alum root 'Red Lightning'


The 'Red Lightning' variety of Coral Bells is noted for its striking foliage. The leaves are large with an electrifying bright red and yellow pattern. The main color of these leaves is a deep mahogany red, marked with veins that stand out in an electric lime-yellow to gold color, creating a dramatic contrast. This pattern gives an impression of a lightning bolt, which is likely how the name 'Red Lightning' was conceived. The texture of the leaves is also a point of interest; they are somewhat ruffled and have a bumpy, veined surface that adds depth to the visual appeal of the plant. In addition to the foliage, 'Red Lightning' Coral Bells produce delicate flowers. The flower stems rise above the mound of leaves, giving way to small, bell-shaped flowers. These blooms are typically white to pale pink and add a soft, airy touch to the plant, contrasting with the boldness of the leaves. The blossoming period adds an extra layer of interest, making this Coral Bells variety a colorful and dynamic addition to any garden display.

  • water dropWater

    Coral Bells prefer evenly moist soil, so water them deeply to saturate the root zone when the top inch of soil feels dry to the touch, which might be once or twice a week depending on weather conditions. During periods of drought or extreme heat, this may mean watering as often as every other day. It is essential to avoid letting them dry out completely, but be careful not to overwater as Coral Bells do not like soggy soil. A good rule of thumb is to provide Coral Bells with about one gallon of water per plant, per week, under normal conditions.

  • sunLight

    Coral Bells thrive best in partial shade, but they can tolerate full sun in cooler climates if they are kept adequately moist. The ideal spot for them is where they receive morning sunlight and are protected from the hot afternoon rays. They can also grow in full shade, but their colors might be less vibrant and their growth less robust.

  • thermometerTemperature

    Coral Bells are hardy in a wide range of temperatures and can survive in temperatures as low as 20°F and as high as 80°F. Their ideal growing conditions are between 60°F and 70°F, which encourages healthy growth and vibrant foliage. They can tolerate slight variations outside this range but should be protected from extreme cold or heat.

  • scissorsPruning

    Prune Coral Bells to remove dead or damaged foliage and to maintain their neat shape. This is typically done in early spring or late fall. Deadheading spent flowers can encourage additional blooming. Generally, Coral Bells require minimal pruning; simply cut back any tattered leaves in the spring before new growth starts to keep the plant looking its best.

  • bambooSoil

    The best soil mix for Coral Bells (Heuchera 'Red Lightning') is well-draining, rich in organic material, with a pH ranging from slightly acidic to neutral (pH 6.0-7.0). A mixture of one-part garden soil, one-part peat moss or compost, and one-part perlite or coarse sand is ideal to facilitate good drainage while retaining adequate moisture.

  • plantRepotting

    Coral Bells (Heuchera 'Red Lightning') typically don’t require frequent repotting and can be repotted every 2-3 years. It is best to repot in the spring, just before the growing season, if the plant has outgrown its current container or the soil has degraded.

  • circleLife cycle

    The Heuchera 'Red Lightning', commonly known as Coral Bells, begins its life cycle when seeds are sown or when it's propagated from a division of the root. Germination occurs in a temperature-controlled environment, and seedlings are usually grown until they are large enough to handle. Once planted out in partial shade or full sun, the Coral Bells undergo a vegetative growth phase, developing distinctive foliage with jagged edges and a unique pattern of red and yellow veining. During the blooming season, usually from late spring to early summer, Coral Bells produce tall flower stalks bearing clusters of small, bell-shaped flowers, attracting pollinators and beneficial insects. After flowering, seeds may be set, completing the reproductive cycle, though many cultivars, including 'Red Lightning', are often propagated vegetatively for consistency. In the following seasons, the plant enters a period of dormancy during the colder months, only to regrow from the crown once the conditions become favorable again in spring.

      Spring-Early Summer

    • Heuchera 'Red Lightning' is commonly propagated through division, which is best done in spring or fall, when the plant is not in active growth. To propagate by division, carefully dig up the entire plant, gently teasing it apart into smaller sections, ensuring that each section has a piece of the root system attached. These sections can then be replanted into moist, well-draining soil, keeping them at the same depth they were originally growing. It's advisable to water the newly planted divisions thoroughly to help establish their roots in the new location. This method is the most popular because it is straightforward and typically results in a high success rate, with new plants often flowering in the following growing season.
