Interested in growing hydrangeas? The acidity level of the soil used to grow them determines the colour of the flowers:
[F]or most French hydrangeas (Hydrangea macrophylla), the flower color indicates the pH of the soil. In strongly acid soil (pH below 6), flowers turn blue. In alkaline soil (pH above 7), flowers turn pink or even red. In slightly acid or neutral soil (pH 6 to 7), blooms may be purple or a mix of blue and pink on a single shrub. Keep in mind that selections vary in their sensitivity to pH. For example, 'Ami Pasquier' stays crimson in all but the most acid soil and 'Purple Tiers' remains purple.
from an article in Southern Living, May 2012
You cannot do anything about white hydrangeas, but if you have no idea what kind of a soil is in your garden you can simply grow the hydrangeas in flowerpots, where you can control the acidity level.
I will finish this post with a photo of mop head hydrangeas in France from one of my favourite and newly discovered blogs, The Room Outside, by garden designer Lisa Cox. She gives plenty of advice and her photography is beautiful.
