Did you know

  • Bigleaf hydrangea flower color is pH-dependent — acidic soil (below 6) produces blue flowers, alkaline (above 7) produces pink.
  • The color change is caused by aluminum availability in the soil — aluminum is absorbed only in acidic conditions.
  • 'Hydrangea' comes from Greek meaning 'water vessel' — both for the flower's shape and its thirst.
  • Hydrangea macrophylla is the official flower of Japan's rainy season (tsuyu) and Father's Day.
