Fun Facts

  • 🌱 Heuchera is commonly called 'Coral Bells' because of its bell-shaped flowers, and Coral Belle is one of the most vibrant coral-colored cultivars available.
  • 🌱 The foliage of Heuchera plants contains compounds that can develop deeper coral-red coloring when exposed to cooler temperatures, enhancing the plant's ornamental value in fall.
  • 🌱 Coral Belle is native to North American woodlands and was hybridized to enhance the brightness of flower color, making it more visually striking than wild species.
