Q.Hydrangea Colors
Does the color of hybridized hydrangeas change if you change the pH of the soil? I heard a few years ago that newer varieties or hybridized hydrangeas keep their original color. Is this true?

Hydrangeas with white flowers cannot change their color. But I do think all blue and red/pink hydrangea varieties can change their color if the soil pH is changed sufficiently. Some varieties may require an even larger pH change than others to chage their color, though.
