🌸 What Is Hydrangea ‘Phantom’?
Hydrangea ‘Phantom’ is a cultivar of Hydrangea paniculata. It produces very large, dense flower panicles that open creamy white in summer and often take on soft pink tones as autumn approaches.

🌿 What Soil Does Hydrangea ‘Phantom’ Like?
This hydrangea prefers soil that is:
