Fun Facts

  • 🌱 Witch Hazel 'Diane' is a hybrid between Hamamelis mollis (Chinese witch hazel) and Hamamelis japonica (Japanese witch hazel), combining the superior fragrance of the Chinese species with the vigor and cold-hardiness of the Japanese species.
  • 🌱 The spidery flower petals can contract and expand in response to temperature changes, allowing the plant to protect delicate flowers from frost and cold snaps—a remarkable cold-hardiness adaptation.
  • 🌱 The plant's common name 'witch hazel' likely derives from the use of forked branches as divining rods by dowsers, though the etymology remains debated; it has nothing to do with witches or actual hazels.
