Changing of colours, not just trees...Hydrangea!

Hydrangeas fascinate me with their ability to change colours so dramatically.  After they are planted or transplanted, they can change colour on their own!  You will have better luck with a hydrangea changing colour in a container as opposed to being planted in the ground. This is due to the pH level of the soil which can be controlled within the container.  Want to change the colour?...you'll need more alkaline (pH) in your soil.  If the pH level in your soil is below 6, flowers turn blue.  If the pH is above 7, flowers turn pink or even red.  If your pH level is in-between (6-7) blooms may be purple or a mix of pink & blue on a single shrub.
