alum root 'Shanghai'


Heuchera 'Shanghai', commonly known as Coral Bells, is a decorative perennial plant with a striking appearance. It features a compact mound of dense foliage that adds texture and color to garden spaces. The leaves of the 'Shanghai' variety are particularly notable for their dark purple to nearly black tint, with a hint of a silver overlay that gives them a somewhat metallic sheen. The foliage is often rounded, with lobed edges and a ruffled look that adds a touch of elegance. In contrast to the dark leaves, the Coral Bells 'Shanghai' produces tall, slender stems that rise above the foliage and carry small bell-shaped flowers. These flowers are usually a delicate pale pink or white, creating an appealing contrast against the dark leaves. They typically bloom in late spring to early summer, providing an airy, whimsical quality to the plant's overall appearance. The combination of the dark, lustrous leaves and the dainty flowers can make the Heuchera 'Shanghai' a focal point in any garden setting. It can be used as a border plant, in rock gardens, or in mixed container plantings, bringing both color and texture to the landscape throughout the growing season.

As needed
  • water dropWater

    The Coral Bells should be watered thoroughly at the soil level to avoid wetting the foliage, which can lead to fungal diseases. It's best to check the top inch of soil for dryness and provide water when it feels dry to the touch, typically once a week, but this may vary depending on climate conditions and soil type. During hotter seasons, they may require more frequent watering, perhaps twice a week. Generally, providing half a gallon to a gallon per plant during each watering session should suffice, ensuring that the water penetrates deeply to encourage strong root growth without over-saturating the soil.

  • sunLight

    Coral Bells thrive best in partial shade conditions, particularly in a spot that offers morning sun and afternoon shade to protect the delicate foliage from scorching. They can tolerate full shade as well, but the foliage colors may not be as vibrant. Avoiding direct, harsh afternoon sunlight is ideal to maintain the health and color of the plant.

  • thermometerTemperature

    Coral Bells are hardy and can survive in a temperature range between about -25°F to 80°F. The ideal growing conditions for this plant are between 60°F and 70°F, which encourages strong growth without stress from extreme temperatures. Winter hardiness is typically down to -25°F, so this plant can survive in a variety of climates if properly mulched during the colder months.

  • scissorsPruning

    Coral Bells benefit from pruning to remove any damaged or old leaves and to promote a more compact, tidy growth habit. The best time for pruning is in the early spring or late winter before new growth begins. Cut back any spent foliage from the previous season, and deadhead spent flowers to encourage additional blooms. This may be done several times throughout the growing season as necessary to keep the plant looking its best.

  • circleLife cycle

    The life cycle of Heuchera 'Shanghai', commonly known as Coral Bells 'Shanghai', begins with seed germination, occurring in a warm, moist environment where the tiny seeds sprout and develop into seedlings. As the seedlings grow, they produce a basal rosette of ruffled, deep purple leaves that are evergreen in mild climates. The plant reaches maturity and enters its flowering stage in late spring to early summer, sending up slender, erect stalks topped with dainty bell-shaped flowers that attract pollinators. After pollination, these flowers may produce viable seeds that can be dispersed to start new plants. Coral Bells 'Shanghai' is a perennial, so after flowering, the plant continues to grow and can be divided in the spring or fall to propagate new plants and maintain vigor. In colder climates, the plant may die back in the winter, but the root system remains alive, ready to regrow in the spring.

      Spring-Early Summer

    • Propogation: Heuchera 'Shanghai', commonly known as Coral Bells, is propagated most effectively through division, which should be done in the spring or fall. Division involves carefully lifting the mature plant and gently separating the crowns with your hands or a sharp knife, ensuring that each division has several leaves and its own root system. Once divided, the new plants can be replanted at the same depth they were previously grown, in a mixture of well-draining soil. It's essential to keep the newly planted divisions well-watered until they are established. This method allows gardeners to quickly increase their stock of Heuchera 'Shanghai' while also rejuvenating older plants that might have become woody or less vigorous at the center.
