double yellow daylily


Hemerocallis fulva 'Flore Pleno', commonly known as the double daylily, is a perennial plant that displays unique and striking blooms. The flowers are distinctive with multiple layers of petals, giving them a full, fluffy appearance that sets them apart from the single-layered petals of a typical daylily. Each flower is a vibrant orange color, with a slightly darker orange or reddish hue toward the petal's center, which may radiate outward to the petal edges—a feature that adds depth to the flower's look. The petals of the double daylily have ruffled edges that contribute to their lush, ornamental quality. The blossoms emerge from strong, green stalks that are part of a clump of arching, blade-like leaves. The foliage is a rich, deep green color and adds to the plant's overall lushness. The leaves may also serve as an elegant backdrop to the floral display, enhancing the overall visual impact of the plant. This particular daylily variant blooms in the summer, producing many buds that open over a span of several weeks. Each individual flower lasts only for a single day, true to the name "daylily," but due to the number of buds produced, the blooming period is extended. As the plant matures, it forms a dense cluster that can be quite expansive, which makes it an attractive and robust selection for gardens or as borders. The double daylily can thrive in a variety of conditions and is known for its hardiness and ease of care, making it a popular choice among gardeners who wish to add a touch of drama and color to their landscapes.

  • skullToxicity

    • To humans

      Daylilies are not generally considered toxic to humans, and in fact, some cultures eat the flowers, buds, and tubers as food. However, individuals with certain sensitivities may experience mild stomach upset if they ingest parts of the plant not typically consumed. As with any plant, it's important to be cautious and knowledgeable about the specific parts that are edible to avoid any potential gastrointestinal discomfort.

    • To pets

      Daylilies are known to be toxic to cats and can cause severe kidney damage if ingested by them. Symptoms of daylily poisoning in cats include vomiting, lethargy, and lack of appetite, which can progress to kidney failure if not treated promptly. Immediate veterinary care is crucial if a cat ingests any part of a daylily plant. Dogs are not as sensitive to daylilies, but ingestion can still cause mild gastrointestinal upset. It's always best to prevent pets from ingesting any part of the daylilies to avoid these risks.

As needed
  • water dropWater

    Daylilies should be watered deeply about once a week, allowing the soil to dry between watering sessions. Regular watering during their active growing season, which is spring through fall, is essential for establishing plants and ensuring vigorous blooming. An approximate guideline is 1 inch of water per week, either from rainfall or supplemental watering. For a standard garden, watering with 0.623 gallons per square foot every week will satisfy their needs. However, during periods of extreme heat or drought, increase watering frequency to prevent stress.

  • sunLight

    Daylilies thrive in full sun conditions where they can receive at least 6 to 8 hours of direct sunlight daily. The ideal spot is an area with bright morning light and some protection from the intense afternoon sun, particularly in hotter climates. If grown in too much shade, the blooming might be reduced and stems can become leggy as they reach for the light.

  • thermometerTemperature

    Daylilies prefer temperatures between 60°F and 90°F for optimal growth. They are hardy and can survive minimum temperatures as low as -20°F once established. While they can handle heat well, prolonged exposure to temperatures exceeding 90°F may cause stress and affect blooming. They are adaptable to various conditions but perform best when the temperature range is maintained within their comfort zone.

  • scissorsPruning

    Pruning daylilies involves removing spent flower stalks after blooming to maintain a tidy appearance and prevent seed production, which can reduce the next year's blooms. Prune out any damaged or yellow leaves throughout the growing season to encourage healthy growth. The best time for a major clean-up, including removing old foliage, is early spring or immediately after flowering has finished.

  • circleLife cycle

    Hemerocallis fulva 'Flore Pleno', commonly known as the double orange daylily, begins its life cycle as a seed, which after germination, develops into a small seedling with basic root and shoot structures. As the plant matures, it develops long, strap-like leaves and a strong root system, typically forming a clump. Each season, it produces tall scapes that bear the distinctive double orange blooms, which are each open for just one day before withering. After flowering, if pollination occurs, seed pods may form and eventually release seeds, continuing the reproductive cycle. During winter or unfavorable conditions, the plant enters a period of dormancy, with the foliage dying back, and then resumes growth once conditions become favorable again. The daylily has a perennial lifecycle, which allows it to bloom every year for several years, and it can also be propagated by dividing the clumps of its rhizomatous root system.

      Late summer to early fall

    • The most popular way to propagate the daylily, particularly Hemerocallis fulva 'Flore Pleno', is by division. This is typically done in late summer to early fall, after the plant has finished blooming. Gardeners should gently lift the clump of the daylily from the ground using a spade or fork, taking care not to damage the roots excessively. Once out of the ground, the clumps can be separated by hand or cut with a sharp knife into smaller sections, each with a few fans of leaves and a portion of the root system. These divisions should then be replanted promptly at the same depth they were growing before and watered well. This method is effective because it helps maintain the vigor of the plant and ensures that the new plants will be true to the parent’s characteristics.
