Why did the flower color change after we got them home?
We bought a big pot of some beautiful hydrangeas at the supermarket about a week ago. The flowers were purple and white, just gorgeous. I put them under some grow lights and watered them every day, adding a little Miracle Grow to the water, for food.
Then, over about a week, the color of the flowers has started changing to blues and pinks. What is this?
Isnt there any way to keep them the original purples and whites?
