daylily 'Corky'


The plant known as Hemerocallis 'Corky' is commonly referred to as the Daylily 'Corky'. This plant is celebrated for its distinctive flower blooms, which have a unique coloration and form. Its flowers display a rich blend of yellow to pale orange petals, resembling the warm hues observed during a sunset. The blossoms may also have a subtle, raspberry-red eye zone that centers around a vibrant greenish-yellow throat, creating a striking contrast that draws attention. These flowers typically display six elongated petals that are somewhat ruffled along the edges, giving them a graceful, yet slightly untamed appearance. Daylily 'Corky' blooms are known to open up during daylight and last for just one day before being replaced by new blooms in a continuous cycle throughout the blooming season. The foliage of this plant consists of long, arching, strap-like leaves that are a deep green color, forming an attractive, lush clump that serves as a backdrop to its remarkable flowers. The plant possesses a robust and hardy nature, making it a popular choice for gardeners who desire a touch of vibrant color without requiring excessive maintenance.

    Daylilies, like the Hemerocallis 'Corky', prefer consistently moist soil, especially during the active growing season in spring and summer. Watering should be done deeply and thoroughly, allowing the top inch of soil to dry out slightly between watering sessions. Typically, aim to water daylilies about once a week with approximately 1 to 1.5 inches of water each time, but be prepared to adjust depending on weather conditions, such as increased frequency during hot, dry periods or less during rainy spells. Over the course of a month, this would amount to about 4 to 6 gallons of water per plant, depending on the size of the daylily and local rainfall.

  • sunLight

    Daylilies, including 'Corky', flourish in full sun to partial shade conditions. They perform best when they receive at least six hours of direct sunlight daily. A spot that offers morning sun with some afternoon shade is ideal to protect them from the intense heat of late afternoon sun. However, 'Corky' is adaptable and can also do well in filtered light conditions, provided it gets enough light to bloom effectively.

  • thermometerTemperature

    The 'Corky' variety of daylilies is hardy and can tolerate a wide range of temperatures, surviving winter lows down to around -20°F and summer highs well above 90°F. However, they grow best in moderate climates where temperatures range between 70°F and 85°F during the growing season. Daylilies are adaptable and will remain dormant during the colder months and revive as temperatures rise in the spring.

  • scissorsPruning

    Pruning daylilies, such as 'Corky', primarily involves deadheading spent blooms and removing dead foliage to encourage more flowers and prevent disease. Pruning can be done throughout the blooming season, as needed. The best time for more significant pruning, such as cutting back dead growth, is in the early spring or after the plant has finished blooming for the season. This not only tidies the plant but also helps conserve its energy for the next growing cycle.

  • circleLife cycle

    The life of the Daylily 'Corky' typically begins with seed germination, which occurs when the conditions of warmth and moisture are favorable, leading to the emergence of a small shoot and root system. After germination, the plant enters a vegetative growth stage, where it develops a clump of strap-like foliage and an extensive root system that helps it survive periods of drought. As it matures, 'Corky' reaches a stage of flowering, generally in late spring to early summer, where it produces unique, trumpet-shaped flowers that are often a blend of yellow and copper tones, each bloom lasting just one day. After pollination, which may be facilitated by insects, 'Corky' can produce seeds in a capsule, although many gardeners propagate it through division of the clumps every few years to maintain vigor. Once the flowering season is over, the plant enters a period of dormancy during colder months, especially in regions with harsh winters, where the foliage dies back and the plant conserves energy within its root system. In the following growing season, the cycle begins anew with fresh growth from the crown, continuing its perennial life cycle.

      Late Summer to Early Fall

    • Hemerocallis 'Corky', commonly known as the daylily, is generally best propagated through division, which is the most popular method for this perennial plant. Division should ideally be performed in the early spring or after the blooming period in late summer to early fall. To propagate through division, a gardener should dig up an established clump of daylilies and gently pull the fans, or individual plant segments with leaves and roots, apart. Each fan should have a good set of roots and at least two or three leaves. These individual fans can be planted directly into a well-prepared garden bed or pot, ensuring the crown is set at about one inch below the surface of the soil. Once planted, watering should be done thoroughly to help establish the newly divided plants.
