Did you know

  • Unlike true climbing hydrangea, Schizophragma has single heart-shaped sepals rather than four-petaled bracts around each flower cluster.
  • The cultivar 'Moonlight' has silvery-blue leaves with dark veins, providing ornamental value even when not in bloom.
  • It attaches to surfaces with adhesive aerial rootlets and can eventually cover an entire stone wall.
  • In Japanese forests it spirals up tall camphor and cryptomeria trees, blooming high in the canopy.
  • Its dried flower heads persist through winter, adding architectural interest to the garden in the cold months.
