daylily 'Berlin Lemon'


Hemerocallis 'Berlin Lemon', commonly known as the daylily due to each flower typically lasting just one day, is a perennial plant celebrated for its striking flowers. The 'Berlin Lemon' variety boasts vibrant lemon-yellow blossoms that captivate with their bright hue. Each flower displays a classic trumpet shape, opening up from a narrow base to a flared and broad petal display. The petals may exhibit a slightly ruffled edge, adding to their ornamental appeal. In terms of foliage, the daylily presents long, slender, arching leaves that are a rich green color, forming an attractive, grassy clump from which flower stalks rise. These stalks, known as scapes, bear multiple buds, ensuring a succession of blooms over a period of time. When in bloom, the 'Berlin Lemon' daylily injects a burst of sunny color into the garden, with the flowers creating a strong visual contrast against its own verdant foliage and the surrounding greenery.

    Daylilies, like the Hemerocallis 'Berlin Lemon', typically need to be watered deeply once a week, providing about an inch of water each time. During hot or dry periods, this may increase to twice a week. It's important to water at the base of the plant, avoiding the foliage to minimize the risk of disease. In terms of the amount, aiming for approximately 0.62 gallons per square foot per week should suffice in normal conditions. Make sure the soil is well-drained as daylilies do not like to sit in waterlogged soil.

  • sunLight

    Daylilies such as the Hemerocallis 'Berlin Lemon' thrive in full sun. They require at least six hours of direct sunlight daily to perform best. The ideal spot would be an area that gets unfiltered sunlight throughout the day, or only light shade for a portion of the day. They can tolerate partial shade, but blooming might be reduced in these conditions.

They can survive during the winter in temperatures as low as -20°F and can handle summer heat up to 90°F or more. The ideal growing temperatures for daylilies are between 60°F and 75°F.

  • scissorsPruning

    Pruning Hemerocallis 'Berlin Lemon', commonly known as daylilies, involves removing spent flower stems to encourage new blooms and maintain a tidy appearance. After flowering, cut back the foliage if it becomes brown or unsightly. In late fall or early spring, remove dead material from the previous growing season. Pruning is generally done on an as-needed basis throughout the blooming season and for overall plant health annually.

  • circleLife cycle

    The Daylily 'Berlin Lemon' begins its life cycle when a seed germinates, usually with the onset of warm temperatures in spring. The seedling emerges and develops into a juvenile plant, forming a set of roots and foliage. As a perennial, it enters a phase of vegetative growth, where leaves and root systems mature and the plant establishes itself. In subsequent seasons, the plant enters the reproductive phase, producing sturdy stems with buds that bloom into bright yellow flowers during the summer. After flowering, the plant sets seed, which can disperse to create new plants if conditions permit. During the fall, the foliage of 'Berlin Lemon' dies back with the onset of cooler temperatures, and the plant enters dormancy for the winter, conserving energy in its roots for the next growing cycle.

    • Propogation time

      Spring-Early Summer

    • Propogation: The most popular method of propogating the daylily 'Berlin Lemon' is by division of its clumps. This perennial plant tends to form dense clusters of fleshy roots known as rhizomes, which can be divided to create new plants. Division is best performed in early spring or late fall when the plant is not in active bloom. Gardeners should carefully dig up the clumps, ensuring they lift a generous amount of roots to avoid damage. Using a sharp spade or knife, the clump can then be divided into smaller sections, each with at least one fan of leaves and a portion of the root system. These sections are then replanted at the same depth they were growing previously, spaced about 18 to 24 inches (45 to 60 cm) apart to allow ample room for growth. Suitable watering is necessary after replanting to help establish the new divisions.
