Did you know you can change the color of your hydrangeas? They're affected by the pH of your soil, so (and I'm going from memory, so I could be wrong).. the more acidic = blue, alk = pink.. and I would guess the more neutral = white. :)
I believe you are suppose to put nickel or other metals in the soil to turn blue & acid like lemon juice for the pink, but I might be mixed up. Since I only have potted plants it makes it hard to grow hydrangeas, but I love how full they are.
