Hydrangeas change color, depending on the acidity of the soil they are planted in. My mother, readers will be shocked to know, was a master gardener. She tried, but not much of her knowledge stuck with me. I do remember her planting nails around her hydrangea to try to get it to change color. She had one that was six feet tall and pink on one side, blue on the other.

Lee's hydrangea must be in acid soil because of the deep and beautiful blue - at that's without nails!
