Hydrangea macrophylla petals. Photo taken in Gramado, Rio Grande do Sul, Brazil. This photo shows the colors details of an <i>Hydrangea macrophylla</i> that grows in a soil with medium to high levels of acidity (low pH), which results in pale blue colors of the flowers (petals) rather than a vivid blue (that is a color commonly present in this kind of flowers along with pink and white colors).
