Hydrangea L.
Hydrangeas are hardy shrubs or sometimes small trees that are native to many areas of the world. Their large, copious, beautiful flowerheads make them popular for foundation plantings, and many cultivated varieties exist. Hydrangea macrophylla flowers have a pigment whose color depends on soil acidity, may be white, blue, purple, or pink. Online References:
