The edges of the leaves may be fringed or slightly wavy, adding to the ornate character of the plant. In addition to its striking leaves, Heuchera 'Lime Marmalade' produces delicate stems that rise above the foliage clump, and during the blooming season, small, bell-shaped flowers appear. These blossoms are typically of a lighter, more subdued hue, often white or pale pink, and form loose clusters along the vertical stems. The subtle flowers offer a soft visual contrast with the exuberant leaf color and can attract a range of pollinators to the garden.

  • water dropWater

    Coral Bells, or Heuchera 'Lime Marmalade', should be watered regularly to maintain moist but not waterlogged soil, particularly during the growing season. It's best to water them deeply once a week, allowing for about 1 gallon of water to reach the roots, depending on the size of the plant and the weather conditions. During hot, dry periods, more frequent watering may be necessary whereas, in cool, damp weather, less is required. It's important to avoid overhead watering to prevent disease, so water at the base of the plant. During the winter, reduce the amount of water to prevent root rot as the plant's growth slows down.

  • sunLight

    Coral Bells thrive in part shade to full sun, but the 'Lime Marmalade' variety performs best with morning sun and afternoon shade to protect its vibrant foliage. Ensure it's planted in a location where it receives at least 3 to 6 hours of sunlight daily. Direct, harsh afternoon sun should be avoided, as it can scorch the leaves, especially in hotter climates.

  • thermometerTemperature

    Coral Bells are quite hardy and 'Lime Marmalade' can tolerate temperature extremes, surviving in USDA hardiness zones 4-9. They can generally handle temperatures as low as -30°F and as high as 80°F, but they thrive in temperatures between 60°F and 70°F. Providing mulch can help to regulate root temperature and protect the plant in both heat and cold.

  • scissorsPruning

    Pruning Coral Bells helps to maintain their shape and encourage a healthy growth habit. Remove any dead or damaged leaves as needed throughout the year to keep the plant looking its best. In early spring, before the onset of new growth, cut back the entire plant to remove any old foliage and promote fresh, vibrant leaves. Pruning is generally done annually or whenever necessary to remove spent leaves.

  • circleLife cycle

    Heuchera 'Lime Marmalade', commonly known as Coral Bells, begins its life cycle with seed germination, occurring when conditions are moist and warm. The seedlings establish a rosette of leaves at the soil surface and develop a root system. After the rosettes mature, Coral Bells enter a vegetative state, characterized by the growth of the lime-green, ruffled foliage that is a hallmark of this cultivar. The plant eventually enters a reproductive phase, usually in late spring or early summer, producing tall, slender stalks with small bell-shaped flowers that attract pollinators. Once pollination takes place, seeds are produced, and after dispersal, the plant may go through a period of dormancy, especially in colder climates, retreating to the rosette stage and conserving energy for the next growing season. Over several seasons, the clumps of foliage expand as the plant grows, until it eventually needs division to rejuvenate and maintain vigor.

    • Propogation time

      Spring-Early Summer

    • Heuchera 'Lime Marmalade', also known as Coral Bells, is commonly propagated by division. The best time to propagate Coral Bells by division is in the spring or fall when the plant is not in active bloom. To propagate, carefully dig up the entire plant, making sure to keep a substantial amount of roots intact. Gently separate the crowns by pulling or cutting through the root ball to create smaller plants, each with a portion of the root system. Replant these divisions immediately at the same depth they were originally growing, spacing them about 12 to 18 inches apart (30 to 46 centimeters) to allow for growth. Water the new plants thoroughly to help establish their roots. This method encourages healthy, vigorous new growth and can help to rejuvenate older, overcrowded clumps of Coral Bells.
