Unique flowering plants can change colors
Today’s Video of the Day from the American Chemical Society explains how some unique species of flowering plants known as Hydrangeas can change the color of their blossoms depending on the pH of the soil.
In other words, the colors of these plants can be transformed by simply changing the soil conditions. Blue flowers emerge from acidic soil, red flowers are grown in more basic soil conditions, and purple flowers can be created somewhere in between.
