Blue Hydrangea (Pink Hydrangea?)

Hydrangeas color can be affected by the pH of the soil. Blue comes from low pH (acid soil) and pink comes from more neutral or alkaline soil (pH above 6).

 

This plant was transplanted last year so it's still trying to figure out whether it's in acid or neutral soil.
