual plants approximately 18–24 inches apart. Wider spacing can be used where plants will be allowed to naturalize into large colonies.
- Apply approximately 1–2 inches of organic mulch around the plants to conserve moisture and suppress weeds, keeping excessive mulch away from the crown.
- Keep the soil consistently moist during the first growing season while roots become established.
- Once established, plants can tolerate considerably drier conditions, although supplemental watering during extended drought will improve flowering.
- Because Hemerocallis fulva can spread vigorously, periodically remove unwanted shoots or divide expanding clumps if you want the plants to remain within a defined garden area.
Overwintering Steps
- Triple Orange Fulva Daylilies are extremely cold hardy and generally require minimal winter protection in USDA Zones 3–9.
- Allow foliage to remain green until frost causes it to naturally yellow and die back.
- Once dormant, remove dead foliage in late fall or leave it until late winter or early spring.
- Cutting old foliage to approximately 2–3 inches above ground level helps create a clean planting area before new shoots emerge.
- Newly planted daylilies can benefit from approximately 2–3 inches of loose mulch during their first winter, especially in colder regions.
- Apply winter mulch after the ground becomes cold to reduce repeated freezing and thawing.
- Avoid piling thick, wet mulch directly over the crown, as excessive moisture can encourage rot.
- Established clumps usually require little additional winter protection.
- Remove excessive winter mulch in early spring as new green shoots emerge.
- Divide overly dense colonies when necessary to maintain vigorous growth and control their spread.
With their bold orange triple-style flowers, exceptional hardiness, vigorous growth, and old-fashioned garden character, Triple Orange Fulva Daylilies are an excellent choice for gardeners seeking dependable summer color. Their ability to naturalize makes them particularly useful for slopes, cottage gardens, large perennial borders, and mass plantings where they can develop into an impressive display that returns year after year.
