Why have your blue agapanthus turned white?
Agapanthus colour is normally genetically determined, as such a white flower cannot turn blue. This does happen with flowers such as Hydrangea, where a blue or white flower can be turned pink - this is a result of the pH or acidity level of the soil
Do pennies placed in the soil next to hydrangea plants effect the color?
Not that I've heard. Many hydrangea strains will have different flower colors, depending on the aluminum content of the soil. When there is available aluminum, the flowers will be blue. When there is no available aluminum, they'll be pink. This doesn't work for white hydrangeas. You can add aluminum sulfate, which is available at most garden centers, to turn pink flowers blue. In order to turn blue flowers pink, raise the soil pH by adding a liming material, and the aluminum will form insoluble compounds and no longer be available to the plants.
