The Pink Velvet Hydrangea is one of the most beautiful colors of the Hydrangea family. Hydrangeas are fascinating because the color of their flowers can change dramatically. It is much easier to control or alter the pH of the soil in a container than it is in the ground.
On the other hand, hydrangeas often change color on their own when they are planted or transplanted. They are adjusting to the new environment. It is not unusual to see several different colors on one shrub the next year after planting.
It is much easier to change a hydrangea from pink to blue than it is from blue to pink. Changing a hydrangea from pink to blue entails adding aluminum to the soil. Changing from blue to pink means subtracting aluminum from the soil or taking it out of reach of the hydrangea.
