Fun Facts

  • 🌱 Japanese holly (Ilex crenata) is often called 'boxwood's evergreen cousin' because of its similar fine foliage texture, but it is a true holly with tiny, serrated leaves instead of the smooth leaves of boxwood.
  • 🌱 The name 'Ilex' comes from the Latin word for holm oak, and the genus includes over 600 species of holly plants worldwide, ranging from tiny shrubs to large trees.
  • 🌱 Steeds Hollow is a non-fruiting male cultivar, making it clean and low-maintenance—no berry litter or seedlings to manage, unlike some other holly varieties.
