Bigleaf Hydrangea
Did you know?

The flower color of Bigleaf Hydrangeas (Hydrangea macrophylla) can be manually changed, except for white cultivars. Aluminum absorption is the key, as acidic soils allow their roots to absorb aluminum from the soil, while alkaline soils prevent aluminum absorption. By adjusting the pH of the soil near the roots, you can change the color of the flowers.
