Saturday, May 30, 2009 – Hydrangea
Hydrangea macrophylla –
In most species the flowers are white, but in some species (notably H. macrophylla), can be blue, red, pink, light purple, or dark purple. In these species the exact color often mirrors the pH of the soil; acidic soils produce blue flowers, neutral soils produce very pale cream petals, and alkaline soils results in pink or purple. This is the caused by a color change of the flower pigments in the presence of aluminum ions which can be taken up into hyper-accumulating plants.
The soil in Beverly Hills must be alkaline.
