Photo: Hydrangeas

These are the most beautiful blue hydrangeas I have seen. I believe they are growing in Lee's garden.

From the page Hydrangeas! Hydrangeas! 

One can rarely change the intensity of a color (how strong or pale the color is). The intensity develops for a number of reasons: the heredity of a particular hydrangea variety, weather conditions (hot or cold, humid or dry), health of the plant, and possibly other natural factors. Fertilizing hydrangeas once or twice a year may result in a little more saturated color simply because the health of the plant may be improved.
