Answer: B: SOIL
Hydrangea macrophylla, aka bigleaf hydrangea has the unique ability to change the color of its blooms. This is due to the pH level of the soil in which it is planted.
If the soil is more alkaline, the blooms will be pink or red. If the soil is more acidic, the blooms will be blue or purple. This means that by simply adjusting the pH level of the soil, you can change the color of your hydrangea flowers. Not only is this a fun and unique feature, it also allows for easy garden customization. Imagine having a blue and pink hydrangea garden, all in the same bed, just by adjusting the pH level of the soil!
