Beside this, can you change the color of a flower?
Cut a small piece of the stem off of the flower. Put the flower in the container of food coloring and water. The only way the petals can change color is if the food coloring travels up the stem and goes to the petals. After about one day, the petals of the flower will turn from white to the color of the food coloring.
How long does it take to change the color of a flower with food coloring?
The petals should become colored after a few hours. It may take as long as 24 hours, however, depending on the flower. You can set the colored flowers in plain water or flower preservative, but they will continue to drink water, changing the pattern of the color over time.
Why are the flowers colorful?
Brightly colored flowers attract different insects to come visit the flower. When insects like bumblebees perch on a flower's petals looking for nectar, pollen gets stuck to their bodies. When insects fly off to another flower, the pollen is transferred to the new flower.
