help Hydrangea macrophylla (Bigleaf Hydrangea) FAQ
Why do Bigleaf Hydrangea flowers change color from pink to blue?
The flower color of *Hydrangea macrophylla* shifts based on the soil pH and the availability of aluminum ions. In acidic soil (pH below 6), aluminum becomes available to the plant, turning the flowers blue, while alkaline soil (pH above 7) turns them pink.
Where is the Bigleaf Hydrangea originally from?
Hydrangea macrophylla is native to the maritime climates of Japan. It has been cultivated there for centuries before being introduced to European botanists in the 18th century.
What is the proper way to prune a Bigleaf Hydrangea?
Most traditional Bigleaf Hydrangeas bloom on old wood, meaning they set their flower buds for the next year shortly after blooming in late summer. Pruning should be done immediately after the flowers fade; pruning in spring will remove the buds and prevent blooming.
Is color-shifting a common trait in garden shrubs?
No, this pH-dependent color shifting is a trait that is highly unique among common garden shrubs. It makes *Hydrangea macrophylla* particularly popular for gardeners who like to experiment with soil amendments like sulfur or lime.
