Try This Activity: Color Changing Flowers

March 5, 2021

We have a fun activity and science experiment you can try with your family. Along with the story behind it here at Nicholasville Nursing & Rehab.

As we reminisced on Valentine’s past and other times we’ve received flowers, our residents shared with each other their favorite flowers. Resident, Lynn Noe, shared that the Carnation was her favorite flower. 💐

Lynn then asked the group – Do you know how they get all their bright colors?

We did not and Lynn, along with another resident who owned a florist, shared that this is done with food coloring.

We then asked – How long would it take to turn a color?

As an experiment, we decided to separate some of the white carnations into vases and added food coloring. We watched excitedly through the week’s end. After a few days, we discovered it worked! They noted that in the future they would leave the flowers in the color a bit longer.

Here are the instructions to try this flower experiment:

Color Changing Flowers


  1. Trim down the stems of the flower so they fit your cups or glasses.
  2. Add water to each cup.
  3. Then put about 10-15 drops of food coloring in the water and stir around a bit.
  4. Add at least one carnation to each glass of colored water.
  5. Check-in on the flowers every couple of hours and observe any changes.

Tip: The longer the flowers stay in the color, the more vibrant the color will become.
