There's a little science (and a lot of soil) behind why some hydrangea flowers change color from blue to pink. We break down the basics.

For great-looking flower beds, pay attention to creating masses of color and using the heights of plants correctly.

Augment the lighter tints with the pure color. For instance, if yellow is the dominant color, most of the yellow flowers will be lighter tints of yellow with limited additions of bright, pure yellow.
